The City Cultural Centre's sound reinforcement is divided into five independent sound distribution zones. The largest of these is a 300-seat auditorium, which is also utilized as a cinema.
"Multifunctional rooms create numerous challenges," says Krzysztof Goslinski, construction manager at BGR. "They require a combination of high intelligibility, homogenous sound and powerful coverage." Additionally, the customer wanted to integrate the old into the new sound reinforcement system and planned to use the auditorium's system in different locations. "The biggest challenge was to create an easy-to-use system that would sound great, regardless of the application," adds Goslinski.
A highly versatile sound reinforcement system was therefore required. The ideal set-up proved to be a main system consisting of six Dynacord Cobra-4-Far, four Cobra-4-Top and three SUB 28 subwoofers. Two Dynacord VariLine VL 262 speakers serve as front-fills while five VL62 speakers are installed as delay lines. Eight Dynacord CXM 15 monitors provide sound reinforcement on stage.
"The Cobra-4 system is incredibly versatile and provides great sound, no matter what kind of event takes place," says Piotr Wosiek, the head of Tommex's Olsztyn office, the company responsible for delivery and startup of the sound system. "At the same time it can be easily dismantled and used at another location. In such a case, six Dynacord VL212 loudspeakers will take over in the auditorium. "To avoid disassembling the subwoofer section, eight further SUB 28 subwoofers provide sound reinforcement for the Cobra system when used as a mobile system.
All loudspeakers and monitors inside the auditorium are powered by a combination of Dynacord LX and DSA series amplifiers with remote control modules. For signal control, the centre relies on two Dynacord DSP 600 digital sound system processors, a P 64 digital audio matrix manager and IRIS-Net software.
During the course of the modernization, additional rooms at the City Cultural Centre were also given a facelift. A total of 20 Dynacord D-LITE and A-Line loudspeakers now provide sound reinforcement for another multifunctional room, an art gallery, a dance room and the centre's café. An installed CMS 600-3 mixer and an SL1200 amp extend the possible uses of the multifunctional room, while a PM 502 mixer allows user-friendly operation of the sound systems in the other rooms.
