    Abstract: A master transmitter distributes a plurality of audio channels to one or more expansion receivers as a multiplexed audio stream. Control information is also transmitted between the master transmitter and the expansion receivers. Both the control information and the multiplexed audio stream are transmitted on the same cable allowing for reduced clutter and cheaper material and installation costs.
