A self-contained remote control unit for use on electronic equipment processing on audio output such as home entertainment equipment (i.e. a television receiver, whether black and white or color, an AM radio, an FM radio, an AM/FM radio, or an audio magnetic tape player) comprises an externally mounted remote control receiver which connects to the home entertainment equipment through the earphone connector of said equipment and thereby disables the speakers of said equipment. The remote control receiver unit includes its own speaker which replaces the disabled internal speaker of the equipment to be controlled, a programmable audio power amplifier for driving its speaker, and an on/off triac which supplies AC power to the equipment to be controlled when said equipment's AC power cable is connected to an AC receptacle on the receiver. A battery-operated, hand-held, hand-operated remote control transmitter is used to send wireless information to the remote control receiver. The remote control transmitter unit includes a keyboard, a remote control encoder, and an output circuit.
