Harman Kardon AVR 660/230 Service Manual

10REAR-PANEL CONNECTIONSHDMI Inputs and Output: HDMI (High-Definition Multimedia Interface)is a connection for transmitting digital audio and video signals betweendevices. Connect up to four HDMI-equipped source devices to the HDMI inputsusing a single-cable connection.When you connect the HDMI Output to your video display, the AVR 760/AVR 660 will automatically transcode analog video signals to the HDMIformat, upscaling to as high as 1080p.NOTES: When connecting a DVI-equipped display to one of the HDMIOutputs:Use an HDMI-to-DVI adapter.•Make sure the display is HDCP-compliant. If it isn’t, do not connect it to•an HDMI Output; use an analog video connection instead.Always make a separate audio connection.•Analog 1 – 5 Inputs: Connect the left and right analog audio outputs ofa source device to any of these inputs. These inputs may be paired with anyvideo inputs.NOTES:The Analog 3 and 4 inputs are each associated with a set of outputs.Consider using these connectors for an audio or video recorder.You may optionally connect a source to both an analog and digital audioinput. This is useful for making recordings, for multizone applications orsimply as a backup.Analog 3 and 4 Outputs: Connect either of these analog audio outputsto the analog audio inputs of a recording device. A signal is available at theseoutputs whenever an analog audio source is playing.Zone 2 Audio Outputs: Connect these jacks to an external amplifier topower the speakers in the remote zone of a multizone system.Subwoofer 1 and 2 Outputs: If you have a powered subwoofer witha line-level input, connect it to the Subwoofer 1 Output. For improvedperformance, connect a second powered subwoofer to the Subwoofer 2Output (Subwoofer 2 on AVR 760 only).The Bridge II Input: Connect the included Harman Kardondocking station to this input for use with most docking iPod models, 4G andlater (not included). Turn the receiver off (Standby mode) when connectingThe Bridge II.Fan Vents: This area contains vents used by the AVR 760/AVR 660’s fanto cool the system. Maintain a clearance of at least 8 cm from the nearestsurface to avoid overheating the unit. It is normal for the fan to remain off atmost normal volume levels. An automatic temperature sensor turns the fanon only when it is needed.IMPORTANT NOTE: Never block the fan vents, as doing so could allowthe AVR to overheat to dangerous levels.Zone 2 Video Output: Connect this composite video jack to a videodisplay located in the remote zone of a multizone system. When themultizone system is in use, viewers in the remote zone will be able to see theAVR’s on-screen text menus and any available source video, as long as thesource is connected to a Composite Video Input, and that input is specified forthat source in the Zone 2 Video setting of the Info Settings menu (AVR 760only).Composite and S-Video 1, 2 and 3 Video Inputs: Use these jacksto connect your video-capable source components (e.g., VCR, DVD player,cable TV box) to the receiver. Use only one type of video connection for eachsource.Composite and S-Video 2 Outputs: Connect one of these analogvideo outputs to the composite or S-video inputs of a recording device.A signal is available at these outputs whenever an analog video source isplaying.Composite and S-Video Monitor Outputs: If any of your sourcesuse composite or S-video connections, connect one or both of these monitoroutputs to the corresponding inputs on your video display. If your videodisplay is equipped with HDMI or component video inputs, these connectionsare unnecessary, as the AVR 760/AVR 660 will convert the composite orS-video source signal to the correct format for a single video-cable connectionto the TV.Component Video 1, 2 and 3 Inputs: If a video source has analogcomponent video (Y/Pb/Pr) capability, and if you are not using an HDMIconnection, connect the component video outputs of the source to one of thesets of component video inputs. Do not make any other video connections tothat source.Component Video Monitor Outputs: If you are using one of theComponent Video Inputs and your television or video display is component-video-capable (but does not have HDMI), connect these jacks to the videodisplay.NOTES:Due to copy-protection restrictions, there is no output at the•Component Video Monitor Outputs for copy-protected sources.Composite and S-video signals are upscaled to as high as 1080i and•available at these outputs. If your video display’s best connection iscomponent video, it is the only video connection required from the AVRto the display.AM and FM Antenna Terminals: Connect the included AM and FMantennas to their respective terminals for radio reception.Preamp Outputs: Connect these jacks to an external amplifier if morepower is desired. The Surround Back/Zone 2 Preamp Outputs may be usedwith an external amplifier to power the remote zone of a multizone system.A-BUS Port: Use a Category 5/5e cable to connect this port to optionalA-BUS equipment for multizone operation. When the A-BUS system is used, itis possible to have a full 7.2-channel system in the main listening room at thesame time the multizone system is in use.Front, Center and Surround Speaker Outputs: Use two-conductor speaker wire to connect each set of terminals to the correctspeaker. Remember to observe the correct polarity (positive and negativeconnections).Surround Back/Zone 2 Speaker Outputs: These speaker outputsare used for the surround back channels in a 7.2-channel home theater, ormay be reassigned to a remote room for multizone operation.Switched AC Accessory Outlet: You may plug the AC power cord ofone source device into this outlet, and it will turn on whenever you turn onthe receiver. Do not use a source that consumes more than 50 watts of power.AC Power Input: After you have made all other connections, plug the ACpower cord into this receptacle and into an unswitched wall outlet.A-BUS Power Input: When using optional A-BUS equipment, connect anoptional A-BUS power supply to this port.AVR 660 -760, 230V Service ManualPage 11 of 264
