ABSTRACT:
A system for wirelessly transmitting stereo audio from a source such as a tape player to a removed location. The output signal-carrying wires from the source are connected to a coupler unit adapted to removably hold an FM band stereo broadcast microphone/transmitter. The audio output signal is coupled to the microphone/transmitter which, in turn, transmits the audio signal to an FM stereo receiver at the remote location where it is then rebroadcast for listening. In one embodiment, the coupler unit acoustically couples the signal to the microphone. In a second embodiment, the coupler unit inductively couples the signal to the microphone.
