This model is intended for those who value the acoustic benefits of a
multi - band Graphic Equalizer but who also desire higher audio power level
capabilities than can be obtain in an in-dash unit. Being a passive Equalizer, it
contain power amplifiers to drive speakers directly, Also provides one stereo
signal line output and 1 pair sub-woofer output can be connected to remote high-
power amplifiers. The ten center-frequencies are connected in the critical
50Hz to 12Hz region where compensation is most needed.
LOCATION AND FUNCTION OF CONTROL
1. FADER KNOB
Allow front to rear balancing in four speaker systems for best
directional imaging.
2. EQ SLIDE CONTROLS
Each slide controls the amount of boost or cut in one small part of the total
audio frequency range. With all slides in the center position, the overall
frequency response is flat. By moving any slide up or down. The output
within the band is increased or decreased by up to 12db.
3. LED INDICATOR
4. CD INPUT JACK
5. POWER BUTTON
Press it to turn on or off the unit.

PRECAUTIONS
1. Most speaker systems require rather heavy boost at the lowest
frequencies due to the large amount of air that must be moved. Speaker
woofer cones responder between 45-60Hz where output is higher so do
not boost much at 60Hz. Use heavy boost at 100Hz, less boost at
400Hz.
2. Due to sound-wave reflections between the front and rear windshields of
a typical vehicle, there may be heavy loss between 700Hz to 1.3KHz so
moderate boost here is very effective and will create more presence for
vocalists.
3. The mid-range from 3 to 6KHz should not require much change from
flat [center] most speakers work well here. Adjust per your taste.
4. Due to limitations in human hearings. Sound above 8KHz is not heard
very well. Moderate boost at 1KHz adds a crisp character when
percussion instruments are present.
