INSTALLATION AND CONNECTIONS

INSTALLATION AND CONNECTIONS
7. The default audio connection for a DVD player is
to link the coaxial digital audio output on the DVD
player to the Coaxial 1 Digital Audio Input
but you may also make a connection to either the
Coaxial or Optical digital inputs, or the
Analog DVD Audio Inputs
the assignment in the IN/OUT SETUP
menu as described on page 24, or by using the
front-panel Digital Input Selector F.
8. To use a portable audio/video product such as a
camcorder, media player or digital still camera with
the AVR, or connect a video game console or other
source that may not always be connected to the
AVR, connect the video outputs of the source to the
Video 4 Input/Output Jacks N, behind the
Front-Panel Door . If the source has digital
audio outputs, connect them to the Optical 4
Digital Input K or the Coaxial 4 Digital Jack M.
CONNECTION NOTES:
• When making connections to the Component
Video Inputs or the Coaxial
digital audio inputs, it is a good idea to make
note of which jacks are connected to which
source, using the Worksheet in the Appendix. This
will help simplify the configuration process.
• When connecting a source device such as a
cable set-top box where the audio streams may
change between digital and analog as you
change channels, we recommend that you make
both analog and digital connections. The AVR's
Auto Poll feature will automatically sense when
the digital stream is replaced by an analog output
and switch the input accordingly. (See page 24
for more information on the Auto-Poll feature.)
This dual connection is not required for sources
(such as DVD players or video games) that always
output a digital stream.
9. Connect the AVR to your video display using one of
the following connections:
• If you have a video display with an HDMI or DVI
input, make the connection using the HDMI
Output , as described in the next section.
• If your video display has component video
inputs (Y/Pr/Pb), connect the Component
Video/Monitor Outputs
• If your display does not have digital or compo-
nent video inputs, connect the Video Monitor
Output on the AVR to the matching input on
your display. Only one connection is needed, and
S-video is the higher quality signal.
HDMI Connections
HDMI ™ is the abbreviation for High-Definition Multimedia
Interface, which is quickly becoming the standard connec-
tion point between advanced video/audio source products
and displays, particularly for high-definition video signals.
HDMI is a digital connection, eliminating the need to con-

vert signals back and forth from digital to analog to deliver
a higher quality signal when used with digital sources. The
, signals carried on HDMI may, but do not always, include
audio, offering the possibility of a complete one-wire con-
nection from a source to the AVR. However, it is important
. You may change to note that there are a number of different versions of
the HDMI standard in use. Before connecting any HDMI
products to your AVR, it is helpful to find out in advance
their level of HDMI connectivity.
Some source or display components in your system
may use DVI (Digital Video Interface) for digital video
connections. DVI carries the same digital video signals
as HDMI but uses a larger connector and does not
transport audio or control signals. In most cases, you
may mix and match DVI and HDMI digital video con-
nections by using optional connector adapters. Note,
however, that some DVI-equipped video displays are
not compatible with the HDCP copy protection coding
that is increasingly carried with signals connected
via HDMI. If you have an HDMI source and a DVI-
equipped display, you may occasionally be unable to
or Optical
view a program if the display does not include HDCP.
This is not the fault of the AVR or your source; it sim-
ply indicates that the video display is not compatible.
HDMI Input Connections
The different "Version" levels of HDMI define which
type of audio signals it is compatible with. Based on
the lowest level of HDMI among your sources, the
connections to the AVR should be made as follows:
• HDMI 1.0 sources carry digital video and multi-
channel or 2-channel PCM audio signals only.
Connect the HDMI output of a 1.0 source to either
of the HDMI Inputs

tichannel analog audio outputs, connect them to the

source, particularly a DVD player, make certain
that the menus in the source device are set to
"Bitstream Out" or "Original" so that 5.1 digital audio
is available. If you find that 5.1 Dolby Digital or DTS
audio is not available on the HDMI connection, it
will be necessary to make an additional connection
between the source and the AVR 645 to either the

the digital video. If you have an HDMI 1.1-equipped
product, the only connection needed for listening

source to either of the HDMI Inputs
AVR. If the player has SACD capability, you will need
to connect the analog outputs of the source to the
8-Channel Direct Inputs
• HDMI 1.2 (and higher) sources should be connected
as shown above for HDMI 1. 1 .
• It is not possible to feed an analog audio or com-
posite or S-video signal to a recorder or the AVR's

multizone system when an HDMI input is in use. If an
HDMI-equipped source also has analog audio and
video outputs, connect them to the Video 2 or Video 3
Video and Audio inputs.
• In some instances, HDMI-equipped sources will not
permit more than one video output at a time, and
thus you cannot use the same source in the main
listening room, and with the recorder at the same
time. This is not a fault of the AVR, but rather a
function of the content-protection systems that
are part of the HDMI standard.
HDMI Output Connections
Connect the HDMI Output to an HDMI input on
your video display. Thanks to the AVR 645's video
processing system, all video input signals are converted
to an HDMI output, so only one connection is required
between the AVR and your display.

System and Power Connections

The AVR 645 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
IR Input fl.
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 IR Output ‹ to the Remote IR
Input jack on Harman Kardon or other compatible
equipment.
If other Harman Kardon-compatible source equipment
is part of the main room installation, the IR Output
Jack ‹ on the rear panel should be connected 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 non-
Harman Kardon source equipment, we recommend
that you make a hard-wire connection or use an
optional, external IR "blaster" connected to the Full
Carrier IR Output . If you are in doubt as to which
IR Output jack to use for the equipment in your sys-
tem, contact your dealer or installer, or the manufac-
turer's support site and ask whether the unit to be
controlled uses "full carrier" IR commands. When "full
carrier" commands are used, make the connection to
the Full Carrier IR Output ¤. Otherwise, make the
connection to the IR Output ‹.
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.
