Installation and ConnectionsSystem InstallationAfter unpacking the unit, and placing iton a solid surface capable of supportingits weight, you will need to make theconnections to your audio and videoequipment. These steps need to be doneonly when the receiver is first installed,or when a change is made to the inputsource equipment.Audio Equipment ConnectionsWe recommend that you use high-qualityinterconnect cables when making connec-tions to source equipment and recordersto preserve the quality of the signals.When making connections to audiosource equipment or speakers it is alwaysa good practice to unplug the unit fromthe AC wall outlet. This prevents any pos-sibility of accidentally sending audio ortransient signals to the speakers that maydamage them.1. Connect the analog output of a CDplayer to the CD inputs §.NOTE: When the CD player has bothfixed and variable audio outputs it is bestto use the fixed output unless you findthat the input to the receiver is so lowthat the sound is noisy, or high that thesignal is distorted.2. Connect the Play/Out jacks of a cas-sette deck, MD or other audio recorder tothe Tape Monitor In jacks c. Connectthe Record/In jacks on the recorder tothe Tape Monitor Out jacks d onthe AVR45.3. Connect the output of any digitalsources to be used to the appropriateconnections on the AVR45 rear panel.Note that the Optical and Coaxialdigital inputs · ° may be used witheither a Dolby Digital (AC-3) sourceor the output of a conventional CD orLV player’s PCM (SP/DIF) output.4. Assemble the AM Loop Antenna sup-plied with the unit as shown below.Connect it to the AM and GND screwterminals ¡.5. Connect an FM antenna to theFM (75 ohm) connection ™. TheFM antenna may be an external roofantenna, an inside powered or wire leadantenna or a connection from a cableTV system. Note that if the antenna orconnection uses 300-ohm twin-leadcable, you must use the 300-ohm-to-75-ohm adapter supplied with the unitto make the connection.6. Connect the front, center andsurround speaker outputs ‚ ⁄ lto the respective speakers.To assure that all the audio signals arecarried to your speakers without loss ofclarity or resolution, we suggest that youuse high-quality speaker cable. Manybrands of cable are available, and thechoice of cable may be influenced by thedistance between your speakers and thisreceiver, the type of speakers you use,personal preferences and other factors.Your dealer or installer is a valuableresource to consult in selecting theproper cable.Regardless of the brand of cable selected,we recommend that you use a cable con-structed of fine, multistrand copper with agauge of 14 or smaller. Remember that inspecifying cable, the lower the number,the thicker the cable.Cable with a gauge of 16 may be used forshort runs of less than ten feet. We do notrecommend that you use cables with anAWG equivalent of 18 or higher due tothe power loss and degradation inperformance that will occur.Cables that are run inside walls shouldhave the appropriate markings to indicatelisting with UL, CSA or other appropriatetesting agency standards. Questions aboutrunning cables inside walls should bereferred to your installer or a licensedelectrical contractor who is familiar withthe NEC and/or the applicable localbuilding codes in your area.When connecting wires to the speakers,be certain to observe proper polarity.Remember to connect the “negative” or“black” wire to the same terminal on thereceiver and the speaker. Similarly, the“positive” or “red” wire should be con-nected to the like terminal on the AVR45and speaker.We also recommend that the length ofcable used to connect speaker pairs beidentical. For example, use the samelength piece of cable to connect the frontleft and front right or surround left andsurround right speakers, even if thespeakers are a different distance fromthe AVR45.14
