Installation, Set Up & Configuration
System Installation
After unpacking the unit, and placing it
in on a solid surface capable of support-
ing its weight, you will need to make the
connections to your audio and video
equipment. These steps need to be done
only when the unit is first installed, or
when a change is made to the input
source equipment.
Audio Input and Output Connections
Use the “Audio and Systems
Connections” Diagram in the inside
front cover as a guide to connecting
audio components and speakers to the
rear panel. We recommend that you use
high quality cables when making con-
nections to source equipment and
recorders to preserve the quality of the
signals.
NOTE: When making connections to
audio source equipment or speakers it is
always a good practice to unplug the unit
from the AC wall plug. This prevents any
possibility of accidentally sending audio
or transient signals to the speakers that
may damage them.
1. For playback only sources, such as a
tuner, CD player, CD changer, external
phono preamp or external digital to ana-
log converter, connect the output jacks of
the player to the appropriately labeled
inputs on the rear panel. O®

NOTE: When the source device has both
fixed and variable audio outputs it is best
to use the fixed output unless you find
that the input to the receiver is so low
that the sound is noisy, or high that the
signal is distorted.
2. When connecting recording devices
such as cassette recorders, open reel tape
decks, DCC, DAT or MD, connect the
PLAY/OUT jacks of the recorder to the IN
jacks @@. Connect the RECORD/IN
jacks on the recorder to the OUT jacks
OG.
3. Connect the front, center and sur-
round speaker outputs @@OO©@ to
the respective speakers.
To assure that all the audio signals are
carried to your speakers without loss of
clarity or resolution, we suggest the use
of high quality speaker cable. Many
brands are available, and the choice may
be influenced by the distance between
your speakers and this amplifier, the type
of speakers you use, personal preferences
and other factors. Your dealer or installer
is a valuable resource to consult in
selecting the proper cable.
Regardless of the brand of cable selected,
we recommend that you use a cable con-
structed of fine, multi-strand copper with
a gauge of 14 or larger. Remember, that
in specifying cable, the lower the num-
ber, the thicker the cable.
Cable with a gauge of 16 may be used for
short runs of less than ten feet. We do not
recommend that you use cables with an
AWG equivalent of 18 or higher due to
the power loss and degradation in perfor-
mance that will occur.
One way to insure that cables will deliver
a predictable level of performance is to
use Home THX® certified cables. This cer-
tification assures that the cables have
met a rigorous set of specifications
designed for home theater applications.
Cables that are run inside walls should
have the appropriate markings to indi-
cate listing with the appropriate testing
agency standards. Questions about run-
ning cables inside walls should be
referred to your installer or electrical
contractor.
When connecting wires to the speakers,
be certain to observe proper polarity.
Remember to connect the “negative” or
“black” wire to the same terminal on the
receiver and the speaker. Similarly, the
“positive” or “Red” wire should be con-
nected to the like terminal on the AVI250
and speaker.
