FEATURES
Graphic Stereo Equalization: Four independent frequency controls turn your dashboard into a mini-mixing
board. Each one controls a specific range or “band” allowing the user to boost or cut frequencies and fine
tune the systems performance.
Bi-polar Power Supply: Regulated high speed DC power supply reduces switching loss and results in a
cleaner sine wave signal.
Master Volume Control: This one knob allows the user to raise the volume on your source units to their
maximum level, eliminating the need to adjust multiple controls.
Sub Volume Control: If you are using a dedicated amplifier for your subwoofer, this control will allow the user
to independently adjust the output level of the woofer.
Sub Frequency Selector: Switchable to either 80Hz or 120Hz as the center frequency for the subwoofer.
Auxiliary Input Selector: The SOURCE switch on the front of the equalizer allows the user to switch back and
forth between two sources: the Radio Input or the AUX Input on the rear panel.
Front Panel Aux Input: The front panel AUX Input is a convenient and easy way to hook-up a portable MP3
player or IPod®* to your system.
Fader Control: Allows easy balancing between the front and rear speakers when used with separate amplifiers for the front and rear channels.
Night Illumination: When the EQ is powered-on the control knobs are back lit with red illumination for easier
adjustment at night.

CONTROL PANEL LAYOUT
1. SUB VOL Control
The Subwoofer Volume control independently adjusts the output level of the woofer to a level you enjoy
(requires use of a dedicated woofer or bass amplifier connected to the rear RCA style inputs).
2. SUB FREQ Button
This switch selects the Subwoofer Center Frequency to either 80Hz or 120Hz and is used in conjunction with
the SUB VOL control.
3. EQUALIZER CONTROLS
These four rotary knobs control the frequency response by “boosting” or “cutting” the BASS, MID-BASS, MID,
and HIGH signals by 18dB. Centered at 70Hz, 250Hz, 3kHz, 15kHz respectively, these controls can be used
to fine tune your system to suit your taste and listening environment.
4. FADER CONTROL
This control adjusts the volume between the front and rear amplifier channels as desired. Front and rear
fading is now possible even with source units that have only two-channel outputs.
5. SOURCE Button
This faceplate switch selects the equalizer input source: RADIO (Head unit) input or the AUX, both on the rear
of the chassis.
6. VOLUME CONTROL
This control adjusts the output level of the system.
7. AUX FRONT INPUT 3.5mm Jack
This front panel input makes it easy to add MP3 or iPod®* as a music source. When a device is plugged in
to this input, it overrides both rear inputs.
