INSTALLATIONNOTE: The AVR 347 remote is preprogrammed to operate thetransport controls of Harman Kardon DVD players when the AVR,the Video 2 (cable/satellite) or the Video 3 (TV) source is selected.You may change this punch-through programming at any time.Step Nine – Remote IR Inputs and Output (Optional)The AVR 347 is equipped with a Remote IR Input, a Multiroom IR Inputand both full-carrier and stripped Remote IR Outputs to facilitate use ofyour system with a remote control in a variety of situations. See Figure 39.Figure 39 – IR Inputs and OutputsWhen the AVR 347 is placed in such a way that aiming the remote atthe front-panel IR sensor is difficult, such as inside a cabinet or facingaway from the listener, you may connect an external IR receiver, suchas the optional Harman Kardon HE 1000, to the Remote IR Input jack.When you are using the AVR 347 in multiroom mode, you may connectan optional IR receiver, keypad or other control device to the MultiroomIR Input for remote control of the AVR 347 (and any sources connectedto the AVR’s Remote IR Output) from the remote zone. Any signalstransmitted through the Multiroom IR Input will only control source selec-tion and volume for the remote zone. If a source device is being sharedwith the main listening area, then any control commands issued to thatsource will also affect the main room.If any of your source devices are equipped with a compatible Remote IRInput, you may use a 1/8" mini-plug interconnect cable (not included) toconnect the AVR’s Remote IR Output to the source device’s Remote IRInput, which will pass any applicable remote signals transmitted throughthe AVR to the source device. This enables you to control your sourceseven when the AVR itself is controlled via an external IR receiver.Check with the manufacturer of the source device for more informationon the type of IR signal expected. The AVR 347 will output a “strippedcarrier” IR signal through the Remote IR Output, but a full-carrier IRsignal is available at the Carrier Remote IR Output.To control more than one source device using the Remote IR Output,connect all sources in “daisy chain” fashion, with the AVR’s Remote IROutput connected to the first device’s Remote IR Input, that device’sRemote IR Output connected to the next device’s Remote IR Input, andso forth. Connect devices expecting a full-carrier IR signal to the CarrierRemote IR Output. Use the Remote IR Output for devices expecting astripped signal.Step Ten – Install a Multiroom System (Optional)The AVR 347 offers several methods of distributing music to other lis-tening areas in your home. As indicated in the subheading, installing amultiroom system is not required to enjoy the home theater experience.If you prefer not to install a multiroom system at this time, skip to StepEleven to turn on the AVR 347 and configure it.IMPORTANT SAFETY NOTE: Installing a multiroom systemvery often requires running various cables inside walls. Alwayscomply with the appropriate safety codes when installing con-cealed wiring. The AVR 347’s multiroom connections should beinstalled per the requirements of all applicable state and localbuilding codes, as well as NEC (National Electrical Code)requirements. Check with your local authorities as needed toensure that all wiring inside walls is installed in compliance withthe proper standards. Failure to do so may present a potentialsafety hazard. If you have any doubt about your ability to workwith electrical and telecommunications wiring, you are advisedto hire a professional licensed electrician or custom installer toinstall the multiroom system.1. Connect an external amplifier to the Multiroom Audio Outputs.See Figure 40.Figure 40 – Multiroom Audio OutputsIt is recommended that you place the amplifier in the same roomas the AVR 347 so that a shorter length of interconnect cable is usedwith a long run of speaker wire to the remote room, rather thanplacing the amplifier in the remote room, which necessitates a longrun of interconnect cable that would be subject to signal degradation.Depending on the number of channels available in your amplifier, youmay distribute the AVR 347’s analog audio signal to a single pair ofspeakers for 2-channel listening, to several pairs of speakers locatedin several different rooms, or when listening to mono FM radio, toindividual speakers placed in different rooms. (Use the Tuning ModeButton to select the mono mode for FM radio.)The advantage of using the Multiroom Audio Outputs is the abilityto have a 7.1-channel system in the main listening area at the sametime others are listening to a different source in the remote zone.However, the benefit is achieved at the expense of purchasing anadditional component, i.e., the amplifier.2. Connect the remote speakers directly to the Surround Back/Multiroom Speaker Outputs. See Figure 41.Figure 41 – Surround Back/Multiroom Speaker OutputsIf you do not require a full 7.1-channel system in your main listeningarea, and you prefer not to purchase an external amplifier to powera pair of remote speakers, you may reassign the AVR 347’s surroundback amplifier channels to power the speakers. Your main systemwill be limited to 5.1 channels, which affects your ability to enjoy themany DVDs and other programs recorded in 6.1 and 7.1 channels.AVR347 harman/kardon25
