Owner’s Enjoyment Manual
4. Volume:
Because the FOUR.1
i
is a pre-amp unit, it
serves as the main control unit in the audio system. It has a
master volume control that controls the output to all of the
amplifiers. Turn the volume control of your source unit all
the way up and deliver maximum voltage to the FOUR.1
i
.
Better signal-to-noise ratio and maximum SPL !
5. Fader:
The fader control will allow you to fade the
signal level back and forth between front and rear amplifier
channels. This means you can have front and rear fading
even though your source unit only has two-channel outputs.

i
1. Graphic Equalization Bands:
Four stereo con-
trols centered at 125Hz, 500Hz, 2KHz, and 8KHz with 12dB of
cut or boost. These controls should be used to tweak your
system, depending upon your mood.
2. Para-BASS Controls:
Two simple controls allow for
killer bass tweaking. The sweep knob selects the center
frequency, between 40 and 80Hz. The gain knob provides
12dB of boost or cut, centered at the sweep frequency.
3. Auxiliary Inputs:
The FOUR.1
i
has an auxiliary
input to hook up a second source unit, like an outboard
video system or even a factory radio. The input is activated
by the left most switch located on the front faceplate.
