Setup
Common System Setup
The input MODE switch will “sum” or
combine the right and left channel signals
in the MONO position to improve bass
performance. Select MONO only when the
amp is being used for subwoofers.
The XOVER Mode switch sets the type
of crossover that will be active. 4 channel
models will have two switches, one for each
set of channels.
The HPF (high pass filter) control will limit the
output below the selected frequency. This is
typically used to protect midrange and high
frequency speakers from damage and to
allow a smooth transition from a subwoofer.
The LPF (low pass filter) control will limit
output above the selected frequency. This
is used to allow a smooth transition to the
higher frequency speakers.
1.
If possible, with the source unit off, confirm that the primary volume control is
turned down (counter clockwise).
2.
Turn on the source unit (CD, or MP3 player). Re-confirm that the volume is
turned down. Make sure the source unit controls; balance, fader, bass and
treble are all set to center or “0” adjustment. Make sure that the green LED on
the end of the amplifier is illuminated.
3.
Play a clean musical selection of which you are very familiar. CD is preferred.
Do not use radio signals for level setting. Hit play and start turning the volume
of the source unit up.
4.
Stop increasing the source unit volume when you reach 3/4 (about 75%) or until
you hear speakers begin to slightly start producing distortion.
5.
Increase the amplifier level (clockwise) until distortion is heard, then back
the level down (counter clockwise) until the distortion is eliminated. Small
adjustments may need to be made to balance the levels of multiple amplifiers.
The BASS BOOST or BASS EQ control
will increase the output at 45Hz for more
pronounced bass. Exercise caution.
Increase the level in small amounts until
distortion is noticed, then back off a little.
Some models include a bass
remote. Avoid adjusting the bass
remote while operating vehicle.

This is a critical step to insure your amplifier
is properly adjusted to match the signal
output level of your source unit.
