INTRODUCTION

Thank You for Choosing Harman Kardon

®

With the purchase of a Harman Kardon AVR 635, you
are about to begin many years of listening enjoyment.

The AVR 635 has a wide range of features and
options that accommodate virtually any combination
of speakers, room size and program sources. It is
as easy to operate as it is to set up

, but in order to
take maximum advantage of the many advanced
technologies within your new AVR, it is strongly
recommended that you take a few minutes to read
this owner’s manual.

If you have any questions about this product, its instal­lation or its operation, we recommend that you contact
your dealer or installer, as they are your best source
of local information. You may also access a wealth of
information and assistance by visiting our Web site
at www.harmankardon.com.

Description and Features

The AVR 635 is designed to serve as the hub of your
home entertainment system, combining the flexibility
to access the wide range of audio and video source
options available today with the power to handle virtu­ally any type of program material or surround mode.
Thanks to a state-of-the-art DA610 digital signal
processor from Texas Instruments, the AVR 635 offers
precision decoding of all currently available technolo­gies from Dolby Laboratories and DTS

®

. In addition,
older analog and two-channel program sources benefit
from the latest version of Harman International’s

®

processing which creates a wider, more

Logic 7
enveloping sound field with more defined channel
positioning and the ability to create 7.1 sound fields
from 5.1 sources.Additional processing and decoding
options include MP3 (when connected to a compatible
computer) and HDCD

®

for enhanced CD playback as
well as Dolby* Virtual speaker and Dolby Headphone
processing

An important addition to the
of features is EzSet/EQ

.

which automates the configu

,
ration process to make it quicker, easier and more
precise. Using the special microphone supplied with
the unit, EzSet/EQ takes the guesswork out of entering

“size” and crossover information, delay times

speaker
for all channels and output levels. In addition to the
configuration settings, EzSet/EQ also includes room
equalization so that the signals sent to each speaker
are tailored to provide accurate sonic quality with your

room size and

specific combination of speaker type

,

other factors that influence room acoustics.With

EzSet/EQ, your system is custom-configured in a few
minutes with accuracy that previously required expen­sive and hard-to-use test equipment.

In tandem with EzSet/EQ, the AVR 635 includes
a full set of manual configuration settings for those
who wish to custom-trim their system even further.
A Quadruple Crossover bass management system
makes it possible to enter different crossover settings
for each speaker group.

Video connections and system integration is a snap
with the AVR 635, thanks to format cross-conversion
which allows any video input to be output as a high­quality component signal,

complete with the
on-screen menus. For those sources already in com­ponent form, three assignable, wide-bandwidth inputs
are available

, and the Video inputs are renameable.
To further enhance the viewing experience with digital
sources or displays, the AVR 635’s A/V Sync Delay
feature allows you to compensate for the loss of lip
sync due to digital video delays individually for each
input. Full-carrier IR outputs, a bi-directional RS-232
port and a learning remote with a two-line display
are among the many other features that make the
AVR 635’s power simple to use.

The AVR 635’s multizone options and a standard
Zone II remote control make it possible to listen to
a separate source in a room while the main home
theater uses a different source.With assignable rear
surround channel amplifiers, you may create a basic
remote listening zone without any additional equip­ment. For one-wire multiroom connectivity, the
AVR 635 is A-BUS Ready,

®

requiring only a single
Category 5/5e cable and an optional remote module
to power remote speakers while controlling volume
and enabling full control over the program source and
compatible IR-controlled devices.The unit’s Multiroom
outputs may also be used to feed an optional, external
power amplifier and volume control.

The AVR 635’s seven-channel amplifier is our time-

-

honored high-current, ultrawide-bandwidth design with
the power to reproduce the loudest crescendos or
cinema sound effects while remaining virtually free
from distortion or system noise.

Combining state-of-the-art circuitry, digital technology
and proven performance with an elegant design that is
compatible with the latest source components and
video displays, the AVR 635 represents the culmina­tion of Harman Kardon’s fifty-year history of delivering
the finest sonic performance.

‚ Surround Back/Multiroom Speaker Outputs:

These speaker terminals are normally used to power
the surround back left/surround back right speakers
in a 7.1-channel system. However, they may also be
used to power the speakers in a second zone, which
will receive the output selected for a multiroom system.
To change the output fed to these terminals from
the default of the Surround Back speakers to the
Multiroom Output, you must change a setting in the
Advanced Menu of the OSD system. See page 41 for
more information on configuring this speaker output. In

mal surround system use, the brown and black ter-

nor
minals are the surround back left channel positive (+)
and negative (–) connections and the tan and black
terminals are the surround back right positive (+) and
negative (–) terminals. For multiroom use, connect the
brown and black SBL terminals to the red and black
connections on the left remote zone speaker and con­nect the tan and black SBR terminals to the red and
black terminals on the right remote zone speaker.

System Installation

After unpacking the unit, locating it in a place with ade­quate ventilation and placing it on a solid surface capable
of supporting its weight,
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: 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 . Connect the analog Record/In
jacks on the recorder to the
on the AVR 635.

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
Coaxial Digital Audio Inputs KM.

4. Connect the coaxial or optical

ik on the rear panel of the AVR 635 to the 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
and GND Screw Terminals ¡ .

6. Connect the supplied FM antenna to the

§¶ª‚ to the respec-

tive speakers.

o ensure that all the audio signals are carried to your

T
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 recom­mend 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 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 building codes in
your area.

When connecting wires to the speakers, be certain
to observe proper polarity. Note that the positive (+)

minal of each speaker connection has a specific color

ter
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

y convention of using black ter

an industr
negative and red ones for positive, some may vary
from this configuration. To ensure proper phase and

, consult the identification plate on

If you do not know the polarity of your speaker, ask
your dealer for advice before proceeding, or consult
the speaker’s manufacturer.

o

The AVR 635 is designed for flexible use with multi­room systems, external control components and
power amplifiers

.

Main Room Remote Control Extension

If the receiver is placed behind a solid or smoked
glass cabinet door

, the obstruction may prevent the

remote sensor from receiving commands. In this
event, an optional remote sensor may be used.
Connect the output of the remote sensor to the
Remote IR Input Jack g.

If other components are also prevented from receiving
remote commands, only one sensor is needed. Simply
use this unit’
connection from the

s sensor or a remote eye by running a

Remote IR Output Jack h to

the Remote IR Input jack on Harman Kardon or other
compatible equipment.

Multiroom IR Link

The remote room IR receiver should be connected to
the AVR 635 via standard coaxial cable. Plug the IR con­nection cable into the

Multiroom IR Input Jack f on

the AVR 635’s rear panel.

If other Harman Kardon-compatible source equipment
is part of the main room installation, the

Remote IR

Output Jack h on the rear panel should be con-

nected

to the IR IN jack on source equipment. This will

enable the remote room location to control source
equipment functions.

When a remote IR sensor is used to control non­Harman Kardon source equipment, we recommend
that you make a direct connection or use an optional,
external IR “blaster” connected to the

Carrier Output Jack

i. If you are in doubt as to

Remote IR

which IR Output jack to use for the equipment in your
system, contact your dealer or installer, or the manu­facturer’s support site and ask whether the unit to be
controlled uses “full carrier” or “stripped” carrier IR
commands.When “full carrier commands” are used,
make the connection to the

Output Jack

NOTE: All remotely controlled components must be
linked together in a

“daisy chain.” Connect the

jack of one unit to the IR IN of the next to establish
this chain.

Multiroom Connections

The AVR 635 is equipped with multizone capabilities
that allow it to send a separate audio source to the
remote zone from the one selected for use in the
main room.

Depending on your system’s requirement, three
options are available for audio connection:

Option 2: Connect the Multiroom Audio Outputs

power amplifier. Run high-quality speaker wire from
the amplifier to the speakers in the remote room.

Option 3: Taking advantage of the AVR 635’s built-in
seven-channel amplifier, it is possible to use two of the
amplifier channels to power speakers in the remote
room. When using this option, you will not be able to
use the full 7.1-channel capabilities of the AVR 635 in
the main listening room, but you will be able to add
another listening room without external power ampli-

‚. Before using the remote room, you
will need to configure the amplifiers for surround oper
ation by changing a setting in the

MULTIROOM

menu, following the instructions shown on page 41.

NOTE: For all options, you may connect an optional
IR sensor in the remote room to the AVR 635 via an
appropriate cable. Connect the sensor’s cable to the
Multiroom IR Input f on the AVR 635 and use the
Zone II remote to control the room volume. Alter­natively, you may install an optional volume control
between the output of the amplifiers and the speakers.

A-BUS®Installation Connections

The AVR 635 is among the few receivers available
that offer built-in A-BUS Ready operation. When used
with an optional A-BUS product, you have all the ben­efits of remote zone operation without the need for an
external power amplifier.

To use the AVR 635 with an approved A-BUS prod-

simply connect it to the AVR 635 using standard

uct,

y 5 wiring that is properly rated for the specific

Categor
in-wall installation. Terminate the wiring at the receiver
end to a standard RJ-45 connector in compliance
with the instructions furnished with the A-BUS product.

No further installation or adjustment is needed, as the
A-BUS jack on the AVR 635 routes the signals to their
proper destination for power, signal source and control.
The output fed to the A-BUS jack is determined by the
AVR 635’s multiroom system and menus.

or technician familiar with the equipment being used.

The RS-232 port may also be used as an access
point through which the AVR 635’s operating system
and surround mode memories may be updated via
connection to a compatible computer. At the time
that any upgrade is available, instructions for making
the connection and installing the upgrade will be
available through the Product Support area of the
Harman Kardon Web site at harmankardon.com.

The physical connection to the AVR 635’s RS-232
port is a standard D-SUB 9 connection,
compatible and proper operation,
commands and pin wiring schemes may be required.

AC Power Connections
