<p>An audio distribution system includes a main control unit for distributing audio signals to a plurality of zones using a remote programming unit and a plurality of zone input panels for commanding the types of audio signals to be routed to the various zones. The remote programming unit includes a plurality of input switches, and a command sending circuit responsive to the input switches for sending a command selected by the switches to control the audio in a selected one of the zones. Each of the zone input panels includes a receiver for receiving the commands from the remote programming unit. The receiver is used to couple the received command to the main control unit. The main control unit receives the command from the zone input panel and controls the audio for the selected zone independently from the other zones.</p> |
