Why choose the CSP-428
It handles processing and routing for the room, so microphones, speakers and sources are managed on one Bose platform. Corporate AV checks the room, mounting surface, power and network during a site survey, so the CSP-428 is installed and commissioned as part of a complete AV system rather than delivered as a box.
