Speed Signal Circuit (Stereo Component Amplifier Assy)

SPEED SIGNAL CIRCUIT (STEREO COMPONENT AMPLIFIER ASSY)

CIRCUIT DESCRIPTION

This circuit is necessary for the stereo component amplifier assy for the ASL (Auto Sound Leveliser). Speed signals are received from the combination meter.

The ASL function automatically adjusts the sound data in order to enable to hear the clear audio sound even when the vehicle noise is increased (as vehicle noise increased, the volume is turned up etc.)

Standard System: Using speed signals and a microphone for the ASL built into the stereo component amplifier assy.

Mark Levinson System: Using speed signals.
