INSTALLATION AND CONNECTIONS 19ENGLISHInstallation and ConnectionsSystem and Power ConnectionsThe AVR 247 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 anyHarman Kardon or other compatible device, notcovered by the door, or an optional remotesensor may be used. Connect the Remote IROutput of that device or the output of theremote sensor to the Remote IR Input jack !.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 to the Remote IR Inputjack on Harman Kardon or other compatibleequipment.Multiroom IR LinkThe key to remote room operation is to link theremote room to the AVR’s location with wire foran infrared receiver and speakers. The remoteroom IR receiver (this can be an optional IRreceiver) should be connected to the AVR viastandard coaxial cable. Connect the Remote IROutput of the device or of the optional sensorwith the Multiroom IR Input jack ' on theAVR’s rear panel.If other Harman Kardon compatible sourceequipment is part of the main room installation,the Remote IR Output jack on the rearpanel should be connected to the IR IN jack onthat source device. This will enable the remoteroom location to control source equipmentfunctions.NOTE: All remotely controlled components mustbe linked together in a “daisy chain”. Connectthe IR OUT jack of one unit to the IR IN of thenext to establish this chain.Multiroom Audio ConnectionsTaking advantage of the AVR’s built-in seven-channel amplifier, it is possible to use two of theamplifier channels to power speakers in theremote room. When using this option you willnot be able to use the full 7.1-channel capabili-ties of the AVR in the main listening room, butyou will be able to add another listening roomwithout additional external power amplifiers. Touse the internal amplifiers to power a remotezone, connect the speakers for the remote roomlocation to the Surround Back/MultiroomSpeaker Outputs . Before using the remoteroom you will need to configure the amplifiersfor surround operation by changing a setting inthe Multiroom menu, following the instructionsshown on page 45.NOTE: You may connect an optional IR sensor(Harman Kardon He 1000) in the remote roomto the AVR via an appropriate cable. Connect thesensor’s cable to the Multiroom IR Input 'on the AVR and use the remote to control theroom volume. Alternatively, you may install anoptional volume control between the output ofthe amplifiers and the speakers.NOTE: The AVR 247’s multiroom system is onlycapable of distributing analog audio sources tothe remote zone. Therefore, when connectingyour digital audio equipment (e.g. CD or DVDplayers) as described on page 16, make sure touse both analog and digital audio connectionsto ensure that the devices will be available tothe multiroom system.AC Power ConnectionsThis unit is equipped with one accessory ACoutlet. It may be used to power accessorydevices, but should not be used with high-currentdraw equipment such as power amplifiers. Thetotal power draw to the Switched Outlet should not exceed 50 watts.The Switched outlet will receive power onlywhen the unit is on completely. This is recom-mended for devices that have no power switchor a mechanical power switch that may be left inthe “ON” position.NOTE: Many audio and video products go into aStandby mode when they are used withswitched outlets, and cannot be fully turned onusing the outlet alone without a remote controlcommand.The AVR draws significantly more current thanother household devices such as computers thatuse removable power cords. For that reason, it isimportant that only the cord supplied with theunit (or a direct replacement of identicalcapacity) be used.Once the power cord is connected, you arealmost ready to enjoy the AVR 247’s incrediblepower and fidelity!
