REAR PANEL CONNECTIONS 9 Preamp Outputs: Connect these jacks toan optional, external power amplifier for appli-cations where higher power is desired.) Surround Back/Multiroom SpeakerOutputs: These speaker terminals are normallyused to power the surround back left/surroundback right speakers in a 7.1 channel system.However, they may also be used to power thespeakers in a second zone, which will receive theoutput selected for a multiroom system.To change the output fed to these terminalsfrom the default of the Surround Back speakersto the Multiroom Output, you must change asetting in the Multiroom Menu of the OSD sys-tem. See page 42 for more information on con-figuring this speaker output. In normal surroundsystem use, the brown and black terminals arethe surround back left channel positive (+) andnegative (–) connections and the tan and blackterminals are the surround back right positive(+) and negative (–) terminals.For multiroom use, connect the brown and blackSBL terminals to the red and black connectionson the left remote zone speaker and connect thetan and black SBR terminals to the red and blackterminals on the right remote zone speaker. RS-232 Port: This jack may be used to con-trol the AVR 435 over a bi-directional RS-232serial control link to a compatible computer orprogrammable remote control system. Due tothe complexity of programming RS-232 com-mands we strongly recommend that connectionsto this port for control purposes be made by atrained and qualified technician. This jack mayalso link to a compatible computer to upgradethe software and operating system of theAVR 435 when appropriate upgrades areavailable.' Fan Vents: These ventilation holes are theoutput of the AVR’s airflow system. To ensureproper operation of the unit and to avoid possi-ble damage to delicate surfaces, make certainthat these holes are not blocked and that thereis at least three inches of open space betweenthe vent holes and any wooden or fabric surface. DVD Component Video Inputs: Theseinputs may be used with any source deviceequipped with analog Y/Pr/Pb or RGB compo-nent video outputs. The factory default is forthese jacks to be a linked to the DVD input, butyou may change the setting at any time throughthe IN/OUT SETUP menu. See page 15 formore information on configuring the componentvideo inputs. Remote IR Carrier Output: The output ofthis jack is the full signal received at theRemote Sensor Window ¯ or input throughthe Remote IR Input including the carrierfrequency that is removed from signals at theRemote IR Output . Use this output toextend IR remote signals to the input ofcompatible products by direct connection orthrough the use of optional, external IR“blasters”. If you are in doubt as to which of thetwo IR Output jacks to use, we recommend thatyou consult with your dealer or installer, or checkwith the manufacturer of the external equipmentyou wish to control.Rear Panel Connections
