INSTALLATION AND CONNECTIONS

After unpacking the unit, and placing it on a solid
surface capable of supporting its weight, you will
need to make the connections to your audio and
video equipment.

Audio Equipment Connections

We recommend that you use high-quality inter-
connect cables when making connections to
source equipment and recorders to preserve the
integrity of the signals.

When making connections to audio source
equipment or speakers it is always a good prac-
tice to unplug the unit from the AC wall outlet.
This prevents any possibility of accidentally send-
ing audio or transient signals to the speakers
that may damage them.

1. Connect the analog output of a CD player to
the

inputs

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 the signal is distorted.

2. Connect the analog Play/Out jacks of a cas-
sette 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 7500.

3. Connect the digital output of any digital
sources 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 Inputs

*Ó

4. Connect the

Coaxial or Optical Digital

Outputs

on the rear panel of the AVR to the

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

5. Assemble the AM Loop Antenna supplied with
the unit as shown below. 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 system. Note that if the antenna or connec-
tion uses 300-ohm twin-lead cable, you should
use a 300-ohm-to-75-ohm adapter to make the
connection.

7. Connect the front, center and surround speak-
er outputs

to the respective speakers.

To assure that all the audio signals are carried to
your speakers without loss of clarity or resolu-
tion, we suggest that you use high-quality speak-
er cable. Many brands of cable are available and
the choice of cable may be influenced by the dis-
tance between your speakers and the receiver,
the type of speakers you use, personal prefer-
ences 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 rec-
ommend that you use a cable constructed of fine,
multistrand copper with an area greater than 2
mm

Cable with an area of 1.5 mm

may be used for

short runs of less than 4 m. We do not recom-
mend that you use cables with an area less than
1mm

due to the power loss and degradation in

performance that will occur.

Cables that are run inside walls should have the
appropriate markings to indicate listing with any
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 applicable local building
codes in your area.

When connecting wires to the speakers, be cer-
tain 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 will still use a
red terminal for the postive (+) 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 manufacturers may vary from this configu-
ration. To assure proper phase and optimal per-
formance, 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 sur-
round-left and surround-right speakers, even if
the speakers are a different distance from the
AVR 7500.

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 connect-
ed 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
information.

9. If an external multi-channel audio source with
5.1 outputs such as an external digital proces-
sor/decoder, DVD-Audio or SACD player is used,
connect the outputs of that device to the

Channel Direct Inputs

10. If an external multi-channel audio source
with 7.1 outputs such as an external digital
processor/decoder, DVD-Audio or SACD player is
used, first connect the outputs of that device to
the 6 Channel Direct Inputs as noted above, and
then connect the Surround Back Left and
Surround Back Right output channels of the
source device to the

8-Channel Direct Inputs

11. If a 7.1 channel source device is connected
as noted in the item above, you must use an
optional audio power stereo amplifier for the
Surround Back channels. Connect the

SBL

and

SBR Preamp Outputs

to the inputs of the

amplifier feeding those channels' speakers.

Video Equipment Connections

Video equipment is connected in the same manner
as audio components. Again, the use of high-qual-
ity interconnect cables is recommended to pre-
serve signal quality. To ensure best video perform-
ance S-Video sources should be connected to the
AVR 7500 only with their S-Video In/
Outputs, not with their composite video connec-
tors too.

1. Connect a VCR’s audio and video Play/Out
jacks to the

Video 1

Video 2 In

jacks

'#&

on the rear panel. The Audio and

Video Record/In jacks on the VCR should be con-
nected to the

Video 1

Video 2 Out

jacks
