System And Power Connections - Harman Kardon AVR 635 Owner's Manual

If your system requires direct connection of a video
source to your display, we suggest that you consider
programming the VDI Buttons w so that you may
change the input used by your display from the AVR's
remote. For information on "learning" remote codes
into a button on the AVR remote, follow the instruc-
tions shown on page 44.

the receiver to the composite or S-video input of

8. If the component video inputs are used, connect
the Component Video Monitor Outputs b to
the component video inputs of your TV, projector
or display device.
9. If you have a camcorder, video game or other
audio/video device that is connected to the AVR on
a temporary rather than permanent basis, connect
the audio, video and digital audio outputs of that
device to the Front-Panel Inputs KMN. A
device connected here is selected as the Video 4
input, and the digital inputs must be assigned to the
Video 4 input. (See page 21 for more information
on input configuration.)

System and Power Connections

The AVR 635 is designed for flexible use with multi-
room 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's sensor or a remote eye by running a
connection from the Remote IR Output Jack h to
45 43
the Remote IR Input jack on Harman Kardon or other
44 42
compatible equipment.

Output Jack h on the rear panel should be con-

nected to the IR IN jack on source equipment. This will
39 45 49
enable the remote room location to control source
44
38 48
43 equipment functions.
42
When a remote IR sensor is used to control non-
Harman Kardon source equipment, we recommend
that you make a direct connection or use an optional,
51
47
external IR "blaster" connected to the Remote IR
46 50
Carrier Output Jack i. If you are in doubt as to
45 49
51
which IR Output jack to use for the equipment in your

system, contact your dealer or installer, or the manu-

facturer's support site and ask whether the unit to be
42
39 45 49
48
44 controlled uses "full carrier" or "stripped" carrier IR
38 48
43
commands. When "full carrier commands" are used,
42
make the connection to the Remote IR Carrier
Output Jack i. Otherwise, make the connection to
the Remote IR Output Jack h as noted above.
NOTE: All remotely controlled components must be
linked together in a "daisy chain. " Connect the IR OUT
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 1: Use high-quality, shielded audio intercon-
nect cable from the AVR 635's location to the remote
room. In the remote room, connect the interconnect
cable to a stereo power amplifier. The amplifier will be
connected to the room's speakers. At the AVR 635,
plug the audio interconnect cables into the Multiroom
Audio Outputs j on the AVR 635's rear panel.
INSTALLATION AND CONNECTIONS
INSTALLATION AND CONNECTIONS
Option 2: Connect the Multiroom Audio Outputs
j on the AVR 635 to the inputs of an optional stereo
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-
fiers. To use the internal amplifiers to power a remote
zone, connect the speakers for the remote room loca-
tion to the Surround Back/Multiroom Speaker
Outputs ‚. 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. Alter-
natively, 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 ben-
efits of remote zone operation without the need for an
external power amplifier.
To use the AVR 635 with an approved A-BUS prod-
uct, simply connect it to the AVR 635 using standard
Category 5 wiring that is properly rated for the specific
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.
RS-232 Connections
The AVR 635 is equipped with an RS-232 Serial
Connection Port e that may be used for two pur-
poses. When the port is connected to a compatible,
optional, external computer, keypad or control system,
the AVR 635 is capable of bi-directional communica-
tions that enable the external system to control the
AVR, and for the AVR to report status and handshake
data back to the controller. Use of the RS-232 port for
this type of control requires specific technical knowl-
edge, and we recommend that any connection and
