The AVR 7300 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.

Important Note for the Use of 
SCART-Cinch Adapters:
When video sources are connected to the TV
directly with a SCART cable, specific control
signals apart from Audio/Video signals will be
fed to the TV. These specific signals are: With all
video sources, the signal for automatic input
selection that switches the TV automatically to
the appropriate input as soon as the video
source is started. And with DVD players, the
signals automatically turning the TV to 4:3/16:9
format (with 16:9 TVs or with 4:3 TVs with
selectable 16:9 format) and turning the RGB
video decoder of the TV on or off, depending on
the DVD player´s setting. With any adapter cable,
these control signals will be lost and the
appropriate setting of the TV must be made
manually.

Note for RGB signal with SCART:
If you use a unit providing RGB signals on a
SCART output (as e.g. most DVD players do) and
you want to use that RGB signal, this SCART
output must be connected directly to your TV.
Although the AVR can switch three-way video
signals (like component signals Y/Pb/Pr), most
TVs need separate sync signals for RGB (also
with SCART) that cannot be switched and pro-
vided by the AVR.
RGB signals can be pathed through the AVR only
when no separate sync signal is needed (see last
”Video Connection Note” on page 16).
