SPEAKER CIRCUIT
CIRCUIT DESCRIPTION
The sound signal that has been amplified by the stereo component amplifier assy is sent to the speakers
from the stereo component amplifier assy through this circuit.
If there is a short in this circuit, the stereo component amplifier assy detects it and stops output to the speak-
ers. Thus sound cannot be heard from the speakers even if there is no malfunction in the stereo component
amplifier assy or speakers.
When a short is detected in the speaker circuit, no sound can be heard from the speakers.
