入力信号切換回路。 At least an equalizer amplifier that amplifies the tape playback signal, a microphone amplifier that amplifies the microphone input signal, an external input signal input system that inputs the external input signal,
A preamplifier, a recording amplifier, and a logic control circuit are integrated, and the output of the logic control circuit turns on the equalizer amplifier and preamplifier when reproducing the signal input to the external signal input system or the tape signal. At the same time, the microphone amplifier and recording amplifier are turned off, and when recording the signal input to the external signal input system or the tape signal, the equalizer amplifier is turned off and the microphone amplifier, preamplifier, and recording amplifier are turned on. An input signal switching circuit for a tape recorder, characterized in that it is controlled.
