In the duplex tape recorder which can take a first recording state in which the sound is recorded and a second recording state in which the playback signal reproduced by the second tape recorder section is recorded, a connection between the base of the transistor and the power supply path is provided. A thyristor is connected in the forward direction in between, and the second
A detection signal for detecting the playback state of the tape recorder unit is applied as a trigger voltage to the gate of the thyristor, and in the first recording state, the second tape recorder unit is set to the playback state and the detection signal is applied to the gate of the thyristor. When the playback signal from the second tape recorder section is supplied to the first tape recorder section, the detection signal from the second tape recorder section causes the thyristor to conduct, thereby supplying power to the base of the transistor. A dual tape recorder characterized in that the transistor is turned off to cut off the supply of power supply voltage to the microphone.
