A device comprised of separate transmitter and receiver sections, which converts an audio signal into an FM signal, transmits the FM signal over AC power lines, and reconverts the FM signal into an audio signal, which can then be outputted to loudspeakers or other devices. By transmitting the signal over AC lines, no long wires are needed to connect remote loudspeakers or other devices to the source of the audio signal.
