ーのミユーテイング回路。 In a tape recorder in which a first tape recorder having at least a playback function and a second tape recorder having a recording and playback function are built into the same cabinet, the signal played by the first tape recorder and the second tape recorder an output terminal to which a monitor signal of the reproduced signal and the signal recorded by the second tape recorder is output; a muting transistor which bypasses the signal output to the output terminal when in a conductive state; and when the power is turned on; a control transistor that becomes conductive during a muting operation and makes the mutating transistor conductive, a first switch that is opened when the first tape recorder is in a playback state, and a second tape recorder that is in a recording and playback state. The second one will be released at some point.
A tape recorder comprising: a switch; and a switching transistor whose operation is controlled by the first switch and the second switch, and which becomes conductive when at least one of the switches is in an open state, and makes the control transistor non-conductive. Muting circuit.
