System Installation
After unpacking the unit, locating it in a
place with adequate ventilation and plac-
ing it on a solid surface capable of support-
ing its weight, you will need to make the
connections 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 outlet before making any audio or video
system connections.
Audio Equipment Connections
We recommend that you use high-quality
interconnect cables when making connec-
tions to source equipment and recorders
to preserve the integrity of the signals.
1. Connect the analog output of a CD
player to the CD Audio Inputs j.
NOTE: When the 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 Input Jacks .
Connect the analog Record/In jacks on
the recorder to the Tape Output
Jacks on the AVR580.
3. Connect the output of any digital
sources such as a CD or DVD changer
or player, advanced video game, a dig-
ital 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 gi on the rear panel
of the AVR580 to the matching digital
input connections on a CD-R or MiniDisc
recorder.
5. Assemble the AM Loop Antenna sup-
plied 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 ¡.
6. Connect the supplied FM antenna to
the FM (75-ohm) Connection ™. 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 con-
nection uses 300-ohm twin-lead cable,
you must use the 300-ohm-to-75-ohm
adapter supplied with the unit to make
the connection.
7. Connect the Front, Center, Surround
and Surround Back Speaker
Outputs ∞§•ª to the respective
speakers.
To ensure that all the audio signals are
carried to your speakers without loss of
clarity or resolution, we suggest 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 recommend that you use a cable con-
structed of
multistrand copper 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 3 meters (10 feet).
We do not recommend that you use
cables with an AWG equivalent of 18 or
higher, due to the power loss and degra-
dation in performance that will occur.
Cables that are run inside walls should
have the appropriate 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 local 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 manufactur-
ers 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 pro-
ceeding, or consult the speaker’s manu-
facturer.
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 surround-right speakers, even if the
speakers are a different distance from
the AVR580.
8. Connections to a subwoofer are nor-
mally made via a line-level audio con-
nection from the Subwoofer Output
¢to the line-level input of a sub-
woofer with a built-in amplifier. When
a passive subwoofer is used, the con-
nection first goes to a power amplifier,
which will be connected to one or
more subwoofer speakers. If you are
using a powered subwoofer that does
not have line-level input connections,
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 .
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 a VCR’s or other video source’s
audio and video Play/Out jacks to the
Video 1 Audio and Video Input
Jacks ›on the rear panel. The
Audio and Video Record/In jacks on
the VCR should be connected to the
Video 1 Audio and Video Output
Jacks fion the AVR580.
