System InstallationAfter unpacking the unit, and placing it on a solidsurface capable of supporting its weight, you willneed to make the connections to your audio andvideo equipment.IMPORTANT NOTE: For your personal safetyand to avoid possible damage to your equipmentand speakers, it is always good practice to turnoff and unplug the AVR and ALL source equip-ment from the AC output before making anyaudio or video system connections.Audio Equipment ConnectionsWe recommend that you use high-quality inter-connect cables when making connections tosource equipment and recorders to preserve theintegrity of the signals.1. Connect the analog output of a CD player tothe CD Inputs ¶.NOTE: When the CD player has both fixed andvariable audio outputs, it is best to use the fixedoutput unless you find that the input to thereceiver is so low that the sound is noisy, or sohigh that the signal is distorted.2. Connect the analog Play/Out jacks of a cas-sette deck, MD, CD-R or other audio recorder tothe Tape Input Jacks £. Connect the analogRecord/In jacks on the recorder to the TapeOutput Jacks ¢ on the AVR 320.3. Connect the output of any digital sourcessuch as such as a CD or DVD changer or play-er, advanced video game, a digital satellitereceiver, HDTV tuner or digital cable set-topbox or the output of a compatible computersound card to the Optical and CoaxialDigital Inputs *Ó.4. Connect the coaxial or optical Digital AudioOutputs ⁄ on the rear panel of the AVR 320 tothe matching digital input connections on a CD-Ror MiniDisc recorder.5. Assemble the AM Loop Antenna suppliedwith the unit as shown below. Connect it to theAM and GND Screw Terminals ¡ .6. Connect the supplied FM antenna to the FM(75-ohm) Connection ™. The FM antennamay be an external roof antenna, an insidepowered or wire-lead antenna or a connectionfrom a cable TV system. Note that if the anten-na or connection uses 300-ohm twin-leadcable, you must use the 300-ohm-to-75-ohmadapter supplied with the unit to make the con-nection.7. Connect the front, center and surroundspeaker outputs › fi fl to the respectivespeakers.To ensure that all the audio signals are carriedto your speakers without loss of clarity or reso-lution, we suggest that you use high-qualityspeaker cable. Many brands of cable are avail-able and the choice of cable may be influencedby the distance between your speakers and thereceiver, the type of speakers you use, personalpreferences and other factors. Your dealer orinstaller is a valuable resource to consult inselecting the proper cable.Regardless of the brand of cable selected, werecommend that you use a cable constructed ofmultistrand copper with a gauge of 14 or smaller.Remember that in specifying cable, the lowerthe number, the thicker the cable.Cable with a gauge of 16 may be used for shortruns of less than ten feet. We do not recom-mend that you use cables with an AWG equiva-lent of 18 or higher, due to the power loss anddegradation in performance that will occur.Cables that are run inside walls should have theappropriate markings to indicate listing with UL,CSA or other appropriate testing agency stan-dards. Questions about running cables insidewalls should be referred to your installer or alicensed electrician who is familiar with the NECand/or the applicable local building codes inyour area.When connecting wires to the speakers, be cer-tain to observe proper polarity. Note that thepositive (+) terminal of each speaker connectionnow carries a specific color code as noted onpage 11. 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 this config-uration. To ensure proper phase and optimalperformance, consult the identification plate onyour speaker or the speaker’s manual to verifypolarity. If you do not know the polarity of yourspeaker, ask your dealer for advice before pro-ceeding, or consult the speaker’s manufacturer.We also recommend that the length of cableused to connect speaker pairs be identical. Forexample, use the same length piece of cableto connect the front-left and front-right orsurround-left and surround-right speakers,even if the speakers are a different distancefrom the AVR 320.8. 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.9. If an external multi-channel audio sourcewith 5.1 outputs such as an external digitalprocessor/decoder, DVD-Audio or SACD playeris used, connect the outputs of that device tothe 6-Channel Direct Inputs ª.10. If an external multi-channel audio sourcewith 7.1 outputs such as an external digitalprocessor/decoder, DVD-Audio or SACD playeris used, first connect the outputs of that deviceto both the 6 Channel Direct Inputs as notedabove, and then connect the Surround Back Leftand Surround Back Right output channels ofthe source device to the 8-Channel DirectInputs ‚.11. If a 7.1 channel source device is connectedas noted in the item above, you must use anoptional audio power amplifier for those chan-nels. Connect the SBL and SBR PreampOutputs to the inputs of the amplifierfeeding those channels' speakers.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.1. Connect a VCR’s or other video source’saudio and video Play/Out jacks to the Video 1or Video 2 In Jacks hk on the rearpanel. The Audio and Video Record/In jacks onthe VCR should be connected to the Video 1or Video 2 Out Jacks gi on theAVR 320.2.
