A remote control apparatus is provided for a record/playback device to provide control signals to actuate the device for recording, for playing back or retrieving, and for reversing or rewinding operations. The control signals are derived from separate switches and transmitted along a single signal conductor. A logic circuit responds to the signals on the single conductor to activate different output lines selectively for the different operations. The record/playback device typically is of the type that records and plays back audio information, or that records and projects visual information.
