The left and right channel stereo signals are input to the left and right mixing amplifiers, and the output signals of the left and right channel external inputs are input to the left and right mixing amplifiers together with the stereo signal through resistors, respectively. A mixing mode selection circuit is inserted between the resistor and the input terminal of the right channel resistor, or between the left and right channels in the stage preceding the input terminal, and the impedance between the output terminals of the resistor is increased when viewed from the stereo signal side.
