10 REAR PANEL CONNECTIONS
Rear Panel Connections
U
Remote IR Output: This connection per-
mits the IR sensor in the receiver to serve other
remote controlled devices. Connect this jack to
the “IR IN” jack on Harman Kardon or other
compatible equipment.
V
Remote IR Input: If the AVR’s front-panel
IR sensor is blocked due to cabinet doors or
other obstructions, an external IR sensor may
be used. Connect the output of the sensor to
this jack.
W
Preamp Outputs: Connect these jacks to
an optional, external power amplifier for appli-
cations where higher power is desired.
X
HDMI Output: Connect this jack to the
HDMI input on a compatible HDMI-equipped
video display.
Y
Video 3 Video Inputs: Connect these jacks
to the PLAY/OUT composite or S-Video jacks on
any video source.
Z
Video 3 Audio Inputs: Connect these jacks
to the PLAY/OUT audio jacks on any audio or
video source.
a
HDMI Inputs: Connect the HDMI output of
video sources such as a DVD player, set-top box
or HDTV tuner to either of these jacks.
b
Multiroom Outputs: Connect these jacks
to an optional audio power amplifier to listen to
the source selected by the multiroom system in a
remote room.
c
A-BUS Connector: Connect this jack to an
optional A-BUS-certified remote room keypad or
amplifier to extend the multiroom capabilities of
your AVR. See page 21 for more information on
A-BUS.
d
Multiroom IR Input: Connect the output of
an IR sensor in a remote room to this jack to
operate the AVR’s multiroom control system.
e
Video 3 Component Video Inputs: These
inputs may be used with any source device
equipped with analog Y/Pr/Pb or RGB compo-
nent video outputs. The factory default is for
these jacks to be a linked to the Video 2 input,
but you may change the setting at any time
through the
INPUTSETUP menu. See page
24 for more information on configuring the
component video inputs.
f
Remote IR Carrier Output: The output of
this jack is the full signal received at the
Remote Sensor Window
Ú
or input through
the Remote IR Input
V
including the carrier
frequency that is removed from signals at the
Remote IR Output
U
. Use this output to
extend IR remote signals to the input of
compatible products by direct connection or
through the use of optional, external IR
“blasters”. If you are in doubt as to which of the
two IR Output jacks to use, we recommend that
you consult with your dealer or installer, or check
with the manufacturer of the external equipment
you wish to control.
With the AVR’s powerful processor, you may con-
nect up to two HDMI-equipped source devices to
the HDMI inputs using a single-cable connec-
tion, while benefiting from superior digital audio
and video performance. However, if your video
display is not HDMI-compatible, you will need to
connect the source device to one of the other
source inputs, selecting a coaxial or optical digi-
tal audio input and analog video input. See the
Connections and Installation sections for more
information.
If your video display has an HDMI input, but
some of your sources have only analog video
outputs, you may still rely on just the HDMI
video connection to your display; the AVR will
automatically transcode analog video signals to
the HDMI format.
NOTE ON VIDEO CONNECTIONS: When con-
necting a video source product such as a VCR,
DVD player, satellite receiver, cable set-top box,
personal video recorder or video game to the
AVR 347, you may use either a composite or
S-video connection, but not both.
