Owner’s Enjoyment Manual
Master Volume:
The FOUR.1
i
has its own master volume KNOB (no
annoying up & down switches for us) to control the signal
output to the amplifiers. Raise the volume level on your
source units to their maximum and you will never need to
touch them again.
Fader Control:
For easy balancing between the front and rear speakers the
FOUR.1
i
has four output channels and a fader control.
Balanced Inputs & Outputs:
The FOUR.1
i
uses a
unique balanced differential input circuit that helps cancel
any noise that radiates into the signal path between the
source unit and your FOUR.1
i
. The FOUR.1
i
then sends this
balanced signal downstream to another processor or ampli-
fier that has balanced inputs (blatant plug for AudioControl
products) which will keep it noise-free.

The Most Important Feature Of All:
Reliability. That’s right, your AudioControl FOUR.1
i
comes
with a full 5 year parts and labor warranty when it is in-
stalled by an authorized United States AudioControl dealer.
These seasoned pros have the training and the equipment to
take care of the job quickly and not leave your dashboard
looking like swiss cheese. Keep in mind that if you or your
friends who are “good with electronics” choose to install it,
your FOUR.1
i
still has a 1 year parts and labor warranty.
To activate your warranty, you need to FILL OUT AND
SEND IN YOUR WARRANTY CARD! Also, save your invoice
or sales slip as proof of purchase. Not only are these neces-
sary for warranty purposes, they are also important if the
unforeseen disappearance of your FOUR.1
i
should happen
while you are socializing at the local espresso and
salmon bar. Insurance companies have
very little imagination.
