AUDIO AND VISUAL SYSTEM DVD Sound Signal Circuit between Radio Receiver and Stereo Component Amplifier

DESCRIPTION

The radio receiver sends only DVD sound signal to the stereo component amplifier through this circuit.

The sound signal that has been sent is amplified by the stereo component amplifier, and then is sent to the speakers.

If there is an open or short in the circuit, only DVD sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier or speakers.
