MULTIROOM OPERATION 35Multiroom OperationMultiroomThe AVR is fully equipped to operate as the con-trol center for a complete multiroom system thatis capable of sending one source to a secondzone in the house while separate source is lis-tened to in the main room. In addition to provid-ing for control over the selection of the remotesource and its volume, the AVR offers a com-prehensive range of options for powering thespeakers in the second zone.• Using the line-level Zone 2 Outputs ', theselected source may be fed to optional, externalpower amplifiers that may be matched to thespecifics of the installation (Zone 2 Outputs onAVR 355 only).• When the main room system is configured for5.1 operation, the Surround Back Left/Rightamplifier channels may be used to power theremote zone so that no additional amplifiers arerequired.• Using built-in A-BUS Ready technology,optional A-BUS modules may be connected tothe AVR via a single Category Five wire, so thatremote zone speakers may be powered directlyfrom the module or keypad without the need foradditional power, IR sensor or volume controlwires to be run to the second zone. (Please notethat the A-BUS functionality is featured in AVR355 only).In addition, the AVR includes a remote IR sensorinput so that remote control commands from theZone II remote included with the (AVR 355 only)or from the main remote when set to Zone 2with the slide Switch Z may be transmitted tothe unit, while standard IR input/output jacksallow the remote zone’s commands to be sent tocompatible IR-controlled source devices.InstallationAlthough simple remote room systems may beinstalled by the average do-it-yourself hobbyist,the complexity of your multizone/multiroom sys-tem involves running wires inside of walls wherethe services of a specially trained installer maybe required. Regardless of who does the work,please remember that local building codes maygovern in-wall electrical work, including properspecification of any wiring used and the way inwhich it is connected. You are responsible formaking certain that all Multiroom installationwork is done properly and in compliance with allapplicable codes and regulations.For standard installations, follow the instructionsshown on page 18-19 for the connection ofspeaker wire and IR remote wiring to the AVR.For installations where the Surround BackLeft/Right amplifier channels are used to powerthe remote zone, make certain that the system isconfigured for that type of operation, as shownbelow.For installations where A-BUS modules are used,follow the instructions provided with the A-BUSremote modules or keypads.Additional information will also be made avail-able through the Harman Kardon Web Site atwww.harmankardon.com.Multiroom SetupOnce the audio and IR link connections havebeen made, the AVR needs to be configured formultiroom operation using the steps below.Press the AVR button Y to bring the mainmenu to the screen. Press the ⁄/¤ Button Funtil the ZONE 2 menu line is highlighted inblue. Press the OK button X to enter the menu.Figure 18When the ZONE 2 menu appears, the bluecursor bar will be at the Status: Off line.Since this line is used to turn the system on andoff, do not make an adjustment here unless youwish to turn the system on at this time. To turnthe system on, press the OK Button X once, toturn it off again, press once more. If you do notwish to turn the system on at this time or to pro-ceed to the next step, press the ¤ Button Fonce so that the blue cursor bar is highlightingthe Source line.At the Source line, press the press the OKButton to cause the Source List to slide in fromthe right. Use the Up/Down Button F to selectthe source.. When the selection has been made,press the OK Button X to confirm your choice,and continue to the Volume line by pressingthe ¤ Button F.At the Volume line, press the ‹/› buttonsF or hold them pressed until the desired vol-ume level for the multi-room system is entered.DO NOT use the regular volume control knobsfor this setting.Surround Amplifier ChannelAssignmentThe AVR is equipped with seven full-poweramplifier channels to allow for complete7.1-channel operation without the need foradditional external amplifiers. However, in someinstallations you may wish to use the traditional5.1-channel configuration for the main listeningroom, which allows the surround back left/rightamplifier channels to be used to power speakersplaced in a remote zone location.If you wish to use the Surround Back channelamplifiers to power the remote zone, you mustchange a setting in the MULTIROOMSETUP menu. To make that change, first callup the menu system by pressing the AVRButton Y to bring the main menu (Figure 1) tothe screen. Next, press the ¤ Button F untilthe Zone 2 menu line is highlighted in blue.Press the OK Button X to enter the Zone 2menu.The Surround Back Amps line is used to assignthe surround back channels for multizone opera-tion. Select the Zone 2 setting when multizonelistening is desired. If the multizone system isnot in use, this setting may be changed to MainRoom to accommodate a 7.1-channel system.When the multiroom system is turned off, thisline will always display the MAIN setting. Whenthe multiroom system is turned on, this line willalways display the MULTI setting, reflecting thatthe surround back channels are always assignedto the remote zone when the multiroom systemis used.Remember that once this setting is made youwill not be able to take advantage of any of the6.1/7.1- channel decoding or processing modes,and no Surround Back speakers must beselected in the speaker setup procedure outlinedearlier. In addition the speakers used for theremote zone must be connected to theSurround Back/Multiroom SpeakerOutputs . The volume for these speakers isset by the multiroom system, as explainedabove.ENGLISH
