Abstract
A proportional audio power demand system has a plurality of speaker banks and a plurality of amplifiers. Each speaker bank has at least one speaker. The system also has at least one audio channel and each amplifier and speaker bank can be selectively coupled to the audio channel. The system includes a controller which causes at least one amplifier and speaker bank to be coupled to the channel. The system also includes a sensor which senses the power output of the amplifier. The sensor is coupled to the amplifier and controller and the controller responds to the sensed power output of the amplifier to determine when to cause an additional amplifier to be coupled to the channel.
