CA 2283577

A remote-controlled audio system comprises several sets of loudspeakers (14A - 14D) connected to a corresponding number of power amplifier units (22A - 22D)in an audio distribution unit (10) to which several audio sources, such as a compact disc unit, a tape deck, and so on, are connected. Each power amplifier unit has a pair of power amplifiers, each connected to one of the loudspeakers in the set. The pair of power amplifiers are referenced to a reference ground (1) and a second ground (2), respectively. The second ground (2) is maintained at a prescribed voltage relative to the reference ground. A remote unit (34A) is connected between the respective "ground" terminals of the two loudspeakers of the set, i.e. those connected via the speaker cables to the first and second grounds in the audio distribution unit. The remote unit has a transmitter unit for transmitting control signals to the audio distribution unit via the loudspeaker "ground" cables. In the audio distribution unit, an interface circuit connected between the first and second grounds includes a receiver for receiving the control signals and conveying them to a control device which adjusts the settings of the audio distribution unit in dependence thereupon. The remote units may receive power from the audio distribution unit via the transmission channel to supply their internal components.
