INSTALLATION AND CONNECTIONS

System Installation

After unpacking the unit, locating it in a place with ade-
quate vantilation 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 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 Audio Inputs

NOTE:

When the CD player has both fixed and vari-

able 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 AVR 525.

3. Connect the output of any digital sources such as
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 compati-
ble computer sound card to the

Optical

and

Coaxial Digital Audio Inputs

4. Connect the coaxial or optical

Digital Audio Outputs

on the rear panel of the AVR 525 to the matching

digital input connections on a CD-R or MiniDisc recorder.

5. Assemble the AM Loop Antenna supplied with the
unit. Connect it to the

and

GND Screw

Terminals

6. Connect the supplied FM antenna to the

(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 connection 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 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 deal-
er 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 a cable constructed 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 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 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 local building codes in
your area.

When connecting wires to the speakers, be certain to
observe proper polarity. Note that the positive (+) ter-
minal of each speaker connection now carries a spe-
cific color code as noted on page 8. 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 dif-
ferent distance from the AVR 525.

8. Connections to a subwoofer are normally made via
a line-level audio connection from the

Subwoofer

Output

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 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 instruc-
tions furnished with the speaker for connection infor-
mation.

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 inter-
connect 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/Video 2 Audio

and Video Input Jacks

ﬂ°

on the rear

panel. The Audio and Video Record/In jacks on the
VCR should be connected to the

Video 1/Video 2

Audio and Video Output Jacks

‡·

the AVR 525.

2. Connect the analog audio and video outputs of a
satellite receiver, cable TV converter or television set or
any other video source to the

VIdeo 3 Audio and
