Abstract
A multiport bridge controlled by the intelligence of a programmed microcontroller selectively channels audio from a plurality of input ports to a plurality of output ports including a room program output. Coupled to one of the bridge input ports is at least one gated microphone mixer, including multiple microphone channels and an acoustical echo canceller. Expandability is provided by a second, third or up to n microphone mixers each having a separate echo canceller for the associated group of microphone inputs.
