This Equalizer is a 7-band stereo equalier/crossover specifically created
for the mobile environment. This Equalizer provides powerful features in a
compact size:
• Seven equalization bands (50Hz, 125Hz,320Hz, 750Hz, 2.2KHz, 6kHz, and 16 kHz),
each frequency adjustable from -12 to +12dB (-15 to +15dBfor subwooferfre-
quencies)
• Subwoofer output uses a built-in 18dB per octave electronic crossover fixed at
60Hz or 120Hz.
• Three stereo RCA outputs to drive front, rear, and subwoofer audio amplifiers
• An auxiliary stereo RCA input for use with portable devices, such as an MP3
player or DVD player
• Separate controls for master volume, subwoofer volume (sub level), front/rear
fader, and selection of main
or auxiliary inputs
• Extended frequency response from 20 Hz to 30 kHz with exceptional 100dB
signal-to-noise performance
• Dual light selectable ( orange red and blue)
• Gold-plated RCAconnectors to ensure the best audio signal output
• ISO mounting holes and removable trim ring for custom installation

• Do not operate this product in ways otherthan those described in this manual.
• Do not disassemble
or modifythis unit.
• Do not pour liquid
or poke foreign objects into the unit. Water and humidity may
damage internal circuitry.

4. OPERATIONS
Setting system volume
1. Turn the mastervolume and subwoofer level controls to their minimum settings.
2. Turn the source unit on and increase the volume until you heardistortion.
3. Reduce the volume tojust below the distortion point (approximately 80% of full
volume).
This is the maximum usable musical signal for the source unit. Turning the volume
beyond this point increases noise and distortion without increasing the musical
signal.
Note
Once you set the source unit volume, do not change it, Always use the
volume
control on the Equalizer as the master(main) volume control,
The
Equalizer has better electronics, a higher sound to noise
ratio,
and is more linear than the volume settings on any source
unit available.
Adjusting the controls
This Equalizer provides a graphic adjustment band for each of seven frequency ranges:
sub, low, mid, mid-high and high frequency. You can adjustthe center of each frequency
band to fine tune the acoustical response to yourvehicle's interior.
1. Set all frequencies to the center position. The small dot on the control knob should
be set at 12 o'clock.
2. Play your favorite musictrackand adjust the individual controls to suit your taste.
Avoid extreme settings, which can distort musical peaks.
3. Increase
or decrease the equalizer gain controls to suityourtaste.
4. If your system includes a subwoofer, slowly increase the subwoofer level until you
heara solid bass.
5. If your system includes rear speakers, adjust the fader control to add rear sound.
Set it so most of the musiccomes from the front and only fills the rear.

Setting the low-pass frequency
Set the low pass frequency switch on the top of the Equalizerto either60Hz or
90 Hz depending on the subwooferand subwooferamplifier requirements.
Connecting an MP3 player or video unit
1. Plug the MP3 player or video unit into the auxiliary RCA input on the back of the
Equalizer unit.
2. Make sure the auxiliary button on the front of the unit is out, ready to receive input
from the main
RCA input (not the auxiliary RCA input).
3. Turn the mastervolume to a normal listening level.
4. Press the play button on the auxiliary source.
5. Push in the AUX button to change to the auxiliary source.
6. Using asmall flathead screwdriver, adjust the AUX gain controls located on the top
of the unit
so that the volume of the auxiliary source matches the volume of the
main source.

WARNING!
Toprevent short circuitsduringinstallation, alwaysdiscon-
nect the vehicle'snegative(-) batteryleadbeforemaking any
connections.
• This unit is exclusively for vehicles with a negative ground, 12V battery system.
• A good chassis ground connection
is critical to minimize resistance and avoid noise
problems.
Use the shortest wire possible and securely connect it to the car chassis
and the source unit ground.
•
When routing RCA cables, keep the cables away from the power cables and output
speakerwires.

Crossover. A devicethat limits the range of frequencies sent to a speaker or amplifier.
Equalization: the process of boosting or cutting sound signal frequencies to improve
the qualityof the sound. The term comes from the filters used to add back high
frequencies atthe receiving end of analog transmissions over wires.
Equalization band: the frequency range impacted by a specific filter.
dB: decibel, a measurement of the relative difference in power or intensitybetween
two acoustic signals
Gain control: gain is the amount of amplification (voltage, current or power) of an
audio signal expressed
in dB
Graphic equalizer. a multi-band variable equalizerthat uses mechanical controls to
adjust amplitude.
Hz: Abbreviation for Hertz, a unit of frequency equal to one cycle per second.
