REAR-PANEL CONNECTIONSThe AVR 347 is Simplay HD-verified for compatibility via the HDMIconnection with other Simplay HD-verified products.CD and Tape Audio Inputs: These jacks may be used to connectaudio-only source components (e.g., CD player, tape deck). Do notconnect a turntable to these jacks without a phono preamp.Tape Outputs: These jacks may be used to connect a CDR oranother audio-only recorder.Coaxial and Optical Digital Audio Inputs: If a source hasa compatible digital audio output, connect it to one of these jacksfor improved audio performance. Use only one type of digital audioconnection for each source.Coaxial and Optical Digital Audio Outputs: If a source is alsoan audio recorder, you may connect a compatible digital audio outputto the recorder’s input for improved recording quality.The Bridge/DMP Input: Connect the optional Harman Kardonto this input for use with your iPod (not included). Makesure the receiver is turned off (in Standby mode) when connectingThe Bridge.6-/8-Channel Inputs: Connect the multichannel analog audiooutputs of a DVD-Audio, SACD™, Blu-ray Disc™ or HD-DVD™ player(or any other external decoder) to these jacks to enjoy these proprietaryformats.NOTE: When an HD-DVD or Blu-ray Disc player has anonboard digital decoder, it is not necessary to connect it tothe 6-/8-Channel Analog Audio Inputs. Only a digital audioconnection (HDMI, coaxial or optical) is needed.Component Video Inputs: If both a video source (e.g., DVDplayer or HDTV tuner) and your television or video display have analogcomponent video (Y/Pb/Pr) capability and if you are not using HDMIconnections for the device, then you may connect the component videooutputs of the source to one of the two component video inputs. Donot make any other video connections to that source.Component Video Monitor Outputs: If you are using one ofthe Component Video Inputs and your television or video display iscomponent-video-capable and if you are not connecting the HDMIoutput to our display, you may connect these jacks to the correspondinginputs on your video display.NOTES:• Due to copy-protection restrictions, there is no output at theComponent Video Monitor Outputs for copy-protectedsources.• High-resolution 1080i and 1080p video signals are notavailable at the HDMI Output, and are downconverted to720p for the Component Video Outputs. If your source outputis analog high-resolution video, either use the ComponentVideo Outputs, lower the output resolution of your sourcedevice, or connect your source’s component video outputsdirectly to your video display.• Due to the design of some video displays, analog 480p or720p component video source signals may produce artifactswhen used with the AVR’s analog video outputs (composite,S-video or component video). If this occurs, try changing theVideo Mode setting in the INPUT SETUP menu, or connectingthe source device’s video output directly to your video display.However, for best results, we recommend you considerupgrading to an HDMI-capable video display.RS-232 Serial Port: This specialized connector may be used withyour personal computer in case Harman Kardon offers a softwareupgrade for the receiver at some time in the future.RS-232 Mode: Leave this switch popped out in the Operate positionunless the AVR 347 is being upgraded.RS-232 Reset: This switch is only used during a software upgrade.A standard processor reset is performed by pressing and holding thefront-panel Tone button.Switched AC Accessory Outlet: You may plug the AC powercord of one source device into this outlet, and it will turn on wheneveryou turn on the receiver. Do not use a source that consumes more than50 watts of power.AC Power Cord Input: After you have made all other connections,plug the AC power cord into an unswitched outlet. Plug the female endof the cord into this receptacle, which conveniently allows you to installall wiring ahead of time.The BridgeTMAVR347 harman/kardon9
