Input Gain Control: The input gain control is not a
volume control. It matches the output of the source
unit to the input level of the amplifier. Maximum power
out of the amplifier is possible with the gain in the
lowest position. Incorrectly setting the gain can result
in distorted output or damage to, and premature
failure of, your enclosure. For a quick setup, turn the
source unit up to about 3/4 volume (if the source unit
goes to 30, turn it to 25). Slowly turn up (clockwise)
the gain on the amplifier until you can hear audible
distortion, then turn it down a little.
Phase Switch: The phase switch lets you invert the
phase of the signal played through your powered
subwoofer. This is useful if the speakers in your
system are out of phase with the subwoofer. Toggle
this switch to find the position that gives you the best
bass response.
X-Over Freq: The variable crossover on the side
panel allows you to adjust the crossover frequency
from 50–120Hz. The setting for this control is
subjective; 80Hz is a good place to start.
Remote Bass Control: With the included remote
bass control, you have the ability to control the output
level of your powered enclosure remotely. To surface-
mount the remote bass level control, simply screw
the remote to the chosen location, then run the cable
from the controller to the “Remote Bass” jack on the
amplifier panel. Do NOT connect/disconnect while
the amplifier is on.
