The Lithuanian National Philharmonic Society

In the beginning of November 2019, the renewed Lithuanian National Philharmonic Society was presented to the public. One of the most significant renovations in the great concert hall was a unique LIGHTING SYSTEM specifically adapted to this space.

 Definite tasks were formulated for the installation of the lighting system, and they were taken on by UAB Scenos techninis servisas (STS), the company that implements integration projects.

“For over two decades now, we have been installing social and cultural spaces of various sizes, so we are happy to take on non-standard tasks. This project is unique because the entire lighting system is designed specially for this hall. We were looking for an implementation solution because no such system exists on the market. We have managed to achieve this only by uniting different manufacturers. This system is undoubtedly exclusive in Lithuania,” the Head of STS, Laurynas Paškevičius, says.

It is due to years of experience and proven partnerships that we can create such unique products.

This lighting system includes spotlights by Italian manufacturer Spotlight, the trusses and construction were made from the Dutch manufacturer Prolyte’s trusses and chain hoists, the cable collection system is by the Latvian manufacturer Winwood, and the lighting control system is provided by the British manufacturer ChamSys.

Emerging opportunities

The entire lighting system is state-of-the-art and opens up unlimited possibilities not only for performances by ensembles residing at the Philharmonic Society, but also for other art events that require non-typical lighting.

“There was absolutely nothing before, so in order to have at least some specific lighting you needed to install additional lighting equipment. Now it is possible to take full advantage of the current system, to create unique lighting designs and to do it all live. The possibilities of the new lighting system were noticed and highly appreciated by the audience that attended the opening events,” Norvydas Birulis, STS lighting engineer, says.

Subtle blending with the interior

One of the most important requirements has been implemented – the entirety of the new system blends with the interior and satisfies the requirements of heritage protection, i.e. it responsibly integrates into the architecture of the hall.

• The constructions (5 units) that reproduce the architecture of arches and match the color of the interior have been designed and installed throughout the perimeter of the hall.
• The constructions are equipped with remotely controlled lighting devices Spotlight:
• Spotlight Hyperion LED Fresnel TW with Lyra Spotlight ARC stage 3 – 18 units
• Spotlight Hyperion LED Fresnel 6C with Spotlight ARC stage 3 – 13 units
• Spotlight BEE50 BA/W – 66 units.

The lighting devices are painted the color that matches the ceiling color palette. Also, there is an integrated cabling system invisible to a human eye.

• These constructions are lifted by 250-kg lifting capacity Prolyft chain hoists mounted in the attics.

Noiseless operation

Another requirement was for the system to be working in an extremely quiet mode, i.e. the spotlights had to have convection cooling. “We seldom get requests for precise and quiet operation of mechanisms. We were looking for a manufacturer that could implement it in their products,” N. Birulis reveals.

Novel and unique lighting product

The Philharmonic Society renovation project did not set a requirement for integrating specific equipment or a manufacturer. Instead, it asked for the final lighting result on stage with very high parameters of light efficiency and system flexibility. Therefore, in Lithuania a new product was designed and manufactured by STS specialists, that was assembled from different foreign manufacturers.

Lifting system            

 The STS team also needed to come up with a lifting system and design it, as well as accommodate lifting mechanisms to fit in extremely low-ceiling attic space. STS has also designed and manufactured structures that hold spotlights above the stage and the audience.

“These elements are the essential axis of the project; and it is with their help that we were able to successfully integrate the lighting system. The building is old, the ceilings are uneven, so we have measured the vault of the hall with very advanced equipment to get a very accurate 3D drawing of the vault of the hall, according to which we have designed the metal structures that are used to hold everything,” the Head of STS says.

The spaces under the balconies of the great hall host special lighting devices with good illumination, which at the same time must not dazzle the performers appearing on stage. The entire lighting system is controlled from a special lighting panel. Additionally, certain lighting scenarios are programmed and can be activated from the wall control panel on the stage; and it is also possible to control the entire lighting system remotely from a smartphone or a tablet.

The Lithuanian National Philharmonic Society boasts of a concert lighting system that has no analogues in Lithuania.

The House of Polish Culture in Vilnius

One of the largest Polish institutions in Lithuania aims at organizing the cultural life of the Polish community. The House of Polish Culture in Vilnius (HPCV) focuses on cultural education, support of local artistic and cultural events. Special events, exhibitions, meetings are organized specifically for implementing the activities above.

STS designed and implemented the renovation of the stage lifting mechanisms and drapery systems of the HPCV hall and assembled as well as installed additional equipment for the stage lighting system.

Stage lifting mechanisms

The lifting mechanism system was replaced during the stage mechanization process. The following was installed:

• chain hoists;
• a truss for fastening the lighting system devices;
• a lift control system.

The lifts may be relocated to several different positions depending on the needs of the action onstage. They also comply with the highest safety requirements.

Stage drapery

The works included the renovation of the set of the HPCV stage curtains (coulisses, backdrop). The fabric used is a nonflammable material complying with all of the highest safety requirements. Its colouring matches the space interior.

Furthermore, the stage platform curtain was sewn and set up. It is designed for covering the stage platform if needed, and depending on the nature of the event. It is easy to attach and take off.

Lighting system

STS assembled additional lighting equipment for lighting during the events at the HPCV. A set of programmed lighting devices with a control panel along with cable connection set that allows changing the spotlight positions according to the needs of the event were chosen considering the activities implemented in the House. All lighting fixtures are equipped with modern and durable LED and LED RGBW diodes.

The set also contains a fog machine that helps achieving all stage effects. The set is suitable for creating both concert and theatrical lighting.

Technological installation of the MO Modern Art Museum

The MO Museum that was built in the location of the Cinema “Lietuva” was personally founded by the scientists Danguolė and Viktoras Butkai. Exhibitions, educational activities, concerts, motion picture showings, and other events have been organised here since 18 October 2018. The MO Museum is an exclusive building with universally-adapted areas for different kinds of events or activities (exhibitions, events, conferences, concerts, fashion shows, cinema), and technological systems extensively suitable for all of the above. Their novelty is additionally displayed through a modern concept of functionality.

Stage Technical Service was the main contractor of the technological part of the building. STS designed and installed the following features in this unique building: sound, equipment lifting, lighting, video, and cinema systems.

UNIVERSALITY as the main goal

All systems are distinguished their universality and a large scale of use. The aim worked out from the very beginning – to make all of the spaces of the Museum as universal as possible. Both the managers of the Museum and the contractor together with the architects saw the Museum not only as a single-purpose object – a gallery. This was executed by an advanced and modern attitude of the contractor and the architects, including the invitation to participate in collective meetings regarding the achievable performance capabilities of the building.

BACKGROUND SOUND SYSTEM – one for all spaces

We designed and installed a background sound system that pervades all of the areas of the building, and which could be used to transmit music or informational announcements. What makes the system so practical is the “Symetrix” processor which can be used to control the system via smart devices: tablets, computers, or smartphones connected to a single Wi-Fi network.

Another convenient asset – possibility to divide the zones, 10 in total, and transmit a different or the same content, to set a different sound level, or just to turn off the sound altogether in specific zones.

The following was additionally installed in the Museum:

• echo-acoustic sound systems for exhibitions;
• guide systems;
• audio guides;
• a portable sound system.

INTEGRATIONS BY STS IN DIFFERENT SPACES:

1^st floor LOBBY-HALLWAY

Seven suspension points were installed in addition to the background sound system in the ceilings of the lobby. Lifts for suspending the equipment were affixed on four of the points. The lifts were arranged throughout the perimeter of the space depending on the way the potential activities at the MO Museum will be planned.

An electrical enclosure box with background sound amplifiers and a processor together with lift distribution boxes for connecting and controlling the lifts were set up in the area. The system was installed in such fashion that more than 4 lifts could be set up if needed. This was designed for the sake of making the space as functional as possible for the purposes of the Museum and the organizations preparing for the events, and thus providing an added value to the society.

The lobby can be connected with the universal hall to form an integral space and in this way to be exploited in more functional ways. The background sound system can also be controlled together with the universal hall.

1^st floor UNIVERSAL HALL

This is the most universal and functional space of the MO Museum. It was conceived to be used for various events, conferences, concerts, and a stationary cinema “Pasaka”. Therefore, the aim was to have the technological part designed and set up in this space in such way as to make it convenient for all of the activities carried out.

Sound system was installed to comply with the standards of cinema and concert activities. At the same time it can transmit the background sound and announcements. STS designed and installed the sound system suitable both for cinema and the concerts which was produced by a long-time partner French manufacturer “L-Acoustics”.

The front sound system consists of “L-Acoustics” ARCS WIDE speakers and SB18 low-frequency speakers, while 5XT speakers were installed in the room walls for the cinema purposes (Dolby surround sound). In order to achieve the technological versatility, instead of installing the sound system behind the screen, it was mounted on the outside. Its main clusters are on the sides. 5XT speakers are arranged throughout the perimeter on the walls in compliance with dolby surround sound standard.

Automated curtains were affixed with a view to improve the acoustics of the hall and create a cinema space. They have been mounted in front of the screen, on the glass evacuation doors. Manually-controlled curtains were hung beside the staff and hall exits.

The universal hall has a cinema equipment which can be likewise used for conferences. Both sound and video systems fulfil the specific cinema standard – DCI. A long-term partner of the STS – the BMK company – assisted in implementing all of the video part of the MO Museum project.

A frame screen was set up in the multi-functional hall. If needed, it can be hidden in the recess in the ceiling.

A universal equipment suspension system for suspending additional devices was designed and set up in the hall. This is a truss system moved by electric lifts which can be used for suspending additional sound system, lighting fixtures, other mechanisms, or objects on it. 6 suspension points with slots in the ceiling and connection commutation boxes as well as portable electric lift system were prepared for suspending the equipment.

A lighting system designed for the use of conferences, corporation events was set up in the area. Lighting fixtures were mounted on electric chain hoists that are intended for show business and  suspended on aluminum structures.

Everything was designed and installed so that additional lighting equipment could be suspended if there was a need: additional equipment suspension, connection points were installed specifically for that purpose while the lifts lower the truss down on the floor.

All of these systems are controlled at the control room containing an electric enclosure box with sound amplifiers and lift control panel.

A stage platform of 8×2 meters can be mounted in the space. It is modular and assembled as needed with adjustable size and height.

 1^st floor RESTAURANT

The restaurant had a background sound system integrated which was also installed in the 1^st floor sanitary units. A video projector was assembled in the space for displaying basketball games, concerts, and other kinds of content.

2^nd floor EXHIBITION HALL

STS designed and installed a sound system controlled by zones. The control by zones is practical for adapting the sound as needed should any artistic installations be installed: the sound can be turned off altogether or different soundtracks can be played in any of the hall zones.

3^rd floor EXHIBITION HALL

A special equipment suspension principle was invented and installed in this area in order to set up the suspension points as and where needed throughout the entire span of the hall.

The area also contains a background sound system controlled by zones.

3^rd floor OUTSIDE TERRACE – in future plans

The 3^rd floor will have a coffee shop and an amphitheater outside terrace. It is planned to install technologies that will allow projecting video material on the wall: motion pictures, art, conferences. Furthermore, a sound system acting as a background for the coffee shop or transmitting a cinema signal, conference announcements is also in the agenda.

VIDEO SYSTEMS – in partnership with BMK

The following was installed in the MO Museum:

• digital signage solutions;
• a video wall;
• an interactive screen;
• projection systems with laser projectors;
• a digital cinema video and sound system that can play even the newest encoded motion pictures, and allows using the hall as a cinema.

The video systems are outstanding in terms of versatility and a large scope of use. They were chosen in consideration of the prospect of available activities. All systems are rather easy to control and have a wide range of automation opportunities. There are plans to expand the interactive artistic installations in the future. This can be realized through the DCI system where the interactive control of the content may be accessible not only to the system administrators but the Museum visitors as well.

Šakiai Cultural Centre

Versatility is considered to be a vital factor for the cultural centres that undergo renovations. A perfect example is Šakiai Cultural Centre which has served the local community for 60 years now. In autumn 2018 the Centre was opened once again after 3 years of renovations. The building containing the technical possibilities that make it multifunctional is currently the most modern object of this type in Lithuania and substantially excels the cultural centres of Kaunas, Vilnius, and other cities. The most advanced technologies in the country have been integrated in the Centre.

A rational attitude towards the renovation process and the technological maintenance of the hall became evident throughout the development of the project. The hall moved away from the canonical theatre hall and became a universal hall suitable for any kind of activities implemented by the Centre. Rationality and versatility are also reflected in the equipment assortment – it was bought in optimal quantities, only as much as it was necessary for the activities of the Centre, not to mention it is high-quality and long-lasting.

“Rūdupis” UAB was the contractor of the constructional part of the project while the tasks related to the technological part was completed by “Scenos techninis servisas” UAB.

STS installed the lighting, sound, video, stage drapery, seating, and stage mechanization systems in the concert hall of this cultural building.

Stage mechanization

Completed designs and installations:

• a mechanism for closing-opening the front curtain;
• on stage front lighting bridge of 10 meters with cable collector lifted by chain hoists in the hall;
• lighting soffits with cable collectors lifted by cable hoists with lifting capacity of 1000 kg (3 pcs.);
• decoration lifting mechanisms lifted by cable hoists with lifting capacity of 500 kg (7 pcs.);
• curtain-decoration lifting mechanisms lifted by cable hoists with lifting capacity of 250 kg (3 pcs.);
• additional constructional trusses for suspending the equipment, soffits, and mechanisms.

Stage platform – orchestral pit

The stage platform becomes truly unique and exceptional due to its four functions:

• a stage floor (stage floor extension);
• a choir step;
• an auditorium floor (auditorium extension);
• an orchestral pit (a place for orchestra underneath the stage where it remains invisible to a spectator).

This makes the hall universal.

An additional prefabricated railing is installed when the stage platform is used as an orchestral pit. It is called a segmental wall.

The wall protects from falling in, and fulfills an acoustic function on the orchestral pit – it reflects the sound towards the auditorium. The segments are non-hollow and have acoustic panels.

There is also a sliding staircase on wheels which is designed for climbing on the stage from the auditorium. They can be installed on both sides of the stage.

Stage platforms

The singular and exclusive stage platforms (2 pcs.) can make up the following:

• stage floors (stage floor extensions) to make the hall one integral space;
• amphitheater when the seating system is used in order for the audience to have a better view of the action on stage.

Seating system

Sliding “Figueras” seating systems installed in the main hall fully compensate the elevation angle so a spectator may sit and observe the action on stage both on a flat floor and in an amphitheater regimen.

The system was specifically designed so that an aluminum profile would go across the entire hall in order to slide the chairs or remove them entirely from the hall and leave an open space if needed. They are transferred to a special storage area located at the same level as the hall floors, or they could be brought into the orchestral pit which would lower them down to the storage area underneath the stage.

Šakiai Cultural Centre had the following installations carried out:

• transformation of the auditorium from a flat to an amphitheater floor;
• a sliding seating system;
• a platform which transports the joined chair rows to a storage area.

Sound system

A compact and universal sound system suitable for theatre and concerts was built in the main hall of Šakiai Cultural Centre. It is ARCS Wide and Focus sound system with SB18 low-frequency elements by French manufacturer “L-Acoustics”. It is fully capable of producing pop, rock or lighter music sounds.

The system consists of:

• Wide speakers (2 pcs.), Focus speakers (2 pcs.);
• SB18 low-frequency speakers (2 pcs.);
• “L-Acoustics” amplifiers-signal processors;
• a set of stage microphones together with a built-in wireless microphone system.

Special acoustic materials were used for improving the weak spot of the hall – the acoustics: a set of JOCAVI acoustic panels was installed on the walls for this purpose.

Precise positions for suspending the system and rotation/direction angles were chosen after performing system calculation with a special “Soundvision” software.

Lighting system

Šakiai Cultural Centre has an artistic lighting system set up by applying the aspects of universality and focus on longevity:

• the lighting system was built from quality devices which will remain relevant for many years ahead;
• it was designed and set up in such way so at to add additional lighting elements to the already existing base: panels, completed cabling tasks, affixed cabling channels, control circuits, floor, wall boxes;
• it also has lifting mechanisms, trusses, cable collectors. All of this is ready for when there is a need to add something.

The front lighting bridge located above the audience and suspended on the chain hoists is electrified: it may be lifted up or lowered down. It was designed and set up by applying the high-security factors.

• The hall has a fully set up system of cables and connection boxes for lighting system elements.
• Control and power units were installed up to the intended spotlight mounting spots.
• Control panels were set up in the control room and on stage.
• Floor boxes were integrated on stage and in the hall for connecting additional technological equipment.
• Lighting devices Robe DL4S (5 pcs.), Chauvet Mavericks MK2 Wash (15 pcs.), Chauvet Mavericks MK2 Spot (10 pcs.), Chauvet Owation B-1965FC (4 pcs.), Chauvet Ovation E-260 WW (6 pcs.) were integrated.

Video system

The video system consists of:

• a portable frame screen (10 x 5.7 m) assembled on stage which operates for conference, scenography purposes, compliments the show programs with images, and plays motion pictures;
• it is planned to install a cinema projector with a spatial sound system in the future.

Stage drapery

Front and back curtain opening systems were fully installed on stage.

The coulisse border system covers the sides and the top. Stage drapery is theatrical. It is fireproof, and complies with all safety requirements. Its colouring matches the space interior. The drapery was specifically sewn according to the interior concept.

An ornate front curtain with embroidered coat of arms of the City was custom-sewn for Šakiai Cultural Centre.

Marijampole Cultural Centre

The building location takes up a unique place in the hierarchy of Marijampolė city areas. It is a relevant architectural dominant as well as a valuable cultural centre of the district. The object implements universal activities that emphasizes the importance of the audience hall with 800 seats for the city events. It is like a city square under a roof which provides an area for organizing city management, cultural, business, educational, and entertainment events for the residents. The architecture of the interior and the exterior of the building changes from Postmodernism to Art Nouveau (J. Rėklaitė).

STS performed the stage mechanization, drapery, lighting system renovation tasks.

2017: Renovation of stage mechanisms

The following engineering tasks were completed within the stage: dismantlement of old lifting mechanisms and design as well as installation of square aluminum trusses which were adapted for attaching lighting equipment and decorations. The equipment below was installed onstage:

• five lighting soffits with cable collectors, 14 meters long each, and lifted by chain hoists;
• seven decoration – curtain attachment trusses, 15 meters long each, and hoisted on the lifts.

A front lighting bridge together with a cable collector located above the audience and lifted by chain hoists were newly installed during the renovation.

The trusses were painted black.

Stage lifting mechanisms – lifts.

26 Dutch PROLYTE, PROLYFT chain hoists were installed for this purpose:

• D8 safety class which allows holding the lifted weight above the audience;
• permissible load – 500 kg;
• the set additionally comes with threshold motion sensors;
• stationary mounting under the ceiling and downward release of the chain;
• a control unit with a control panel which has a portable touch screen and controls all lifts together or each separately.

Drapery. The stage drapery (legs, borders, backdrop) was fully replaced during the reconstruction.

Previously the hall had only six legs (three on each side) which did not fulfill their function properly: the audience was able to see the preparing artists, technical staff, and all technical equipment backstage during the performances.

The number of legs was increased twice (six on each side) and some of them were placed vertically to the side walls, others – at a specific angle. The number of borders that cover soffits and decorative rods above was also increased twice.

The backdrop was formed at the same time. Moreover, the stage curtains were used for creating a fully-closed area for performances: technical areas above and on the sides became invisible, allowing the artists or technical staff to carry out the preparatory activities.

The front stage drape was also replaced to an automated one.

Certificates. All lifting mechanisms placed onstage after the reconstruction were checked and had the general user manual issued which indicates the permissible maximum load for lighting soffits or decoration trusses, as well as the frequency of carrying out the safety inspection of the mechanisms.

Furthermore, a special board was made to graphically show how to use the technologies. It is suspended within the stage, in a technical area invisible to the audience. It provides graphic information for the technical staff on permissible loads and their suspension points.

2018: Renovation of lighting system

STS installed the cables and the new electrical enclosure box, connected the power and control cables to the soffits and the front lighting bridge onstage, and set up equipment connection cabinets along with work lighting.

The lighting system is suitable both for theater and concerts, the positions of all spotlights may be changed as needed. All lighting fixtures have LED technology enabling a spectacular illumination of the stage, creation of artistic illumination solutions, and saving the electric power.

A set of new control panels was installed for controlling the fixtures.

A fog machine with fans was set up for implementing the effects of the lighting system.

The lighting system was adapted for transportation and utilization in other areas and outside events. It has a set of storage-transportation boxes specifically for spotlights and control panels.

SEL 25th anniversary tour: unusual stage featuring gigantic robot

In 2017, one of the most successful Lithuanian performers of all times Egidijus Dragūnas and his band celebrated their 25th anniversary. Three concerts were scheduled in the largest cities of Lithuania: Klaipėda, Vilnius and Kaunas, with a spectacular and unprecedented  in Lithuania stage performance, with its central axis being a robot – as high as an 8-storey building, made from different structures, LED screens and visualizations.

According to the concept description, STS designed and installed this unique stage accent and adapted it to two other different locations. Also, in Klaipėda and Vilnius VIP areas were arranged for the guests.

Klaipėda – the base

The first grandiose concert, attended by 19,000 spectators, took place in the Klaipėda Summer Stage. Two challenges were raised for SST. To build:

1. a spectacular unique robotic stage for the musical performance;
2. a two-part VIP platform with a capacity of 500 spectators.

It was publicly announced that during the show, viewers will be able to see a robot as big as a 8-storey house. For the implementation of this concept, STS designed a stage with double roofing, which became the basis for a robot-shaped LED display. The visual of the robot was projected on the screen panels.

A special double-roof structure was built for the structure:

• the higher and narrower roof in the centre of the stage, on which the robot’s head, torso and legs were mounted;
• the broader roof, on which the robot’s chin and shoulders were

The main structure for hanging the robot was also unique: 20.5m high, above which there was 3m moustache with integrated pyrotechnics.

Non-standard structure called for non-standard mounting process: only after the lower roof system and LED screens were installed, the other roof could be mounted. All equipment was brought to the event venue by 5 trucks.

Another challenge was to combine the elegance of the structure with stability and safety. Unconventional idea called for a great deal of equipment. Thanks to STS engineers and the new design program SCIA Engeneer (see the description below), as many as 15 tons could be hung (3 tons of lighting, 7 tons of sound equipment, 5 LEDs) while maintaining security settings.

Next to the stage a two-piece 300sqm VIP platform was built.

Second concert in Vilnius Kalnų Park

Analogical SEL concert was held in Kalnų Park in Vilnius.

Adaptation:

• compensate for the lack of the background (in Klaipėda the platform was built at the Summer Stage, which formed a beautiful background) and to make additional wings from the sides, the same height as the shoulders of the robot.
• evaluate the territory of the Vilnius Kalnų Park, which, unlike Klaipėda, is an open space, and to manage the challenges of the wind; find a compromise between the client’s needs and safety so that the structure could withstand unexpectedly changed wind conditions.
• VIP platform: to level the hill slope and build a platform which could accommodate 300 people.

Final concert – Kaunas Žalgirio Arena

The 2-hours musical show used the same 8-storey-house robotic stage which was transformed into a flying dragon, so a part of the show was performed not only at the main stage but also at the top of the Žalgirio arena.

Here, too, the robot was in the centre of attention. The idea was adapted to the indoor event. The SCIA Engeneer program used by STS engineers was used to adapt the structure and maintain its stability.

SCIA Engeneer – software of the future

To design such an extraordinary stage structure, the special SCIA Engeneer software was used. This future concept is currently gaining more and more popularity around the world.

Building Information Modeling is a revolutionary process of digital design of a building or infrastructure, during which all project-related data is created and managed at all stages, from the initial design concept to its implementation or even disassembly.

The SCIA Engeneer program is exactly that. It combines everything from modeling and analysis, to designing and reporting. This efficient and precise designer-engineer software allows developers to make a complete structural analysis of the object, and to design, calculate and create a 3D model of the project.

The equipment is designed for engineers. It includes a powerful modeling environment, a high-performance network generator, and a very fast finite element solution, as well as integrated tools for checking and optimizing various structures.

In preparation for SEL 25th anniversary tour, the new technology was used by STS specialists to design a non-standard stage, to make its 3D model, calculate load and security, and adapt it to the changing location.

SCIA Engeneer program helped STS engineers to design and implement the following non-standard projects:

• Archbishop T. Matulionis Beatification, 2017 (Lithuania) – extra large roof system: READ MORE
• BlockFest, 2017 (Finland) – modification of a standard stage: READ MORE

Modification of Standard Stage at Blockfest

Blockfest is the largest hip-hop festival in the Nordic countries, taking place in Tampere, Finland, at the end of the summer. Each year, the festival brings together more than 60,000 music fans who want to see the greatest international and local hip-hop artists. The festival of 2017 was anniversary, the 10th, so the organizers were planning to celebrate it as impressively as possible.

STS adapted, designed and installed the stage according to the presented scenography and equipment needs.

Blockfest was planning to build the Prolyte XXL roof, which is the world’s second-largest standardized roofing system (37m wide, 20m high, and 20m deep stage with a rising roof).

In the case of the festival, the stage was non-standard:

• special additional load order from the organizer;
• difficult weather conditions.

Non-standard load and weather conditions

STS engineers had to resolve the untypical situation and get ready for a scenario of 32-ton load on the Prolyte XXL roof system. 32 tons include audio, lighting, video equipment and decorations. Their total weight exceeded the standard capabilities of the roof.

Also, a strong wind was expected both on the date of the event and during the preparation (up to 16m/s). A balance of as much as 53 tons was used to ensure stability of the structure and safety of the participants during the event. To imagine the size of this measure, for comparison, one Mini Cooper weighs around 1 ton, and standard rooftops usually use a balance of about 8-12 tons.

SCIA Engineer – Software of the Future

This special order – a standard stage modified according to expected load and weather conditions – was designed and implemented with the latest SCIA Engeneer software. This future concept is currently gaining more and more popularity around the world.

Building Information Modeling is a revolutionary process of digital design of a building or infrastructure, during which all project-related data is created and managed at all stages, from the initial design concept to its implementation or even disassembly.

The SCIA Engeneer program is exactly that. It combines everything from modeling and analysis, to designing and reporting. This efficient and precise designer-engineer software allows developers to make a complete structural analysis of the object, and to design, calculate and create a 3D model of the project.

The equipment is designed for engineers. It includes a powerful modeling environment, a high-performance network generator, and a very fast finite element solution, as well as integrated tools for checking and optimizing various structures.

This new technology was also used by STS specialists in preparation for the Blockfest festival’s standard stage modification project:

• designing the 3D model,
• calculating load and construction safety,
• roof reinforcement system.

For this purpose, additional columns and BGR 70 trusses, which can withstand extreme load, were used.

To implement the project:

• 2 hoists and a 5m crane were used,
• collaborative work of 14 STS and 8 local professional installers,
• 3 days for assembly.

SCIA Engeneer program helped STS engineers to design and implement the following non-standard projects:

• Archbishop T. Matulionis Beatification, 2017 (Lithuania) – extra large roof system: READ MORE
• SEL, robotic stage for the 25th anniversary concert tour, 2017 (Lithuania): READ MORE

Roof system for T. Matulionis’ beatification ceremony

In June 2017, Archbishop Teofilius Matulionis, who was persecuted by the Soviet government, was announced blessed in Vilnius Cathedral Square. For the first time in the ceremony of beatification held in Lithuania, T. Matulionis was blessed by the Pope Francis’ messenger, Cardinal Angelo Amato. During the historic event which attracted tens of thousands of believers, the Holy Mass was sacrificed in the Cathedral Square on a specially built gigantic roofed stage.

STS designed, manufactured and installed this structure of impressive dimensions – the roof system

ROOF SYSTEM

After the initial design works, it became clear that this would be the largest roof system ever to stand in Lithuania. A specialized Structural Analysis System – a program for designing extremely large buildings – was used.

The specialists of STS have designed this unique stage-pavilion as a temporary and exclusive project. It should be noted that such extreme roof systems are really complicated both in their complexity and technical intricateness, and few companies in the world can implement such a structure.

Roof system specifications:

• 48m width and 24m depth
• 18m (in the same level as the Cathedral roof)
• Roof and sides covered with vertical narrow strips of glossy white fabric to reduce windage of the covered areas.
• The floor was staircased, terraced, and carpeted, intended to seat on the stage several hundred participants of the ceremony.
• During the ceremony, the soldiers of the Honour Guard brought a heavy sarcophagus to the Square through the central door ot the Cathedral. To lift the compact but heavy sarcophagus on stage, a special 16 m length and 6 m width ramp was designed and installed beside the pavilion.
• The soldiers put the sarcophagus on the platform in the middle of the stage.

INSTALLATION

• For the construction of the main pavilion, 1 crane and 1 lorry was used.
• Equipment brought in by 6 trucks.
• Installation process took 4 days.
• Working team: 10 highclimbers, 10 assemblers, 20 additional

SAFETY

The construction of this size requires not only great effort in building it, but also a record level of safety both in designing and constructing it. Such non-standard structures are subject to higher structural and safety requirements than usually.

The installation process was made even more difficult by the weather: the wind was strong, so, with a priority to safety, a huge team worked on the assembly.

DESIGN

To design such an exceptional construction, the special SCIA Engeneer software was used. This future concept is currently gaining more and more popularity around the world.

The special SCIA Engeneer program combines everything from modeling and analysis, to designing and reporting. This efficient and precise designer-engineer software allows developers to make a complete structural analysis of the object, and to design, calculate and create a 3D model of the project.

This new technology was used by STS specialists for designing the roof system, developing its 3D model, calculating loads and safety.

A three-dimensional model was developed, which helped to calculate the strength, stability and decorations of all used structures. This was an unprecedented case, as the software program didn’t include the details used to develop such an unusual structure. First, the software was programmed, and then the project itself.

SCIA Engeneer program helped STS engineers to design and implement the following non-standard projects:

Pavilion LED and Laser Room

In approximately 400m² area, the state of Lithuania and its achievements in the field of energy were presented using laser technologies, laser rays and their imitations, holograms, video material, models and artistic installations. This way to introduce itself as a country was chosen deliberately, as Lithuania is ahead of the world in scientific laser research and manufacturing – every tenth scientific laser in the world has been made in Lithuania.

LED and laser room was a moment of light, energy and speed stopped in an aesthetically pleasing architectural space. The LED room made you feel like standing in the core of a Lithuanian-made laser. It was a phenomenally futuristic experience.

The installation was designed and manufactured in Lithuania by STS. Its creation took:

• 360 LED control channels
• 4km LED strip
• 12km cable
• 1,600 pieces of 3m LED lights specially manufactured by STS
• 5 lasers and a special mirror system
• 5 flashes
• 5 sound patterns

15m width, 8m height and 8m depth room was constructed from special panels with lamps, LED strips and lasers installed in the floor, ceiling and walls, that were hung on metal grids. Mirrors were mounted on the sides. All this created a feeling of infinity.

The installation was designed in such a way that, if a laser ray was cut off (blocked by a person), a specific sound would play, and the flashes would react. This formed the basis for the interactivity, lights symbolizing the birth of a laser.

The laser rays and their imitations were also used on the facade of the pavilion, which was exclusively original and attracted the attention of visitors both day and night.

BLACK SEA ARENA Concert Hall

The new summer concert hall in Ureki resort by the Black Sea in Georgia was a joint project, accomplished by “Scenos techninis servisas” (STS) and “Televizijos ir ryšio sistemos” (TVC). The concert hall is by far the most grand and expensive show venue equipped by Lithuanians.

BLACK SEA ARENA is the largest open concert hall in Caucasus. Designed by German architects, the arena is a unique world-class architectural structure with ambitions to become a powerful center of attraction and lay the foundations for the development of infrastructure and tourism. The arena, which easily accomodates 10 thousand viewers, is a perfect venue for Georgian citizens and guests to enjoy world-class performers, festivals, TV projects and shows. An open roof additionally provides a breathtaking natural spectacle (the Caucasus mountains are visible from the arena), but in case the sun is too active, or it’s too windy or rainy, the roof fully covers the arena in just a few minutes.

STS designed and installed the systems and controls of sound, lighting, stage mechanization, drapery, coating, and special effects, and trained the arena staff.

TVC produced and integrated a television system, consisting of a portable TV station with 24 high-definition broadcast cameras, IPTV network, intercom system, and robotic cameras. The company also carried out the staff training and technical support for the first time broadcast.

Video system was installed in partnership with “Prezentacijų spektras”.

The concert hall has all the necessary equipment for world-class performers so they do not have to rent anything. The sound, lighting, video and TV systems control is fully centralized. Smart hoists help to lift the most complex and difficult structures and allow to move decorations and performers over the viewers’ heads. Audio, video and TV systems are very modern and versatile, and can perform any technical task.

The key challenge and the special feature of this project was the climatic conditions. BLACK SEA ARENA is situated in subtropical climate zone with erratic weather, excessive humidity and salinity. To ensure the smooth operation of all systems and durability of the equipment, the storage system and its exploatation had to be planned precisely. All facility controls are kept in a specially equipped room with extremely powerful autonomous microclimate system, which ensures the stable temperature and humidity.

LIGHTING SYSTEM

Keeping in mind the needs of the concert arena managers, the character of performances and also the climatic conditions, STS professionals designed and installed a mobile and highly versatile large-scale lighting system.

The lighting system consists of various types of spotlights:

• Classical theatrical spotlights (plano convex, fresnel, convex) with incandescent lamps (70 pcs).
• Tracking spotlights with discharge lamps (followspot), which are very powerful, can change colour and adjust diameter of the beam (8 pcs).
• Multifunctional programmable stage lighting devices with discharge lamps (138 pcs), including BMFL, MMX and pointe.
• Multifunctional programmable stage lighting devices with LED light source (224 pcs).
• Powerful calibrated white light floodlights (96 pcs) to go with LED devices.
• Effect lights to supplement basic lighting devices: flashlights, wind turbines with LED backlight, blinders (42 pcs).
• The entire system is controlled by cutting edge software lighting control consoles (4 pcs), two main and two smaller ones. The consoles have been equipped with 16 touchscreens. The entire control system is designed with automatic backup function, so in case of emergency the back panel automatically takes over.

Lighting management system is fully integrated with the video system, so both systems can be operated simultaneosly.

SOUND SYSTEM

The concert hall is equipped with an ultra modern and versatile French L-Acoustics sound system: speakers, monitors, amplifiers, stage sound equipment set (microphones, stands, etc.), and control panels.

The hall’s architecture is highly sound-sensitive thanks to lamella wall structures, movable roof and a huge audience area (80 m deep and 120 m wide). All these features influence the sound, therefore installation of the equipment requires extremely high precision. To have the cleanest and most powerful sound, the sound system must be installed with millimeter accuracy and directed to the target sides of the arena with decimal degree precision.

The sound system was configured in LEFT – CENTER – RIGHT pattern:

• Central array complete with 6 K2 loudspeakers.
• Left and right sides complete with KI-SB with 13 K2 loudspeakers.
• 2 ARCS II loudspeakers for sides of the audience (for viewers on the left and on the right).
• 24 SB28 loudspeakers: 16 suspended and 8 standing.
• 8 ARCS WIDE loudspeakers for viewers sitting close to the stage.
• To enhance loudspeakers volume we installed 32 LA8 amplifiers. 6 of them are mobile, so they can be used on stage. The others are stationary and kept in a room with constant temperature and humidity level.
• Front-of-house audio pannel AVID Venue Profile.
• Stage set: monitoring pannel AVID Venue Profile, 40 wireless and 387 wired microphones, wireless monitoring system. 6 SB18 and 12 KARA loudspeakers. Two types of floor monitors: 16 115XT HiQ passive monitors and 8 112P active monitors.

L-Acoustics sound control system is extremely easy and flexible to use. All devices (sound amplification system, wireless microphone receivers, wireless monitoring transmitters, audio consoles (mixers), processors) can be controlled remotely using a wireless computer network.

STS professionals not only installed the sound system, but also trained the arena staff, teaching them to prepare it for events and make the most of its capabilities. (see DEMO concert below)

INSTALLATION AND STAGE MECHANIZATION

With an impressive amount of equipment – the required equipment was brought to the Black Sea coast by 24 trucks – the assembly started in 2015 summer. Following the STS engineers’ project, first of all, the suspension and service points and cable channels were installed. 52900 meters of cable were laid, 105 electricity and various other connection boxes were assembled.

Bearing in mind the location (subtropical climate zone), the engineering of those boxes was really challenging: they had to be humidity-proof and airtight, yet available for a quick and easy connection of the systems. Equipment control cabinets were installed in a special room with extremely powerful autonomous microclimate system, which ensures stable temperature and humidity.

The stage area is equipped with 12 large cable collectors, each weighing 500 kg. The maingrid consists of 180 meters of extremely heavy trusses. It holds 36 permanently installed hoists with combined lifting power of 72 tons. The maingrid helps to do all the assembly works down on the ground, were it is much more convenient.

According to the needs, the trusses H30V, H40V, S36V or S52SV can be used to equip the stage. These trosses can hold up to 100 ProLyft Aetos lifts with 1000 or 2000 kg capacity. The trusses lifting system consists of 8 Aetos Pro controllers and ProLyft Aetos Piccolo touchscreen control panel. The control system allows to manage all devices simultaneously, e.g., to raise and lower all lifts at the same time.

The arena is also equipped with a crowd control system, which consists of separate Prolyte control barriers. The system is versatile and can be adjusted according to the needs.

STAGE FLOOR AND PLATFORMS

For the stage (the floor, platforms and other elements), we used 1×2 m Prolyte StageDex panels with Easy Frame C, which can change levels and height (1,4-2,1 m). The number of such panels is 452 pcs, they cover 932 square meters. The floor of the stage can be divided into stairs, remade into terraces, islands, audience exits and so on.

There is also a round mobile stage with 6 m diameter.

STAGE CURTAIN

The enormous stage (36 x 24 m) was equipped with a specially designed curtain (drapery). The curtain meets all safety requirements and improves the acoustics of the stage. It was designed to adapt to various hall transformations: from classical theatre events to the most spectacular music shows.

The 20 m high and 40 m wide front curtain was equipped with Showtex automatic opening with variable speed. The design and installation of such a huge curtain was quite a challenge for STS engineers.

Arena has an integrated kabuki system, which helps to cover objects in the stage area (30 m). The system is fully automated and can be managed along with lighting, video, and special effects from the main control panel.

SPECIAL EFFECTS

To improve and intensify the lighting, the system contains a complete set of special effects:

• Fog machines – 8 pcs. The fog helps to enhance the light rays.
• Smoke machines – 4 pcs. Designed to be used in large spaces, they are very powerful and have wheels to move around the stage. Pointed in the right direction, they can fill the entire space of the stage with dense smoke and help create an impressive lighting effect.
• Low smoke machines – 4 pcs. These machines allow to release the smoke along the floor. Can be used to mask the equipment.
• Confetti machines – 4 pcs. Extremely powerful.
• CO2 machines – 8 pcs. Often used in contemporary music events to create a spectacular effect.
• Fire machines – 8 pcs. Smart fire machines can direct the flow of the heat and adjust the diameter, height and colour of the flame.

All these special effects are managed from the main control panel together with lighting, video and other systems.

VIDEO SYSTEM: “Prezentacijų spektras”

The video system was installed  in cooperation with Lithuanian company “Prezentacijų spektras”. It consists of an impressive amount of LED modules, which can be combined into screens of various sizes and shapes.

The essential feature and main task of this system was to integrate video with sound, lighting and TV systems. This required a lot of challenges and extreme professionalism.

LED cabinet specifications: 6.9 mm distance between the bulbs (pitch), 2 K resolution (pixels). High scanning frequency with a large number of colours. Extremely high-resolution of these devices help to transmit really sharp images. The dimensions of one such module is 0.5 x 1 m. All these (660) modules can be connected into 330 square meters display area.

The options how to connect the modules are endless. You can either broadcast pre-recorded visualizations or stream live video of what is happening on stage and in other areas of the arena. You can use separate screens to display different images, or split a single image across all the screens.

The powerful COOLUX  servers help to display extremely real-time signals from the cameras, as well as pre-recorded visualizations.

TV SYSTEM: “Televizijos ir ryšio sistemos” (TVC)

Outside broadcasting station (OBS) and TV system for the arena were designed and built by the general contractor of the project, “Televizijos ir ryšio sistemos” (TVC). The company is an expert in design, manufacture and integration of stationary and mobile TV stations. This outside broadcasting station (OBS) is one of the most modern in Europe and was particularly highly rated in Amsterdam at IBC 2015 exhibition.

OBS consists of two trucks. During broadcasting, engineers, directors, audio and video operators work in the main truck, which is 14 meters long and weighs 28 tons. The truck is equipped with video/audio processing and recording equipment, which transmits live stream from different places, repeats memorable moments, displays subtitles. The OBS truck is equipped with two retractable side mechanisms. This way, as many as 21 operator can work inside during broadcasting.

The second truck is 12 meters long and weighs 24 tons. It is used to transport equipment and generate power (it’s fitted with a 70 kVA generator). Here you can also find the rest and service areas, and cargo compartment with a lift.

Both OBS trucks are suitable for Georgian climate: they are equipped with double air conditioning system, uninterruptible power supply, heating, hydraulic stabilization systems, motorized cable reels.

The TV system has been designed and equipped so as to be mobile and work off-season in other regions of Georgia. Before designing the TV system, three objectives were raised:

• to broadcast live program during the concert on the LED screens over the stage;
• to form live broadcast on other TV channels;
• to create and edit concert recordings, which will be broadcasted later.

OBS has the latest and most professional equipment: ultra high-definition video cameras Ikegami HDK-79GX, including robotic system Ross Video Furio, wireless steadicam, video camera on a winch and ultra high zoom x80 Canon lens. At the “heart” of OBS you will find a powerful  Imagine Communications Matrix with 128 input and 256 output signals. Received video signals are edited real time and broadcasted in the OBS or MCR studio in the arena. The stream received from the cameras can be recorded on servers GV K2 Dyno.

The arena was also equipped with a stationary TV system (IPTV network) for broadcasting other programs.

EQUIPMENT STORAGE

The warehouse was equipped with logistics and warehouse control system between arena and the warehouse, which is located in a different building than arena; equipment preparation and processing areas; the means of storage and transportation of inventory.

Ureki regional climate is complicated, so the warehouse must have a specific microclimate with constant temperature and humidity level. All this was designed by our staff.

STAFF TRAINING

One of the project objectives was to train BLACK SEA ARENA personnel to purposefully use all the new equipment: not just correctly connect the cables, but use all its potential.

STS and TVC professionals trained the staff from the basics. Complex technology requires a lot of specialized knowledge and experience in order to properly master the use of the equipment.

The task was aggravated by the staff’s limited professional experience and language barrier. After the training the arena staff was examined and received training certificates.

THE FIRST DEMO SHOW demonstrates the maximum capability of the systems

The new arena opened on June 17, 2016, with a demo show and concert to demonstrate the full capability of the new equipment and co-ordinated systems which work together and compliment each other.

This precisely to fractions of a second synchronized video, lights and music show required a special stage geometry: 864 square meters of the stage area, stationary and mobile lighting constructions (total 743 meters) equipped with 400 special and 208 multifunctional floodlights, ultra precise sound equipment (64 broadband and low frequency loudspeakers), and 5 high-definition LED screens, covering an impressive 221 square meters at the back. The hidden idea behind the composition was a smile.

CONCERT SERVICE

BLACK SEA ARENA was oficially opened on July 30 with Christina Aguilera concert. The technical rider (sound, lighting, stage and its mechanization) was fulfilled by STS professionals. This also was a part of arena’s staff training.

The video of the concert was arranged by TVC engineering staff.

Coming next: Vanessa Mae, The Scorpions, and the local treasure – Erisioni.

Nemenčinė Multifunctional Cultural Centre

Nemenčinė Multifunctional Cultural Centre educates the community and promotes its cultural and sports activity. The great centre hall hosts major events, concerts and meetings.

Šalčininkai Cultural Centre fosters ethnic culture, amateur art, developes educational art programs and promotes recreational activities, meeting the cultural needs of the regional community.

Renovation works were completed in two stages.

At the first stage, STS installed the stage curtain, video system and lighting soffits. The staff also tested all lifting mechanisms.

At the second stage, sound and lighting systems were installed and cabling works were performed.

While the hall was renovated, STS staff integrated all power and control cables, installed the video system, prepared for remaining installation works.

Finally, the floor cable boxes were installed.

At the first stage, some of the lighting was installed: LED RGBW spotlights, which illuminate the stage and change colors.

Lighting soffits were upgraded to new and lighter aluminum ones.

The hall was equipped with modern cable collectors and electric curtain tracks (14m).

A huge (8x5m) rolled projection screen with a video system serves during conferences and complements the stage set. It can also be used for watching films, turning the concert hall into a mini movie theater.

Dieveniškės Recreation Hall

Dieveniškės recreational hall was renovated in 2013. An old and shabby building completely changed its looks. The main schedule of events consists of traditional festivals, commemorative days, concerts and other activities for the local people.

STS takes interest in renovation and adaptation of community based objects. In the newly renovated hall STS staff designed and installed sound, lighting and video systems, as well as a stage curtain.

The stage sound system was designed to be portable – it takes just 2 people to quickly transform and transport it outside for outdoor events. It is light, acoustically flexible and easily adapted to different spaces. Besides, it was composed of as little components as possible for a fuss-free connection.

The sound kit includes the main sound system, stage monitors, microphones, stands, cables, and a control panel.

The modern lighting system consists of a control panel and RGB color changing LED lights.

The video system is managed from the control panel. The backstage is equipped with an electrified (retractable) 4 meters wide projection screen and a projector, which allows to decorate the space and organize conferences.

The stage looks decorative thanks to the stage curtain kit, designed and installed by STS professionals. The curtain fabric is anti-flammable.

Šeduva Culture and Crafts Centre

Šeduva Culture and Crafts Centre carries out cultural activities, such as rehearsals, performances, concerts, as well as craft activities, such as workshops, seminars, training, conferences and exhibitions.

STS designed and updated the lighting system, performed a partial modernization of the stage mechanisms and installed cables for the stage curtain.

During the renovation of Šeduva Culture and Crafts Centre, new lighting soffits were installed, as well as the stage curtain cables.

Lighting system

The newly installed lighting system consists of classic PAR-type lights, moving heads, regulated and unregulated lighting strips. It is also equipped with a computerized control panel which allows to manage the whole lighting fixture.

Zarasai Cultural Centre

Zarasai Cultural Centre offers the local community a way to express creativity. Cultural centre modernization process was launched back in 2015. The first task was to renovate the recording studio, which was set in the cultural centre basement. 2016 March 1st was an official start of Zarasai Cultural Centre Concert Hall modernization works.

STS mechanized the stage, renovated sound and lighting systems. We also improved the acoustics, changed the seats and newly equipped the recording studio.

Stage Mechanization

First, we provided the lifting gear inspection and decided to renovate them according to the new regulations, which included engineering design works and static-dynamic testing. After that, we  issued new technical passports.

In addition, we installed cable collectors, redesigned lighting soffits, installed an electrified front curtain trail.

The stage drapery was modified to meet the highest safety requirements and is completely non-flammable.

We replaced all 346 seats. Not only they are modern, comfortable and non-flammable, but also add to the natural room acoustics.

Sound system

After analyzing the natural hall acoustic properties and consulting the construction company about suitable renovation materials, we decided to install a linear sound amplification system. The new digital audio console and other sounding system elements ensure a fluent service for all kinds of musical events.

From now on Zarasai Cultural Centre can boast a fully equipped recording studio with quality acoustics, microphones, music software and acoustic panels. Recording room is equipped with Jocavi acoustic panels to record the creations of local songwriters and performers.

The hall is equipped with a classical theatrical lighting system, consisting of profiled spotlights, plano-convexes, Fresnels and flood lights. Ultra-modern, programmable lighting control (Chamsys) and other lighting elements make the stage performances even more enjoyable.

RENDEZ VOUZ Restaurant

In 2016, Lithuanian sprint canoeist and Olympic vice-champion Jevgenij Shuklin together with his friend and businessman Ivan Chomenko opened a restaurant RENDEZ VOUS in their hometown Visaginas.

The owners sought to create a unique environment, which would please clients with the taste for luxury, as well as the ordinary townfolk.

STS designed and installed the sound and lighting systems, as well as the special effects.

The restaurant was equipped with a sound system by QSC, American manufacturer famous for quality, reliability and versatility. The system is versatile – it compiles background music for a special atmosphere and supports live concerts.

The lighting system was integrated into the specially designed interior. The aim was to create a cozy environment for everyday and musical evenings. We decided to install LED floodlights, which fit perfectly into the interior. This type of lighting needs little electricity, has a wide range of colours and can be customized for different types of events.

The restaurant was also supplied with a smoke machine, which helps to create a unique atmosphere for the guests.

Radviliškis Cultural Centre

Radviliškis Cultural Centre is a multifunctional facility with a keen attitude towards modern technologies. It is open to the community, ready to fulfill the needs of self-expressions of its members. The centre is a home for 20 amateur clubs and various communal events.

STS carried out the modernization process of the sound, lighting and video systems, as well as the stage mechanics.

Lighting system

The hall is equipped with a classical theatrical type of lighting, consisting of plano-convex, fresnel and profiled luminaires. This system provides an opportunity to illuminate the entire stage, including the proscenium, in different colours, and highlight every important stage element with spotlights.

Cultural centre is equipped with the lighting control system by Australian manufacturer LSC Lightning Systems, which is maximally adapted to the specificity of theatrical lighting.

Video system

Integrated double-screen projection system with a dual function: the large screen in the back of the stage acts as a decorative set element, while the second screen in the front of the stage serves the conference-type events.

Stage mechanics

STS professionals restored the existing lifting gear, which appeared in almost ideal condition. After changing certain system elements the lifts were successfully tested and received new technical passports.

Additionally, the stage was equipped with a roll-out dance floor.

Sound system and acoustics

After measuring the acoustics of the hall and talking to musicians, a number of acoustic problems were revealed. Also, the natural acoustics had to be balanced, so that performers could sing without any enhancement, but it wouldn’t be too reverberant for pop and rock concerts. STS solved these tasks with the help of EASE acoustic simulator.

The construction company selected appropriate materials and designed the room geometry, so that the entire concert hall could benefit from the smooth, balanced and pleasant sound. The hall was equipped with L-Acoustics KYVA system, which ensures superior sound direction, crucial for natural acoustics.

Radviliškis Cultural Centre staff was trained to use the new equipment and maximize its potential.

Kaišiadorys Cultural Centre

In summer 2015, Kaišiadorys District Municipality signed a contract with STS to carry out reconstruction works of Kaišiadorys Cultural Centre hall. Kaišiadorys Cultural Centre brings together creative and active members of Kaišiadorys community. The centre organizes educational activities and various events, helps local amateur artists, promotes comtemporary culture and professional art.

In 2015, the concert hall was thoroughly modernized. STS professionals updated the sound, lighting and video systems, as well as the stage mechanics.

Sound system

Line array sound system by QSC was installed together with a built-in modern digital control, which opens wide possibilities to control the audio system, adapt it to different performance genres, and provide comfortable work conditions for sound operator. We also provided a complete set of stage equipment (microphones, stands, cables, stage monitors).

Lighting system

The hall was equipped with a modern lighting system, consisting of plano-convexes, fresnels and profiled spotlights, with addition of the latest LED lighting modules (Robe profiles).

Lighting system is now controlled by a digital control panel with touch screens, which enables the lighting artist promptly respond to the changing action and adapt the lighting system to the situation.

Video system

Along with the new lighting system, the hall was equipped with a powerful, high-resolution video projector (Christie) and an electrified movable screen. The system works inline with the lighting system: both complement each other and serve as a part of the set design.

Stage mechanics

STS replaced the lighting soffits (Prolyte Group), repaired the old ones and additionally installed extra lifting gear.

We also designed the layout of the stage curtain and supervised its production (Showtex) and installation. The new non-flammable curtains not only complement the interior of the hall, but also improve the acoustics.

In addition, smoke and fog machines were installed.

Kurhaus of Birštonas

Generally, kurhaus is a resort house with a dancehall and a café. Kurhaus of Birštonas is one of the few surviving buildings of this kind in Lithuania. Built in the middle of 19th century, it was re-opened after the reconstruction in 2013. It’s a perfect location for concerts, conferences and art exhibitions. Kurhaus of Birštonas – the only surviving wooden building of this kind in Lithuania.

Customization of the concert hall and all technical solutions were entrusted to STS professionals.

The stage was equipped with a specially designed lighting system using Robe, Teclumen, Chamsys equipment and L-Acoustics KIVA system. The same system was installed in Birštonas Cultural Centre, so the two systems can be combined to achieve greater visual and audial impact.

Birštonas Cultural Centre

Birštonas Cultural Centre dates back to 1979 and was specifically built as a cultural venue, therefore modernization of its concert hall (2008-2012) required some help from  STS experts.

STS evaluated, designed and implemented modernization of the lighting, sound and stage mechanization systems.

The concert hall, which accommodates up to 510 spectators, has a unique history: it’s a home for international biannual Birštonas Jazz Festival, which is the oldest jazz festival in Lithuania and has been going for more than 35 years. Birštonas Jazz Festival is famous for its diversity of genres and styles: from dixielands to contemporary jazz, the festival explores experimental and innovative trends, brought on stage by Lithuanian and international artists.

Concert hall modernization project was carried out in separate stages (2008-2012):

Lighting system (2008-2009)

Firstly, the spotlights in the galeries and suites were changed to modern profiled and plano-convex ones.

 Secondly, a theatrical lighting system was designed and installed:

– full soffit set for the stage;

– front lighting bridge, essential for this type of stage;

– brand new lighting control system, featuring power and distribution cabinets, control panel, regulated and non-regulated lighting lines.

All these updates were made using highest quality equipment by Robe, Teclumen, LSC Lighting Systems and Lite-Puter.

Sound system (2010)

First of all, STS professionals measured the existing acoustics of the hall. Based on this data, the acoustic project was prepared (using programs Sound Vision and Ease) and the hall was equipped with a sound system by the most professional concert and theatre audio systems manufacturer, the French company L-Acoustics.

We also updated the control panel and installed a complete stage equipment set with microphones, stands, cables, and monitors.

Stage mechanization (2012)

Newly installed automated front stage curtain trail, lifting and lowering mechanism of the front lighting bridge.

Latvian National Museum of Art (LNMM)

Riga is proud to present one of the greatest and most expensive architectural projects of the last decades: the renovated Latvian National Museum of Art. Visitors are welcome to watch all aspects of the museum work process: not just the neatly arranged exhibits, but also the archives, the restoration workshop and the powerful elevator for transporting exhibits.

STS contribution to the new museum was the design, manufacture, assembly, certification and maintenance of the powerful underground ELEVATOR for transporting exhibits.

STS professionals used all their experience to design the elevator and its platform, guide rails, stabilizer frame, management and monitoring of the system and the ability to archive the elevator’s parameters.

The high speed elevator (platform size 12.0 x 3.4m) consists of four individual lifting mechanisms that operate simultaniously to lift the platform with the maximum of 40 tons of cargo up to 10 centimeters per second.

The elevator, which is 9 meters deep, is open on the top and transparent inside, therefore completely visible to the onlookers. The glass opening serves as a light source, and is compatible with the updated building concept – to make all processes visible to the visitors of the museum.

Particular attention was paid to security – the elevator is equipped with dual brake system. The smooth control of the process (the speed, load, position and other parameters) is ensured by the control panel, which is monitored in real time by STS team in Lithuania.

The entire lifting system is installed in field conditions. Platform lifts are made of non-corrosive materials, coated with a special protective coating used in the North Sea oil platforms. The elevator is equipped with automatic systems to protect the facilities against flooding.

The foundations of Riga’s museum building are constantly rinsed with groundwater, so the STS designers were brought to a challenging task: to accommodate the lifting mechanisms in two times lower height than the height Swiss engineers had allowed in the original renovation project.

As a result, all lifting mechanisms were designed and installed extremely compactly. Using Serapid lifts, the STS team packed the whole elevator system in 1 meter deep pit.

ADDITIONALLY the museum was equipped with electrified curtain and roller systems, lighting and sound systems.

Palanga Concert Hall

Reconstruction of Palanga Summer Stage into the Concert Hall

Palanga Concert Hall is one of the largest new Lithuanian cultural objects. The technical part of the hall was designed and installed by STS. The hall was equipped with highly advanced systems: electro-acoustic system, orchestra pit and its automatic lifting and lowering system, upper stage lifting mechanisms, stage curtains.

Technological distinction of Palanga Concert Hall lies in the powerful electro-acoustic system and the moveable orchestra pit, which transforms the stage and the audience space. These are the main means to maximally quickly transform the 2,200 seat hall for a new event and to meet the requirements of any performer.

The digitized high-tech electro-acoustic system, which has no analogs in the Baltic region, is adapted to different music genres. It’s an extremely complex professional system, which adapts acoustic sound of the hall to the music performed on stage (with 15 pre-programmed musical settings, from wind instruments, theater and ballet, to cathedral choral singing and other musical genres).

Electro-acoustic system acts as an addition to the natural acoustics, complementing it, but not overwhelming. Processors perform millions of mathematical calculations to analyze real-time room acoustics and add any required acoustic elements. The audience hears the final result through 112 L-Acoustics loudspeakers. This way the hall acoustics maximally convey the action happening on stage. Mechanisms located above the stage and the audience help quickly set up lighting, audio and video systems.

The movable orchestra pit platform, designed and installed by STS engineers, was assembled from separate parts, connected by screw joints. This solution was found after it became clear that to bring 64 square meters of the podium into the hall is an impossible task. Non-standard, curved orchestra pit is unique: it can be fixed in several positions to extend the pit or seating area, or to become the part of the stage.
