INSTALLATION AND CONNECTIONS

System Installation

After unpacking the unit, locating it in a place with ade-
quate ventilation and placing it on a solid surface capable
of supporting its weight, you will need to make the con-
nections to your audio and video equipment.
IMPORTANT NOTE: For your personal safety and to
avoid possible damage to your equipment and speakers,
it is always a good practice to turn off and unplug the
AVR and ALL source equipment from the AC output
before making any audio or video system connections.
Audio Equipment Connections
We recommend that you use high-quality interconnect
cables when making connections to source equipment
and recorders to preserve the integrity of the signals.
1. Connect the analog output of a CD player to the
CD Inputs ƒ.
NOTE: If your CD player 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 so high that it is distorted.
2. Connect the analog Play/Out jacks of a cassette
deck, MD, CD-R or other audio recorder to the
Tape Inputs É. Connect the analog Record/In
jacks on the recorder to the Tape Outputs ∂
on the AVR 7300.
3. Connect the output of any digital audio source
such as a CD or DVD changer or player, advanced
video game, a digital satellite receiver, HDTV tuner
or digital cable set-top box or the output of a
compatible computer sound card to the Optical
and Coaxial Digital Audio Inputs ®†
.

4. Connect the coaxial or optical Digital Audio Outputs
ϧ
of the AVR 7300 to the
11 13
matching digital input connections on a CD-R or
MiniDisc recorder.
5. Assemble the AM loop antenna supplied with the unit
so that the tabs at the bottom of the antenna loop
snap into the holes in the base. Connect it to the
AM and GND Screw Terminals X.
6. Connect the supplied FM antenna to the FM
(75-Ohm) Connection W. The FM antenna may
be an external roof antenna, an inside powered
or wire-lead antenna or a connection from a cable
TV system. If the antenna or connection uses

300-ohm twin-lead cable, you must use an optional
300-ohm-to-75-ohm adapter to make the
connection.
7. Connect the front, center, surround and surround
back speaker outputs å∫ç√ to the respec-
tive speakers.
To ensure that all the audio signals are carried to your
speakers without loss of clarity or resolution, we sug-
gest that you use high-quality speaker cable. Many
brands of cable are available and the choice of cable
may be influenced by the distance between your
speakers and the receiver, 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 recom-
mend that you use cable with a gauge of 14 or smaller.
Remember that in specifying cable, the lower the
number, the thicker the cable.
Cable with a gauge of 16 may be used for short runs
of less than 10 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 performance
that will occur.
Cables that are run inside walls should have the appro-
priate markings to indicate listing with UL, CSA or other
appropriate testing agency standards. Questions about
running cables inside walls should be referred to your
installer or a licensed electrician who is familiar with
the NEC and/or the applicable building codes in
your area.

When connecting wires to the speakers, be certain
to observe proper polarity. Note that the positive (+)
terminal of each speaker connection now carries a
specific color code, as noted on page 9. However,
most speakers still use a red terminal for the positive
connection. Connect the "negative" or "black" wire
to the same terminal on both the receiver and the
speaker.
NOTE: While most speaker manufacturers adhere to
an industry convention of using black terminals for
negative and red ones for positive, some may vary
from this configuration. To ensure proper phase and
optimal performance, consult the identification plate on
your speaker or the speaker's manual to verify polarity.
If you do not know the polarity of your speaker, ask
your dealer for advice before proceeding, or consult
the speaker's manufacturer.
We also recommend that the length of cable used
to connect speaker pairs be identical. For example,
use the same length piece of cable to connect the
front-left and front-right or surround-left and sur-
round-right speakers, even if the speakers are a
different distance from the AVR 7300.
8. Connections to a subwoofer are normally made via
a line-level audio connection from the Subwoofer
Output µ to the line-level input of a subwoofer
with a built-in amplifier. When a passive subwoofer
is used, the connection first goes to a power ampli-
fier, which will be connected to one or more sub-
woofer speakers. If you are using a powered sub-
woofer that does not have line-level input connec-
tions, follow the instructions furnished with the
speaker for connection information.
9. If an external multichannel audio source with 5.1
outputs such as an external digital processor/
decoder, DVD-Audio or SACD player is used,
connect the outputs of that device to the
8-Channel Direct Inputs Ü.
Video Equipment Connections
Video equipment is connected in the same manner
as audio components. Again, the use of high-quality
interconnect cables is recommended to preserve
signal quality.
1. Connect the analog left/right audio and composite
video or S-Video Play/Out jack of a VCR, personal
video receiver (PVR) or DVD-recorder to the
Video 1 or Video 2 Audio and Video Input
Jacks ñ˚NT on the rear panel. We recom-
mend that VCRs and PVRs be connected to the
Video 1 Input jacks as the remote control is pro-
grammed for a VCR or PVR.
2. Connect the analog left/right audio and composite
video or S-Video Record/In jacks of a VCR, person-
al video recorder (PVR) or DVD-recorder to the
Video 1 or Video 2 Audio and Video Output
Jacks ∆πMU on the rear panel, matching
the device connected to the Video 1 or Video 2
Audio and Video Inputs.
3. Connect the analog left/right audio and composite
video or S-Video Play/Out jacks of any video play-
back device to the Video 3 or Video 4 Audio and
Video Input Jacks ˙îKV on the rear
panel. Although any type of video source device
may be connected to these jacks, the remote con-
trol has the commands for the Video 3 inputs set to
control a cable set-top box and the commands for
the Video 4 inputs set to control a satellite receiver.
NOTE: The device connection recommendations
shown in steps 1, 2 and 3 enable you to take advan-
tage of the device types preprogrammed for each
input on the remote control. However, if you choose to
connect a different type of device you may reassign
the remote codes so that they match the device by
using the instruction for "Changing Devices," as shown
