Multiroom Operation - Harman Kardon AVR 645 Owner's Manual

Multiroom Operation

Multiroom Operation
The AVR is fully equipped to operate as the con-
trol center for a complete multiroom system that
is capable of sending one source to a second
zone in the house while separate source is
listened to in the main room. In addition to
providing for control over the selection of the
remote source and its volume, the AVR offers a
comprehensive range of options for powering the
speakers in the second zone.
• Using the line-level Multiroom Audio
Outputs , the selected source may be fed to
optional, external power amplifiers that may be
matched to the specifics of the installation.
• When the main room system is configured for
5.1 operation, the Surround Back Left/Right
amplifier channels may be used to power the
remote zone so that no additional amplifiers are
required.
• Using built-in A-BUS/ technology,
READY ®
optional A-BUS modules may be connected to
the AVR via a single Category Five wire, so that
remote zone speakers may be powered directly
from the module or keypad without the need for
additional power, IR sensor or volume control
wires to be run to the second zone.
In addition, the AVR includes a remote IR sensor
input so that remote control commands from the
Zone II remote included with the unit may be
transmitted to the unit, while standard IR
input/output jacks allow the remote zone's
commands to be sent to compatible IR-controlled
source devices.
Installation
Although simple remote room systems may be
installed by the average do-it-yourself hobbyist,
the complexity of your multizone/multiroom
system involves running wires inside of walls
where the services of a specially trained installer
may be required. Regardless of who does the
work, please remember that local building codes
may govern in-wall electrical work, including
proper specification of any wiring used and the
way in which it is connected. You are responsible
for making certain that all Multiroom installation
work is done properly and in compliance with all
applicable codes and regulations.
For standard installations, follow the instructions
shown on page 16 and 18 for the connection of
speaker wire and IR remote wiring to the AVR.
For installations where the Surround Back
Left/Right amplifier channels are used to power
the remote zone, make certain that the system is
configured for that type of operation, as shown
on page 49.
For installations where A-BUS modules are used,
follow the instructions provided with the A-BUS
remote modules or keypads.

available through the Harman Kardon

RS-232 Control
The AVR is rare among A/V receivers in that it
provides the capability for full remote control
from compatible computers or specialized remote
control systems. RS-232 programming requires
specialized programming knowledge and for that
reason we recommend that it only be done by
qualified installers.
NOTE: The RS-232 port on this product is
for use by authorized service personnel
ONLY.
For more information on using the RS-232 port
for remote control, visit the Harman Kardon Web
site at
www.harmankardon.com
or contact our customer service department.
Multiroom Setup
Once the audio and IR link connections have
been made, the AVR needs to be configured for
multiroom operation using the steps below. Press
the OSD button to bring the

Surround Amplifier Channel Assignment
The AVR is equipped with seven full-power
amplifier channels to allow for complete
7.1-channel operation without the need for
additional external amplifiers. However, in some
installations you may wish to use the traditional
5.1-channel configuration for the main listening
room, which allows the surround back left/right
amplifier channels to be used to power speakers
placed in a remote zone location.
If you wish to use the Surround Back channel
amplifiers to power the remote zone, you must
