System and Power Connections

The AVR 245 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, the remote sensor of any
Harman Kardon or other compatible device, not
covered by the door, or an optional remote
sensor may be used. Connect the Remote IR
Output of that device or the output of the
remote sensor to the Remote IR Input 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.
Multiroom IR Link
The key to remote room operation is to link the
remote room to the AVR's location with wire for
an infrared receiver and speakers or an amplifier.
The remote room IR receiver (this can be an
optional IR receiver or any other remotable
Harman Kardon device in the remote room with
IR sensor integrated) should be connected to the
AVR via standard coaxial cable. Connect the
Remote IR Output of the device or of the
optional sensor with the Multiroom IR Input
jack on the AVR's rear panel.
If other Harman Kardon compatible source
equipment is part of the main room installation,
the Remote IR Output jack on the rear
panel should be connected to the IR IN jack on
that source device. This will enable the remote
room location to control source equipment
functions.
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.
16 INSTALLATION AND CONNECTIONS
Multiroom Audio Connections
Depending on your system`s requirement and
distance from the AVR to the remote room, three
options are available for audio connection:
Option 1: Use high-quality, shielded audio
interconnect phono cable from the AVR'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, plug the
audio interconnect cables into the Multiroom
Output Jacks on the AVR's rear panel.
Option 2: Place the amplifier that will provide
. power to the remote location speakers in the
same room as the AVR, and connect the
Multiroom Output jacks
of the AVR to the audio input of the remote
room amplifier. Use the appropriate speaker wire
to connect the optional power amplifier to the
remote speakers. High-quality wire of at least
2.5 mm 2 is recommended for long multiroom
connections.
Option 3: Taking advantage of the AVR'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 capa-
bilities of the AVR in the main listening room,
but you will be able to add another listening
room without additional external power ampli-
fiers. To use the internal amplifiers to power a
remote zone, connect the speakers for the
remote room location 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 Multiroom menu,
following the instructions shown on page 43.
NOTE: For all options, you may connect an
optional IR sensor (Harman Kardon He 1000) in
the remote room to the AVR via an appropriate
cable. Connect the sensor's cable to the
Multiroom IR Input on the AVR and use
the remote to control the room volume.
Alternatively, you may install an optional volume
control between the output of the amplifiers and
the speakers.
NOTE: The AVR 245's multiroom system is only
capable 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 13, make sure to
use both analog and digital audio connections
to ensure that the devices will be available to
the multiroom system.
AC Power Connections
This unit is equipped with one accessory AC out-
lets. It may be used to power Accessory devices,
but it should not be used with high-current draw
equipment such as power amplifiers. The total
power draw to the Switched
not exceed 50 watts.
The Switched
when the unit is on completely. This is recom-
mended 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 outlets, and cannot be fully turned on
on the rear panel using the outlet alone without a remote control
command.
The AVR draws significantly more current than
other household devices such as computers that
use removable power cords. For that reason, it is
important that only the cord supplied with the
unit (or a direct replacement of identical
capacity) be used.
Once the power cord is connected, you are
almost ready to enjoy the AVR 245's incredible
power and fidelity!
