QSC in cultural centre overhaul

Interton, a Hungarian audio distributor, has overhauled sound at a cultural centre in Ajka. The Nagy Lászlo Cultural Center has been equipped with a QSC solution, including an Installation Line Array (ILA) system.

The centre is located in the north-west of the country and is run by the local government. The venue’s acoustic consultant, András Kotschy, specified QSC components in the tender. “Due to our good relationship with the main contractor [Csöngető Ltd.] we managed to win the supply of the equipment — and the installation works as well,” said 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 had 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’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.

Balogh concluded: “The ease of programming the SC28 speaker processor demonstrated how user-friendly it is, and made fine tuning the FOH installation simple and straightforward.”
