System And Power Connections - Harman Kardon AVR 340 Owner's Manual

INSTALLATION AND CONNECTIONS

System and Power Connections

The AVR 340 is designed for flexible use with multi-
room system and external control components.
Remote Infrared (IR) Control of the AVR or
Source Devices
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 ª jack.
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 to
the Remote IR Input jack on Harman Kardon or other
compatible equipment.
When controlling non-Harman Kardon source devices,
the device may require the full carrier signal embed-
ded within the IR command, rather than the "stripped"
signal used by Harman Kardon and many other
devices. In these cases you may need to connect the
Remote IR Carrier Output § to the remote IR input
of your device (or to an optional, external IR "blaster"),
rather than using the standard Remote IR Output
Jack ‚. If you are in doubt as to which IR Output
jack to use for the equipment in your system, contact
your dealer or installer, or consult 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 Remote IR Carrier Output §.
Otherwise, make the connection to the Remote IR
Output Jack ‚.
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 340 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 340'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 340,
plug the audio interconnect cables into the Multiroom
Audio Outputs ™ on the AVR 340's rear panel.

Option 2: Connect the Multiroom Audio Outputs
™ on the AVR 340 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 340'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 340 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 operation
by changing a setting in the MULTI ROOM
SETUP menu, following the instructions shown
on page 46.
NOTE: The AVR 340's multiroom system is only capa-
ble of distributing analog audio sources to the remote
zone. Therefore, when connecting your digital audio
equipment (e.g., CD or DVD players) as described on
page 16, make sure to use both analog and digital
audio connections to ensure that the devices will be
available to the multiroom system.
IR Control From the Remote Room
For all options, you may connect an optional IR sensor
in the remote room to the AVR 340 via an appropriate
cable. Connect the sensor's cable to the Multiroom
IR Input ∞ on the AVR 340 and use the Zone II
(or main) remote to control the room volume and any
source devices connected to the Remote IR Output
Jack ‚ or to the Remote IR Carrier Output Jack
§ as described above. Alternatively, you may install
an optional volume control between the output of the
amplifiers and the speakers, which will only enable you
to adjust the volume of playback in the remote room.
A-BUS ® Installation Connections
The AVR 340 is among the few receivers available
that offer built-in A-BUS/ operation. When used
READY
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 340 with an approved A-BUS prod-
uct, simply connect it to the AVR 340 using 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.
You may connect a single A-BUS module to the
AVR 340 with no further equipment needed. If you
wish to connect more than one A-BUS module, an
optional, external A-BUS hub may be used to provide
that capability.
Contact your dealer or visit www.harmankardon.com
for more information on other A-BUS products
available from Harman Kardon. No further installation
or adjustment is needed, as the A-BUS jack on the
AVR 340 routes the signals to their proper destination.
The output fed to the A-BUS jack is determined by
the AVR 340's multiroom system and menus.
If the A-BUS module is equipped with an IR sensor,
you may use the Zone II or main remote to control the
room volume and any source devices connected to
the Remote IR Output Jack ‚ or to the Remote
IR Carrier Output Jack § as described above.
AC Power Connections
This unit is equipped with two accessory AC outlets.
They may be used to power accessory devices, but
they should not be used with high-current-draw equip-
ment, such as power amplifiers. The total power draw
to each outlet may not exceed 100 watts.
The Switched AC Accessory Outlet b will receive
power only when the unit is on. This is recommended
for devices that have no power switch or a mechanical
power switch that may be left in the "ON" position.
NOTE: Many audio and video products go into a
Standby mode when they are used with switched out-
lets, and cannot be fully turned on using the outlet
alone without a remote control command.
The Unswitched AC Accessory Outlet c will
receive power as long as the unit is plugged into a
powered AC outlet.
Once the AC Power Cord a is connected, you are
almost ready to enjoy the AVR 340's incredible power
and fidelity!
