Automatic Volume Control (High Line System Only)
Automatic volume control (High line system only)
An automatic base and treble volume control feature compensates for increases in interior road/transmission noise. A road speed signal is monitored by the power amplifier, the signal is supplied by the SLABS ECU.
The power amplifier boosts the levels of base and treble as road speed increases. This system ensures that the apparent volume of sound remains constant and is not affected by increases in the background noise in the vehicle.
