Mute Signal Circuit between Radio Receiver and Stereo Component Amplifier: Description

This circuit sends a signal to the stereo component amplifier to mute the noise. Because of that, the noise produced by changing the sound source ceases.

If there is an open in the circuit, noise can be heard from the speaker when changing the sound source. If there is a short in the circuit, even though the stereo component amplifier is normal, no sound or only extremely small sound can be produced.
