18 INSTALLATION AND CONNECTIONSSystem and Power ConnectionsThe AVR 7000 is designed for flexible use withmultiroom systems, external control componentsand power amplifiers.Main Room Remote Control ExtensionIf the receiver is placed behind a solid or smokedglass cabinet door, the obstruction may preventthe remote sensor from receiving commands. Inthis event, the remote sensor of any HarmanKardon or other compatible device, not coveredby the door, or an optional remote sensor maybe used. Connect the Remote IR Output ofthat device or the output of the remote sensor tothe Remote IR Input jack c.If other components are also prevented fromreceiving remote commands, only one sensor isneeded. Simply use this unit’s sensor or a remoteeye by running a connection from the RemoteIR Output jack a to the Remote IR Inputjack on Harman Kardon or other compatibleequipment.NOTE: All remotely controlled components mustbe linked together in a daisy chain. Connect theIR OUT jack of one unit to the IR IN of the nextto establish this chain.Multiroom IR LinkThe key to remote room operation is to link theremote room to the AVR 7000’s location withwire for an infrared receiver and speakers or anamplifier. The remote room IR receiver (this can bean optional IR receiver or any other remotableHarman Kardon device in the remote room withIR sensor integrated) should be connected to theAVR 7000 via standard coaxial cable. Connect theRemote IR Output of the device or of theoptional sensor with the Multiroom IR Inputjack b on the AVR 7000’s rear panel.If other Harman Kardon compatible sourceequipment is part of the main room installation,the Remote IR Output jack a on the rearpanel should be connected to the IR IN jack onthat source device. This will enable the remoteroom location to control source equipment func-tions in addition to the remote room input andvolume.Multiroom Audio/Video ConnectionsDepending on the distance from the AVR 7000to the remote room, two options (A and B) areavailable for audio connection:A. Use high-quality, shielded stereo audio inter-connect cable with phono plugs on both endsfrom the AVR 7000’s location to the remoteroom. At the remote room, connect the intercon-nect cable to a stereo power amplifier. Theamplifier will be connected to the room’s speak-ers. No volume control is required, as the AVR7000 and the remote IR link will provide thatfunction. At the AVR 7000, plug the audio inter-connect cables into the Multi-Room Outputjacks d on the AVR 7000’s rear panel.NOTE: The remote power amplifier must have sig-nal sensing capability or be left on constantly toassure automatic operation at the remote room.B. Place the amplifier that will provide power tothe remote location speakers in the same roomas the AVR 7000, and connect the MultiroomOutput jacks d on the rear panel of the AVRto the audio input of the remote room amplifier.Use the appropriate speaker wire to connect theoptional power amplifier to the remote speakers.High-quality wire of at least 2.5 mm2 is recom-mended for long multiroom connections.The AVR 7000’s multiroom system is also capa-ble of sending either S-Video or standard com-posite video to the remote room location.Connect the video feeds for the remote locationto the Multiroom Output d video jacks. Notethat standard S-Video cables may not provideacceptable signal quality when used for runslonger than 10 m. Consult your dealer orinstaller for additional cable options for S-Videoapplications. When running longer lengths ofcomposite video cable for multi-room applica-tions, we recommend that dual shield or quadshield RG-6 cable be used.IMPORTANT NOTE: Any cables run inside wallsshould carry any certification that is required bythe local building and electrical codes. To avoidinterference, audio and speaker cables should notbe parallel to, or run in the same conduits or pathwith, AC cables. If you have any questions aboutmultiroom wiring, consult your dealer, custominstaller or low-voltage electrical contractor.External Audio Power AmplifierConnectionsIf desired, the AVR 7000 may be connected tooptional, external audio power amplifiers orused with equalizers or speaker systems thatrequire connection between the preamp andamplifier sections of a receiver.To make these connections, remove the jumpersthat connect the Preamp Out jacks fl andAmplifier In jacks ⁄ for the channels to beused with external devices. Store the jumpers ina safe place so that the AVR may be used in itsnormal mode at a future date, if desired.When an external amplifier is used, connect thePreamp Out jacks fl to the inputs on theamplifier. When an equalizer or speaker proces-sor is used, connect the Preamp Out jacks flto the inputs of the processor, and connect theoutputs of the processor back to the AmplifierIn jacks ⁄ on the AVR. Note that when externalamplifiers or devices are used, the volume con-trol is still controlled by the AVR, although addi-tional volume controls on the external devicemay impact the volume settings and output lev-els from the AVR.Installation and Connections
