Bern town hall in Switzerland has recently had two steerable Meyer Sound CAL 64 column array loudspeakers installed.
The system has been implemented in the Grossratssaal, the main legislative chamber within the 15th century Gothic building.
Daniel Zurwerra of Switzerland-based Virtually Audio managed the project. “Voice reinforcement in this space is challenging for several reasons,” explains Zurwerra.
“First, the reverberation time is more than two seconds, and even higher at some frequencies. We have high background noise levels, and because of aesthetics and historic preservation requirements, loudspeaker placement and positioning is highly restricted. It was clear that beam-steering columns would offer the best results.”
“When choosing CAL, I considered the accuracy of simulation data, dedicated drivers for LF and HF, a digital audio network interface, relay closures for fault reports, and options for custom colors and mounting. In addition, I knew I could count on strong local support for Meyer Sound products,” adds Zurwerra.
The new audio system for the Grossratssaal also features a Biamp Nexia CS digital signal processor, a Brähler conference system, Shure wireless microphones, and an AMX control system.
