SET THE BASS BOOST

GX-A604: When you're using the amplifier's rear channels to power a subwoofer, the Bass Boost switch can provide 12dB of bass boost at 45Hz.
(The switch only affects the amplifier's rear channels.) Set this switch according to your personal taste, but if using it causes audible distortion or
bottoming of your subwoofer we recommend setting it to "OFF." CAUTION: Only use the Bass Boost switch if you've configured the rear channels
to power a subwoofer. Using the Bass Boost switch with full-range speakers can damage the speakers.

to "OFF." CAUTION: Only use the Bass Boost switch if you're using the amplifier to power a subwoofer. Using the Bass Boost switch with full-range
speakers can damage the speakers.
GX-A3001: 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
