18 INSTALLATION AND CONNECTIONS3. Connect the digital output of any digitalsources such as a CD or DVD changer or player,advanced video game, a digital satellite receiver,HDTV tuner or digital cable set-top box or theoutput of a compatible computer sound card tothe Optical and Coaxial Digital Inputs*Ó.We recommend connecting the coaxial digitalaudio output of your DVD player to the Coax 1Digital Audio Input , since that digital inputis assigned to the DVD source by default.The Video 2/Cable/Sat source defaults to theOptical 1 Digital Audio Input . If yourcable television set-top box or satellite receiveris equipped with an optical digital audio output,we recommend that you connect it to this inputto obtain the benefits of higher-quality digitalaudio (such as PCM, Dolby Digital 2.0 or DolbyDigital 5.1 signals when broadcast by your cableor satellite provider).NOTE: If you wish for your digital source deviceto be available for use by the multiroom system,you will need to connect its analog audiooutputs to the appropriate inputs on theAVR 347, as the multiroom system is notcapable of distributing digital signals to theremote zone.4. Connect the Coaxial or Optical DigitalOutputs on the rear panel of the AVR to thematching digital input connections on a CD-R orMiniDisc recorder.5. Assemble the AM Loop Antenna supplied withthe unit as shown below. Connect it to the AMand GND screw terminals .6. Connect the supplied FM antenna to the FM(75 ohm) connection . The FM antenna maybe an external roof antenna, an inside poweredor wire lead antenna or a connection from acable system. Note that if the antenna orconnection uses 300-ohm twin-lead cable, youshould use a 300-ohm-to-75-ohm adapter tomake the connection.7. With the AVR 347 turned off, connect theoptional Harman Kardon toDigital Media Player (DMP) Connector .Your compatible Apple® iPod® may be docked inwhen you wish to use it as your audiosource device.8. Connect the front, center and surroundspeaker outputs to the respectivespeakers.To assure that all the audio signals are carried toyour speakers without loss of clarity orresolution, we suggest that you use high-qualityspeaker cable. Many brands of cable areavailable and the choice of cable may beinfluenced by the distance between yourspeakers and the receiver, the type of speakersyou use, personal preferences and other factors.Your dealer or installer is a valuable resource toconsult in selecting the proper cable.Regardless of the brand of cable selected, werecommend that you use a cable constructed offine, multistrand copper with an area greaterthan 2 mm2.Cable with an area of 1.5 mm2 may be used forshort runs of less than 4 m. We do not recom-mend that you use cables with an area less than1mm2 due to the power loss and degradation inperformance that will occur.Cables that are run inside walls should have theappropriate markings to indicate listing with anyappropriate testing agency standards. Questionsabout running cables inside walls should bereferred to your installer or a licensed electricianwho is familiar with the applicable local buildingcodes in your area.When connecting wires to the speakers, becertain to observe proper polarity. Note that thepositive (+) terminal of each speaker connectionnow carries a specific color code as noted onpage 8. However, most speakers will still use ared terminal for the postive (+) connection.Connect the “negative” or “black” wire to thesame terminal on both the receiver and thespeaker.NOTE: While most speaker manufacturersadhere to an industry convention of using blackterminals for negative and red ones for positive,some manufacturers may vary from thisconfiguration. To assure proper phase andoptimal performance, consult the identificationplate on your speaker or the speaker’s manual toverify polarity. If you do not know the polarity ofyour speaker, ask your dealer for advice beforeproceeding, or consult the speaker’smanufacturer.We also recommend that the length of cableused to connect speaker pairs be identical. Forexample, use the same length piece of cable toconnect the front-left and front-right orsurround-left and surround-right speakers,even if the speakers are a different distancefrom the AVR.9. Connections to a subwoofer are normallymade via a line level audio connection from theSubwoofer Output to the line-level inputof a subwoofer with a built-in amplifier. When apassive subwoofer is used, the connection firstgoes to a power amplifier, which will be con-nected to one or more subwoofer speakers. Ifyou are using a powered subwoofer that doesnot have line-level input connections, follow theinstructions furnished with the speaker for con-nection information.10. If an external multi-channel audio sourcewith 5.1 outputs such as an external digitalprocessor/decoder, DVD-Audio, SACD, Blu-ray orHD-DVD player is used, connect the outputs ofthat device to the 8-Channel Direct Inputs .Video Equipment ConnectionsVideo equipment is connected in the same man-ner as audio components. Again, the use of high-quality interconnect cables is recommended topreserve signal quality. To ensure best video per-formance S-Video sources should be connectedto the AVR only with their S-Video In/Outputs,not with their composite video connectors too.If you have already connected a source device toone of the HDMI inputs as explained in theAudio Equipment section, then you have auto-matically made a video connection at the sametime, as the HDMI signal includes both digitalaudio and video components.If your video display or source device is notHDMI-capable, you will need to use one of theanalog video connections (composite, S- or com-ponent video), if available, as described below.If the source device is not capable of transmit-ting its digital audio signal through the HDMIconnection, then use one of the coaxial or opti-cal digital audio inputs for the source.If a multichannel analog audio connection isrequired for certain lossless formats (e.g. DVD-Audio, SACD, HD-DVD or Blu-ray Disc), you maymake both connections. To listen to the multi-channel disc, first select the HDMI source input,then select the 6-/8-channel analog audioinputs, and the AVR will retain the last videosource you selected.Installation and Connections
