In apparatus for switching between recording (REC) and playback (PB) modes of a tape recorder (14) having a single input/output jack (15) compatible with two channels to which an output plug (21) for an earphone or headphone (20), or an input plug (19) for a microphone (18) can be connected, when a remote control unit (16) having a remote-control switch (27) and connected to an input/output transducer (28) is connected to the jack (15), one channel is used as an input channel for a remote-control signal, and the other channel is used as an input/output channel for an audio signal. The tape recorder (14) may have a control circuit for discriminating between insertion of a 1-channel plug and insertion of a 2-channel plug into the jack (15) to control the operation of a switch (23) in the tape recorder (14). |
