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 outputs 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 140.

3. Connect the 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 Audio Inputs

·d

. We recommend

connecting the coaxial digital audio output of your
DVD player to the

Coax 1 Digital Audio Input

since that digital input is assigned to the DVD source
by default.

4. Connect the

Coaxial

Optical Digital Audio

Outputs

fl‡

on the rear panel of the AVR 140 to the

matching digital input connections on a CD-R or MiniDisc
or other digital 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

Antenna 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. With the AVR 140 turned off, connect the optional
Harman Kardon

Digital Media

Player (DMP) Connector

. Your compatible

Apple

iPod

may be docked in

when you

wish to use it as your audio source device. Video
materials stored on the iPod are not able to be viewed
using the AVR.

8. 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 dealer
or installer is a valuable resource to consult in select-
ing 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 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 local building codes in
your area.

When connecting wires to the speakers, observe
proper polarity. Note that the positive (+) terminal of
each speaker connection may carry a specific color
code, as noted on page 7. However, many speakers
still use a red terminal for the positive (+) connection.
Connect the “negative” or “black” wire to the same ter-
minal 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 140.

Note that it is not possible to use the AVR 140 in a
7.1-channel configuration. Any source information
that the AVR receives or derives for the surround
back left and right channels, e.g. through the

6/8-

Channel Direct Inputs

or during 7-channel

Stereo processing, is combined and outputted
to the single-channel

Surround Back Speaker

Outputs

9. 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 subwoofers. If you
are using a powered subwoofer that does not have
line-level input connections, follow the instructions fur-
nished with the speaker for connection information.

10. If an external multichannel audio source with 5.1,
6.1, 7.1 outputs such as an external digital proces-
sor/decoder, DVD-Audio or SACD player is used, con-
nect the outputs of that device to the

6/8-Channel

Direct Inputs

Video Equipment Connections

Video equipment is connected in the same manner as
audio components. The use of high-quality interconnect
cables is recommended to preserve signal quality.

1. Connect a VCR’s, DVD recorder’s, personal video
recorder’s or other video source’s audio and video
Play/Out jacks to the

Video 1 Audio

Video

and/or

S-Video Input Jacks

on the rear panel. The

Audio and Video Record/In jacks on the recorder
should be connected to the

Video 1 Audio/Video

and/or

S-Video Output Jacks

on the AVR 140.

Although any video device may be connected to these
jacks, we recommend connecting your video recorder
so that you may take advantage of the fact that the
remote control is preprogrammed with video recorder
product codes for the Video 1 device.

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

Video 2 Audio/Video
