REAR PANEL CONNECTIONS 9

 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.

! 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.

" Preamp Outputs: Connect these jacks to
an optional, external power amplifier for appli-
cations where higher power is desired.

# Video 2 Video Outputs: Connect these
jacks to the RECORD/INPUT composite or 
S-Video jacks on a second VCR.

$ Video 3 Video Inputs: Connect these jacks
to the PLAY/OUT composite or S-Video jacks on
any video source.

% Video 3 Audio Inputs: Connect these jacks
to the PLAY/OUT audio jacks on any audio or
video source.

& Video 2 Audio Outputs: Connect these
jacks to the RECORD/INPUT audio jacks on a
VCR or any Audio recorder.

' 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.

( 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 17 for more information on
A-BUS.

) 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.

* Fan Vents: These ventilation holes are the
output of the AVR’s airflow system. To ensure
proper operation of the unit and to avoid possi-
ble damage to delicate surfaces, make certain
that these holes are not blocked and that there
is at least three inches of open space between
the vent holes and any wooden or fabric surface.

+ 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

! including the carrier

frequency that is removed from signals at the
Remote IR Output

. Use this output to

extend IR remote signals to the input of compat-
ible 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 manu-
facturer of the external equipment you wish to
control.

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 340, you may use either a composite or 
S-video connection, but not both.
