San Luis Obispo, CA (September 7, 2005)–San Luis Obispo County’s government recently moved into a newly built administration building. A project five years in the making, the building was designed with an aim to be cutting edge, and that included the facility’s audio/visual and information technology, according to Joey D’Angelo, principal consultant with Charles M. Salter Associates, Inc., the San Francisco-based consulting firm who designed the facility’s A/V system. Key to the system, he reported, is a SymNet Audio Matrix from Symetrix.
“Much of the project’s architecture and A/V system design changed over the years, but the recognition of the need for the system to work as hands-off as possible stayed steady,” said D’Angelo. That goal was reached by pairing a Crestron 2 control system with SymNet’s modular audio processing hardware. This allowed D’Angelo the freedom to design a comprehensive audio routing and processing system that could easily be changed via touch screens to suit the nature of the various proceedings in the Board of Supervisors Chambers.
A total of five SymNet 8×8 DSP units form the backbone of the audio system. They are responsible for massaging and directing audio traffic in a network that incorporates 36 inputs and 28 outputs. “It’s a huge system as it’s set up now, and it’s very complex given that it’s a hybrid system that’s part stand-alone A/V and part broadcast-capable,” D’Angelo described. “SymNet comes in very handy in making it all happen.”
The system requirements were formidable. It would have to handle 21 microphones, numerous audio and audio/visual sources–some requiring playback and archive capabilities–while delivering separate feeds for CATV broadcasts and nine reinforcement zones. SymNet handles mixing, dynamics, equalization, routing, delay, and level control for multi-zone speech and playback reinforcement in the venue. It also interfaces with a number of outboard devices handling various archive, broadcast and production tasks.
Hosting not only the county’s main governing body, but numerous other state and local governmental panels, the new chambers are currently in use four days a week, according to Greg McDougall, a member of the county’s A/V staff.
