AMP Mute Signal Circuit (From Radio Receiver Assembly)

AMP SOUND SIGNAL CIRCUIT (FROM RADIO RECEIVER ASSY)

CIRCUIT DESCRIPTION
This circuit sends a signal to the stereo component amplifier to mute noise. Because of that, 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 assy is normal, no sound or only extremely small sound can be produced.
