Hungarian cultural centre upgrades with QSC

12 October 2010

Hungary - Hungarian audio distributor, Interton, has supervised a major sound system installation 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 Centre 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 [Csöngeto Ltd.] we managed to win the supply of the equipment - and the installation works as well," stated 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 ability 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 through a pair of QSC's RMX-5050HD 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 neodymium magnet woofers and 1.75" 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.

Summing up, Géza Balogh said, "The ease of programming the SC28 speaker processor demonstrated how user-friendly it is, and made fine tuning the FOH installation simple and straightforward."
