Connects to the DVD source with 3.5mm plug cable.  
to select the AUX or DVD inputs.  
2. DVD & AUX input switch  
3. fader control  
• in a 2 Amplifier, 4 Speaker system, rotating the knob  
to the FRONT side increases the level of the front speakers;  
rotating to the REAR side increase level of the rear  
speakers. At mid position, both sets of speakers are at  
maximum level.  
• in a 2 Speaker system, the fader control should be  
rotated to the position which provides highest levels for  
both sets of speakers.  
4. volume control  
allows adjustment of sound level for particular program  
material or source.  
5. subwoofer output volume  
this control adjusts output level of subwoofer RCA jack.  
6. subwoofer frequency control  
lets you adjust the subwoofer crossover frequency point  
from 30-250 Hz.  
7-10. 4 band parametric equalizer controls  
11-12. DVD and AUX inputs  
this four-band equalizer gives you to control over the  
output levels at various frequency.  
RCA cables are used to connect your car stereo head  
unit, DVD player, or other source to either the line or  
AUX inputs.  
13-15. subwoofer/rear/front  
channel outputs  
RCA cables are used to connect the subwoofer channel  
outputs to the subwoofer channel amplifier inputs, the  
rear channel outputs to the rear channel amplifier inputs,  
and the front channel outputs to the front channel  
amplifier inputs.  
16-17. DVD/AUX input gain adjustments  
power connections  
allows you to adjust the left and right channel input  
sensitivity to match the output level from your DVD or  
auxiliary source.  
connect to power source as follows:  
+12V: Connect a red wire of at least 12 gauge to the  
car battery or other power source.  
GROUND: Connect a black wire of at least 12 gauge  
to car chassis for ground connection  
REMOTE: Connect an orange wire to remote activating  
(12V DC) wire of car stereo or other head unit.

When making electrical  
4 mm plain  
washer (2)  
connections to your amplifier,  
please observe the following:  
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 processors GROUND to a good chassis ground, near where the unit is  
mounted, or to the case of the head unit.  
Connect the signal processors 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 EQs, crossovers or amplifiers.)  
Connect stereo RCA cables from the heads 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).  
Adjust each of the crossover or equalizer controls to achieve the desired sound characteristics.
