オテープレコーダーの入力回路。In a stereo tape recorder equipped with built-in microphones for left and right channels and an external microphone jack, conduction is established through one of the external microphone jacks to a common line that supplies operating power supply voltage to each of the built-in microphones. By connecting a switching transistor and inserting an external microphone into one of the external microphone jacks, the switching transistor is rendered non-conductive and at the same time, the external microphone input signal is input to the amplifier of the corresponding channel.
