。The first terminal from the first and second input terminals to the first and second speakers.
In a stereo/monaural switching circuit that connects a switch between the second audio signal path and turns the switch off when receiving stereo and on when receiving monaural, the base is connected to the input terminal and the emitter is connected to the speaker side. A first switch connecting the first and second signal paths is connected at a point after the emitter follower, and the first switch is connected to the second signal path. A second switch is inserted between the point supplied to the signal path and the output end of the emitter follower of the second signal path.During stereo reception, the first switch is turned off and the second switch is turned on.During monaural reception, the first switch is inserted. A stereo/monaural switching circuit characterized in that a switch is turned on and a second switch is turned off.
