Rear Panel Connections
Surround Back/Multiroom Speaker Outputs: These speaker terminals are normally used to power the surround back left/surround back right speakers in a 7.1 channel system. However,they may also be used to power the speakers in a second zone, which will receive the output selected for a multiroom system.
To change the output fed to these terminals from the default of the Surround Back speakers to the Multiroom Output, you must change a setting in the MULTIROOM MENU of the OSD system. See page 35 for more information on configuring this speaker output. In normal surround system use, the brown and black termi- nals are the surround back left channel positive
(+) and negative (–) connections and the tan and black terminals are the surround back right positive (+) and negative (–) terminals.
For multiroom use, connect the brown and black SBL terminals to the red and black connections on the left remote zone speaker and connect the tan and black SBR terminals to the red and black terminals on the right remote zone speaker.
Video 1 Video Outputs: Connect these jacks to the RECORD/INPUT composite or S-Video jack on a VCR.
Video 1 Video Inputs: Connect these jacks to the PLAY/OUT composite or S-Video jacks on a TV or other video source.
Optical Digital Inputs: Connect the optical digital output from a DVD player,HDTV receiver, the output of a compatible computer sound card playing MP3 files or streams, LD player,MD player or CD player to these jacks. The signal may be either a Dolby Digital signal, a DTS signal, a 2 channel MPEG 1 signal, or a standard PCM digital source.
Analog 4 Audio Inputs: Connect these jacks to the PLAY/OUT audio jacks on a TV or other audio or video source.
Video 2 Video Inputs: Connect these jacks to the PLAY/OUT composite or S-Video jacks on a second VCR or other video source.
Remote Input and Output: If the AVR’s front-panel IR sensor is blocked due to cabinet doors or other obstructions, an external IR sen- sor may be used. Connect the output of the sensor to the Remote IN jack.
The Output connection permits 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.
Zone 2 IR Input: Connect the outputof an IR sensor in a remote room to this jack to operate the AVR’s multiroom controlsystem.
!Preamp Outputs: Connect these jacks to an optional, external power amplifier for appli- cations where higher power is desired.
#HDMI Output: Connect this jack to the HDMI input on a compatible HDMI-equipped video display.
"Video 3 Video Inputs: Connect these jacks to the PLAY/OUT composite or S-Video jacks on any video source.
$Analog 3 Audio Inputs: Connect these jacks to the PLAY/OUT audio jacks on any audio or video source.
%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.
&Zone 2 Outputs (AVR 355 only): 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 18 for more information on A-BUS.
(Remote IR Carrier Output (AVR 355 only): The output of this jack is the full signal received at the Remote Sensor Window Ó 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 compatible products by direct connec- tion 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.
)Video 3 Component Video Inputs (AVR 355 only): These inputs may be used with any source device equipped with analog Y/Pr/Pb or RGB component video outputs. Do not use these inputs if HDMI connection is possible, use the HDMI inputs instead.
*A-BUS IR Out (AVR 355 only): This output sends out the remote signal received by an A- Bus unit. This makes it possible to connect other Harman Kardon products to the AVR via their "IR IN" jacks, controlling them from another room with an A-Bus unit.
+Main Power Switch: Press this button ON to apply power to the AVR. When the switch is ON, the unit is placed in a Standby mode, as indicated by the amber LED 3. This button MUST be ON to operate the unit. To turn the unit off completely and prevent the use of the remote control, this switch should be pressed OFF.
NOTE: This switch is normally left in the “ON” position.
With the AVR’s powerful processor,you may connect up to three HDMI-equipped source devices to the HDMI inputs using a single-cable connection, 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 digital 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 255/AVR 355, you may use either a com- posite or S-video connection, but not both.
