20 INSTALLATION AND CONNECTIONSSystem and Power ConnectionsThe AVR 445 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.In this 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 or an amplifier.The remote room IR receiver (this can be anoptional IR receiver or any other remotableHarman Kardon device in the remote room withIR sensor integrated) should be connected to theAVR via standard coaxial cable. Connect theRemote IR Output of the device or of theoptional sensor with the Multiroom IR Inputjack on the AVR’s rear panel.If other Harman Kardon compatible source equip-ment is part of the main room installation, theRemote IR Output jack on the rear panelshould be connected to the IR IN jack on thatsource device. This will enable the remote roomlocation to control source equipment functions.When a remote IR sensor is used to control non-Harman Kardon source equipment, we recom-mend that you make a direct connection or usean optional, external IR “blaster” connected tothe Remote IR Carrier Output Jack ,. If youare in doubt as to which IR Output jack to usefor the equipment in your system, contact yourdealer or installer, or the manufacturer’s supportsite and ask whether the unit to be controlleduses “full carrier” or “stripped” carrier IRcommands. When “full carrier commands” areused, make the connection to the Remote IRCarrier Output Jack ,. Otherwise, make theconnection to the Remote IR Output Jack as noted above.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 ConnectionsDepending on your system`s requirement anddistance from the AVR to the remote room, threeoptions are available for audio connection:Option 1: Use high-quality, shielded audio inter-connect phono cable from the AVR’s location tothe remote room. In the remote room, connectthe interconnect cable to a stereo power amplifi-er. The amplifier will be connected to the room’sspeakers. At the AVR, plug the audio interconnectcables into the Multiroom Output Jackson the AVR’s rear panel.Option 2: Place the amplifier that will providepower to the remote location speakers in thesame room as the AVR, and connect theMultiroom Output jacks on the rear panelof the AVR to the audio input of the remote roomamplifier. Use the appropriate speaker wire toconnect the optional power amplifier to theremote speakers. High-quality wire of at least2.5 mm 2 is recommended for long multiroomconnections.Option 3: Taking advantage of the AVR’s built-inseven-channel amplifier, it is possible to use twoof the amplifier channels to power speakers inthe remote room. When using this option you willnot be able to use the full 7.1-channelcapabilities of the AVR in the main listeningroom, but you will be able to add anotherlistening room without additional external poweramplifiers. To use the internal amplifiers to powera remote zone, connect the speakers for theremote room location to the SurroundBack/Multiroom Speaker Outputs '. Beforeusing the remote room you will need to configurethe amplifiers for surround operation bychanging a setting in the Multiroom menu,following the instructions shown on page 47.NOTE: For all options, you may connect anoptional IR sensor (Harman Kardon He 1000) inthe remote room to the AVR via an appropriatecable. Connect the sensor’s cable to theMultiroom IR Input on the AVR and usethe Zone II remote to control the room volume.Alternatively, you may install an optional volumecontrol between the output of the amplifiers andthe speakers.A-BUS Installation ConnectionsThe AVR is among the very few receiversavailable today that offers built-in A-BUS/READY ®operation. When used with an optional A-BUSkeypad or control module, you have all thebenefits of remote zone operation without theneed for an external power amplifier.To use the AVR with an approved A-BUS product,simply connect the keypad or module that is inthe remote room to the AVR using standard“Category 5” wiring that is properly rated for theinwall use specific to the installation. Terminatethe wiring at the receiver end to a standardRJ-45 jack in compliance with the instructionsfurnished with the A-BUS module.No further installation or adjustment is needed,as the A-BUS connector on the AVR routes thesignals in and out of the keypad to their properdestination for power, signal source and control.The output fed to the A-BUS jack is determinedby the AVR’s multiroom system, and the menusmay be used as is.RS-232 ConnectionsThe AVR is equipped with an RS-232 SerialConnection Port ) that may be used for twopurposes. When the port is connected to acompatible, optional, external computer, keypador control system the AVR is capable ofbi-directional communications that enable theexternal system to control the AVR, and for theAVR to report status and handshake data back tothe controller. Use of the RS-232 port for thistype of control requires specific technicalknowledge, and we recommend that any connec-tion and programming for control be made by atrained installer or technician familiar with theequipment being used.The physical connection to the AVR’s RS-232 portis a standard D-9 connection but to assurecompatible and proper operation, specificsoftware commands and pin wiring schemes maybe required.Installation and Connections
