16 INSTALLATION AND CONNECTIONSAfter 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.Audio Equipment ConnectionsWe recommend that you use high-qualityinterconnect cables when making connections tosource equipment and recorders to preserve theintegrity of the signals.When making connections to audio sourceequipment or speakers it is always a goodpractice to unplug the unit from the AC walloutlet. This prevents any possibility ofaccidentally sending audio or transient signals tothe speakers that may damage them.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 acassette deck, MD, CD-R or other audio recorderto the Tape Input jacks . Connect the analogRecord/In jacks on the recorder to the TapeOutput jacks on the AVR.3. 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.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. Connect the front, center and surroundspeaker outputs ' to the respectivespeakers.To ensure 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 greater than2 mm2.Cable with an area of 1.5 mm2 may be used forshort runs of less than 4 m. We do notrecommend that you use cables with an area lessthan 1 mm2 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 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 7. 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, evenif the speakers are a different distance from theAVR.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 beconnected to one or more subwoofer speakers.If you are using a powered subwoofer that doesnot have line-level input connections, follow theinstructions furnished with the speaker forconnection information.9. If an external multi-channel audio source with5.1 or 7.1 outputs such as an external digitalprocessor/decoder, DVD-Audio or SACD player isused, connect the outputs of that device to the8-Channel Direct Inputs .Analog Video EquipmentConnectionsAnalog video equipment is connected in the samemanner as audio components. Again, the use ofhigh-quality interconnect cables is recommendedto preserve signal quality.1. Connect a VCR’s audio and video Play/Outjacks to the Video 1 or Video 2 In jacks !# % on the rear panel. The Audio and VideoRecord/In jacks on the VCR should be connectedto the Video 1 Out jacks & on the AVR.Installation and Connections
