Buttenheim, Germany (September 9, 2005)–The Zentrum Paul Klee in Bern, Switzerland, a museum, concert hall, theater and convention center dedicated to the Swiss artist, musician, pedagogue and poet, has installed an extensive Nexus audio network by Salzbrenner Stagetec Mediagroup. The system interconnects the control rooms of the auditorium and forum stages, provides signal routing within the entire building complex and feeds the sound reinforcement systems.
Erwin Schenk, the head of the Zentrum’s multimedia technical section, opted for a combination of a Nexus audio routing system with a Yamaha DM2000 and a Yamaha DM1000 console. Instead of the Yamaha microphone pre-amplifiers and A/D converters of the consoles, Schenk also wanted to use the 28-bit Nexus TrueMatch converters, which convert the microphone signal directly, without pre-amplification, into the digital domain. Eliminating noisy analog preamps, this approach also enhances routing flexibility.
Specifically for that application, Stagetec designed a control interface that emulates the proprietary Yamaha protocol, so that the Nexus XMAD boards can now be controlled from the third-party console. The interface was implemented over the RS422 control line of a Nexus XCI control-interface board, allowing the engineer to change the parameters of the Nexus microphone input board, such as gain or subsonic filter, through the controls of the console.
The Zentrum Paul Klee uses a setup comprising six Nexus base devices, located in two control rooms, at the stage and the gallery with the remaining two used as mobile units to be placed wherever I/O ports are required. These mobile devices are also equipped with XMAD and XCI boards, enabling the possibility to integration with the consoles and the microphone input remote control.
