Dual Zone Concept

The concept behind E.DZ is the ability to equalize the front stage and rear fill of the vehicle
audio system independently. The front stage is the focal point of your audio system, requiring
different processing than the rear fill. The front stage should appear higher on the dash, very
crisp and clear, and a slightly higher amplitude level when compared to the rear fill. The rear
fill does not require as extensive processing like the front stage, as it is not the focal point of
the audio system. E.DZ achieves this with independent multi-band equalization of the front
stage and rear fill audio signals.

Cautions

High-powered car audio systems may produce sound pressure lev els that exceed the
threshold at which hearing loss may result. They may also impair a driver's ability to hear
traffic sounds or emergency vehicles. Use common sense and practice safe listening habits
when listening to or adjusting your audio system.

Control Panel Functions

1.Input Selection Switch

The Input Selection Switch controls which of the two inputs the E.DZ processes. Press the switch
in to accept the audio signal from your source unit through the CD input. Leave the switch out to
accept and process the audio signal from a secondary source unit or auxiliary device through the
AUX inputs.

The Mater Volume Control can be used as a primary or secondary volume control for your audio
system. Generally, the source unit volume is set at a mod erate l evel, then utilize the E.DZ's
Master Volu me Co ntrol. The ring around the Mater Volum e Con trol is a fader, to inc rease or
decrease the output levels between the front and rear outputs.

3.Subwoofer Level Control

The Subwoofer Level Control will increase or decrease the output level of the subwoofer pre-amp
output in relation to the Master Volume Control.

4.Graphic Equalizer Controls

The Graphic Equalizer Controls will increase or decrease the level of its corresponding frequency,

-18dB or +18dB. Turn the knob counter-clockwise (left) to decrease the level, clockwise (right) to
increase the level.
