Configuration/Setup
The gain control is used to obtain the best possible match
between the head unit audio output and the amplifier input.
• Begin by turning the input level control fully
counterclockwise.
• Next, turn up the head unit volume control around 3/4
of the way up.
• Adjust the input level control clockwise until audible
distortion is heard, then slightly counterclockwise to
provide the best match.
• Repeat for all input level controls.
The low pass filter is always enabled, allowing only bass
frequencies to output from the subwoofer. Turn the X-OVER
FREQ knob to adjust the bass frequency.
The subsonic filter limits very low frequencies from being
sent to the subwoofer. Turn the SUBSONIC FILTER knob
to adjust the frequency of bass that is filtered out. Match
this setting with the low end frequency response of your
subwoofer.

provide its increase. Turn the BASS FREQ knob clockwise
to center the bass boost around higher frequencies or
counterclockwise to center the the bass boost around lower
frequencies.
Increases the volume of bass by a variable amount,
centered at the bass frequency adjustment. Turn the BASS
BOOST knob clockwise to increase the volume of the bass.
Adjust this control with caution, as improper use can
damage speakers.
The LED indicator illuminates green during normal
operation (POWER) and red when the amplifier detects a
fault (PROTECT).
When the remote bass control is connected, turning the
knob will adjust the gain of the amplifier. Connect the
remote bass control connector to the amplifier.
Important: Turn the Gain on the side panel of the amplifier
to MAX to allow the remote bass control to function
properly.
