Bass BOOst
When you’re using the amplifier’s rear channels to power a subwoofer, the Bass Boost control can provide up to 12dB
of bass boost at 45Hz. Set this control according to your personal taste, but be careful not to set the control at a high
enough level to cause audible distortion or bottoming of your subwoofer.
cautiOn:
Only use the Bass Boost control
if you’ve configured the rear channels to power a subwoofer. Using the Bass Boost control with full-range speakers
can damage the speakers.
