Setup
The illustrations below describe the various controls. Refer to
the illustration that matches your amplier.
The level control purpose is to match the output of your source signal to the
amplier. Refer to the section C for detailed instructions.
This switch will set the amplier to have a full frequency output or to lter out high
or low frequencies.
The Bass EQ control will increase the power output at 45Hz for more pronounced
bass. Exercise caution when using this control. Increase the level in small
amounts until distortion is noticed, then back off a little.

1. If possible, with the source unit off, conrm that the primary volume control is
turned down (counter clockwise).
2. Turn on the source unit (CD, or MP3 player). Re-conrm 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 amplier 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 amplier gain (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 ampliers.
This is a critical step to insure your amplier
is properly adjusted to match the signal
output level of your source unit.
THIS IS NOT A VOLUME CONTROL!

NOTE - If the RCA’s are plugged into the amplier and the
TURN ON MODE is in the DC ON position, the amplier
will NOT turn on. Please re-read this document or hire a
professional installer.
REM TURN ON / DC SENSE ON SWITCH
There are two methods of switching the amplier on and off. Select
the appropriate position suited for your application.
REM TURN ON
This will turn on the amplier when a +12v switched power typically
from a source unit, is connected to the Amp Turn on - BLUE wire on
the main power connection harness.

The DC SENSE is for use with the source units that do not offer
RCA outputs.
