AUDIO AND VISUAL SYSTEM (for Radio and Display Type) Speaker Circuit

DESCRIPTION


The sound signals amplified by the radio and display receiver assembly*1 or stereo component amplifier assembly*2 are sent to the speakers from the radio and display receiver assembly*1 or stereo component amplifier assembly*2 via the speaker circuit.

If there is a short in a speaker circuit, the radio and display receiver assembly*1 or stereo component amplifier assembly*2 detects it and stops output to the speakers.

Thus sound cannot be heard from the speakers even if there is not a malfunction in the radio and display receiver assembly*1 or stereo component amplifier assembly*2 or speakers.
