とするマイク入力回路。The output of the pre-amplifier and the input of the post-amplifier are connected through a switch S1 for switching the signal source, and when the tape recorder is in recording mode, the microphone input signal passes through the switch S1 and the recording/playback switch S2 and is sent to the pre-amplifier. When the tape recorder is in a playback operation state, TV audio reception state, radio audio recording state, etc., the microphone input signal passes through the switch S1 and the pre-recording/re-recording switch S2 and is input to the post-stage amplifier.
