Function
1
EQ Frequency Controls
These switches determine the frequencies the gain
knobs on the front panel will affect. Setting a switch
on one of the 5 bands on top of the equalizer permits
the corresponding control on the front panel to raise
or lower the gain at that frequency.
2
Allows you to adjust the left and right channel
input sensitivity to match the output level from
your line or auxiliary source.
Input Gain Adjustments
This switch selects the aux or line inputs.
3
Aux Input Switch
Turning the controls clockwise increases the level
of the sound at the frequency that you have set on
the EQ’s top panel. Counter-clockwise reduces the
level at that frequency. Choose the settings which
best match your system and your prefered audio
response.

Parametric EQ Controls
5
Turning this control clockwise increases the
subwoofer channel level.
Subwoofer Gain Control
By rotating this selector you can choose any
crossover frequency from 40Hz to 400Hz. Turning
the control clockwise permits more upper bass
to travel through the sub channel.

wiring
signal processors
Connect 12V DC from a constant battery source to a +12V slip-on spade terminal
and install a one (1)amp fuse in line.
Connect the signal processor’s GROUND to a good chassis ground, near where
the unit is mounted, or to the case of the head unit.
Connect the signal processor’s REMOTE TURN-ON lead to the remote turn-
on lead out of the head unit, and install a 1/2 amp fuse in line. (A relay
should be used if turning on more than one component, such as EQ’s,
crossovers or amplifiers.)
Connect stereo RCA cables from the head’s left and right front outputs to
the left and right inputs of the signal processor.
Connect stereo RCA cables from the left and right outputs, (and low, mid
and high outputs if applicable), of the signal processor to the left and right
inputs of your amplifier(s)or additional signal processor(s).
Turn the unit on, and adjust the input gain on the signal processor to match
the output of the head unit (1/2, or at center position, is about 1 V). Be careful
not to overdrive the input of your amplifier(s)or signal processor(s). Us e
clip detectors to adjust output.
Adjust each of the crossover or equalizer controls to achieve the desired
sound characteristics.
