路。A first input terminal for inputting an audio signal, a second input terminal for inputting a playback signal from the playback head, and a second input terminal for receiving operation commands from the outside are different between playback mode and E-E mode. a controller that derives command signals having first and second levels; an output terminal that selectively derives the audio signal or the playback signal; and a controller that receives the command signal and outputs the command signal from the first level to the second level. a circuit that generates a switching signal that extends the transition time; and a circuit that is controlled by the switching signal to output the reproduced signal from the second input terminal when the switching signal is higher than the second level, and output the reproduced signal from the second input terminal when the switching signal is higher than the first level. An audio signal mute circuit comprising a switch circuit that operates to apply an audio signal from one input terminal to each output terminal,
The switching signal generation circuit is configured to generate signals from the first to second level.
An audio signal mute circuit characterized in that it creates a switching signal whose waveform leading to a level is step-like.
