Mute Signal Circuit between Radio Receiver and Stereo Component Amplifier
DESCRIPTION This circuit sends a signal to the stereo component amplifier assembly to mute 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 speakers when changing the sound source. If there is a sho ...
