AUDIO / VISUAL AUDIO AND VISUAL SYSTEM

1 AUDIO / VISUA AUDIO AND VISUA SSTEM 9 Speaker Circuit DESCIPTION Sound signals that have been amplified by the stereo component amplifier or radio receiver assembly (built-in amp) are sent to the speakers from the stereo component amplifier assembly or radio receiver assembly through this circuit. If there is a short in this circuit, the stereo component amplifier assembly detects it and stops the output to the speakers. Thus sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly or speakers.
