ダのミューティング回路。A first power source that provides a high potential, a second power source that provides a low potential, and a switching voltage that is applied from the first power source or the second power source through the recording side contact of the recording and playback switch. In order to enable muting of the system, a switching element whose reference potential point is connected to an intermediate potential point between the first power source and the second power source, and a bias from the first power source or the second power source is used. Muting of a tape recorder, which enables recording by applying a voltage, and is equipped with a built-in microphone whose reference potential point is connected to the second power source or the first power source. circuit.
