PRINCIPLES OF OPERATION

The audio control unit can be powered up when the key is in the ON or ACC position. The audio control unit provides audio signals to the speakers, thus producing sound.

The audio control unit directs the audio signals to the speakers through separate positive and negative circuits for up to 4 audio channels (depending on configuration): LH front, RH front, LH rear and RH rear. The audio control unit provides internal circuit protection for shorts to ground, shorts to voltage or shorts between any output circuits.

The radio suppression equipment reduces interference transmitted through the speakers by the engine ignition and electrical systems.
