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

for Preparation Click here


DESCRIPTION

The radio receiver sends a 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, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier or speakers.

    		Below 1 Ω
    L- - L-
    		Always
    		Below 1 Ω
    R+ - R+
    		Always
    		Below 1 Ω
    R- - R-
    		Always
    		Below 1 Ω
    SLD - SLD or SGND
    		Always
    		Below 1 Ω
    L+ - Body ground
    		Always
    		10 kΩ or higher
    L- - Body ground
    		Always
    		10 kΩ or higher
    R+ - Body ground
    		Always
    		10 kΩ or higher
    R- - Body ground
    		Always
    		10 kΩ or higher
    SLD - Body ground
    		Always
    		10 kΩ or higher



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK
