LE GRAND T
Company: DTS Location: Nantes, France
Le Grand T is an iconic theatre in the Nantes area of France, which collaborates with many cultural organisations. In addition to a large hall, the building houses a restaurant and a library.
ESL was entrusted with the task of installing a completely new lighting system in the theatre to replace the old incandescent lamps, allowing better space management, as well as the capacity to manage each fixture and different colour temperatures. The company designed and delivered a large network made up of DTS TITAN LED projectors that significantly reduced power consumption and improve light quality. ESL’s Jerome Van Dyk, in partnership with DTS’s Andrea Gabrielli, answered a brief set by François Guillet of Lumières Utiles. Requests were made in accordance with French public market laws. The installation was carried out by Forclum company. To answer the brief, ESL prescribed custom DTS TITAN LED fixtures, with 48 LEDs (24 amber, 12 white 3200°K and 12 white 4500°K), with separate low voltage PSU. Internal software has been modified to offer simple menus, and custom DMX512
functions, to allow even smoother dimming, especially in the 0-20% range. Barndoor and filter frame (to allow the use of Holographic filter) were also added. The realisa- tion of prototypes has been incredibly fast, which has clearly benefited the project. In total, 130 fixtures were installed in five lines across the ceiling. Light can be controlled through the ETC ACN network with AVAB light desk, with small 6-channel desks controlling groups and presets on a Pharos LPC1 controller, through a web interface including Ethernet distant access. Fixtures can be individually controlled in a matrix.
The new system has resulted in an even diffusion of light over the seats, an easily manageable colour temperature range between 2800°K and 6000°K. Other posi- tives include: virtually zero-maintenance due to LEDs’ long life span, energy saving and more flexibility of control.

NAGY LÁSZLÓ
Company: QSC Location: Ajka, Hungary
QSC’s Hungarian distributor, Interton, has supervised a major sound system instal- lation as part of a complete cultural centre rebuild in the city of Ajka. Located in the north-west of the country, the local government-run Nagy László Cultural Center has been re-equipped with an end-to-end QSC solution, including an Installation Line Array (ILA) system.
Interton has a long relationship with the venue’s Acoustic Consultant, András Kotschy, who specified QSC components in the tender. “Due to our good relationship with the main contractor we managed to win the supply of the equipment - and the installation works as well,” confirmed Interton MD, Géza Balogh. The scope of the contract included the commissioning of a new sound reinforcement system for the main auditorium, as well as the intercom system. The ILA not only had to demonstrate its extraordinary horizontal coverage (140°) but also its abil- ity to satisfy the requirements of a multipurpose venue that would stage concerts, theatrical and ballet performances. “In other words, we had to provide the technical backbone for a number of different events,” said Balogh. The system also had to project across the raked, 422-seat main auditorium floor, as well as deliver evenly distributed sound to a further 53 in the first floor gallery. Having won the contract, Interton Project Manager Zoltán Fleischer sat down with the consultant and discussed the operational requirement in detail. The evolved solution was to specify a QSC SC28 2-in / 8-out user-configurable digital system, containing dedicated pre-programmed tunings, to drive the PA system (in triamp plus sub mode) through a pair of QSC RMX5050HD and three RMX2450 amplifiers. To achieve the coverage, Interton installed six WL2082-i mid-highs and a single WL118-sw subwoofer per side, using the recommended settings (other than the EQ compensation, which was not required). Each element contains two 8-inch neodym- ium magnet woofers and 1.75-inch neodymium compression drivers with titanium dome HF.
Sound sources include Sennheiser and Shure wireless microphones, Shure and

AKG wired mics, which can be connected to the stage boxes, along with Tascam CD recorders and MD player. The left and right hangs are fed from the outputs of the mixing console.
The client was more than satisfied with the overall sound quality and particularly the evenly dispersed coverage across all the seating. In fact one famous Hungarian rock band, encountered the six powered QSC 2-way 12-inch K12 speakers - which were being deployed as stage monitors - for the first time, and immediately remarked on the excellent features and sound quality. The K12’s, which contain 1kW of continu- ous class D power, can also be used as a portable PA system to provide the venue with additional flexibility.
Géza Balogh said: “The ease of programming the SC28 speaker processor demon- strated how user-friendly it is, and made fine tuning the FOH installation simple and straightforward.”
