This is a stereo recording input circuit in which an external microphone input terminal and an auxiliary input terminal are connected to the input side of the amplifier of each channel, and a single built-in microphone is commonly connected to the input side of each amplifier via a resistor. A switch is provided that turns on a switching transistor so as to cut off the operating power of the built-in microphone and simultaneously ground a common output terminal of the built-in microphone when an external microphone input or auxiliary input is applied to the external microphone input terminal or the auxiliary input terminal. A stereo recording input circuit.
