12 INSTALLATION AND CONNECTIONSINSTALLATION AND CONNECTIONSSystem InstallationAfter unpacking the unit, locating it in a place with ade-quate ventilation and placing it on a solid surface capableof supporting its weight, you will need to make the con-nections to your audio and video equipment.IMPORTANT NOTE: For your personal safety and toavoid possible damage to your equipment and speakers,it is always a good practice to turn off and unplug theAVR and ALL source equipment from the AC outputbefore making any audio or video system connections.Audio Equipment ConnectionsWe recommend that you use high-quality interconnectcables when making connections to source equipmentand recorders to preserve the integrity of the signals.1. Connect the analog outputs of a CD player to theCD Audio Inputs ™.NOTE: When the CD player has both fixed and vari-able audio outputs, it is best to use the fixed outputunless you find that the input to the receiver is so lowthat the sound is noisy, or so high that it is distorted.2. Connect the analog Play/Out jacks of a cassettedeck, MD, CD-R or other audio recorder to the TapeInput Jacks ¢. Connect the analog Record/In jackson the recorder to the Tape Output Jacks £ on theAVR 140.3. Connect the output of any digital sources such asa CD or DVD changer or player, advanced videogame, a digital satellite receiver, HDTV tuner or digitalcable set-top box or the output of a compatiblecomputer sound card to the Optical and CoaxialDigital Audio Inputs ·d*(. We recommendconnecting the coaxial digital audio output of yourDVD player to the Coax 1 Digital Audio Input ·,since that digital input is assigned to the DVD sourceby default.4. Connect the Coaxial or Optical Digital AudioOutputs fl‡ on the rear panel of the AVR 140 to thematching digital input connections on a CD-R or MiniDiscor other digital recorder.5. Assemble the AM Loop Antenna supplied with theunit so that the tabs at the bottom of the antenna loopsnap into the holes in the base. Connect it to the AMAntenna Terminals V.6. Connect the supplied FM antenna to the FM (75-ohm) Connection ¡. The FM antenna may be anexternal roof antenna, an inside powered or wire-leadantenna or a connection from a cable TV system. Ifthe antenna or connection uses 300-ohm twin-leadcable, you must use the 300-ohm-to-75-ohm adaptersupplied with the unit to make the connection.7. With the AVR 140 turned off, connect the optionalHarman Kardon to Digital MediaPlayer (DMP) Connector b. Your compatibleApple® iPod® may be docked in when youwish to use it as your audio source device. Videomaterials stored on the iPod are not able to be viewedusing the AVR.8. Connect the front, center, surround and surroundback speaker outputs §¶•ª to the respectivespeakers.To ensure that all the audio signals are carried to yourspeakers without loss of clarity or resolution, we sug-gest that you use high-quality speaker cable. Manybrands of cable are available and the choice of cablemay be influenced by the distance between yourspeakers and the receiver, the type of speakers youuse, personal preferences and other factors. Your dealeror installer is a valuable resource to consult in select-ing the proper cable.Regardless of the brand of cable selected, we recom-mend that you use a cable constructed of multistrandcopper with a gauge of 14 or smaller. Remember thatin specifying cable, the lower the number, the thickerthe cable.Cable with a gauge of 16 may be used for short runsof less than 10 feet. We do not recommend that youuse cables with an AWG equivalent of 18 or higher,due to the power loss and degradation in performancethat will occur.Cables that are run inside walls should have the appro-priate markings to indicate listing with UL, CSA or otherappropriate testing agency standards. Questions aboutrunning cables inside walls should be referred to yourinstaller or a licensed electrician who is familiar withthe NEC and/or the applicable local building codes inyour area.When connecting wires to the speakers, observeproper polarity. Note that the positive (+) terminal ofeach speaker connection may carry a specific colorcode, as noted on page 7. However, many speakersstill use a red terminal for the positive (+) connection.Connect the “negative” or “black” wire to the same ter-minal on both the receiver and the speaker.NOTE: While most speaker manufacturers adhere toan industry convention of using black terminals fornegative and red ones for positive, some may varyfrom this configuration. To ensure proper phase andoptimal performance, consult the identification plate onyour speaker or the speaker’s manual to verify polarity.If you do not know the polarity of your speaker, askyour dealer for advice before proceeding, or consultthe speaker’s manufacturer.We also recommend that the length of cable usedto connect speaker pairs be identical. For example,use the same length piece of cable to connect thefront-left and front-right or surround-left and sur-round-right speakers, even if the speakers are adifferent distance from the AVR 140.Note that it is not possible to use the AVR 140 in a7.1-channel configuration. Any source informationthat the AVR receives or derives for the surroundback left and right channels, e.g. through the 6/8-Channel Direct Inputs g or during 7-channelStereo processing, is combined and outputtedto the single-channel Surround Back SpeakerOutputs ¶.9. Connections to a subwoofer are normally made viaa line-level audio connection from the SubwooferOutput ∞ to the line-level input of a subwoofer witha built-in amplifier. When a passive subwoofer is used,the connection first goes to a power amplifier, whichwill be connected to one or more subwoofers. If youare using a powered subwoofer that does not haveline-level input connections, follow the instructions fur-nished with the speaker for connection information.10. If an external multichannel audio source with 5.1,6.1, 7.1 outputs such as an external digital proces-sor/decoder, DVD-Audio or SACD player is used, con-nect the outputs of that device to the 6/8-ChannelDirect Inputs g.Video Equipment ConnectionsVideo equipment is connected in the same manner asaudio components. The use of high-quality interconnectcables is recommended to preserve signal quality.1. Connect a VCR’s, DVD recorder’s, personal videorecorder’s or other video source’s audio and videoPlay/Out jacks to the Video 1 Audio/Video and/orS-Video Input Jacks LS on the rear panel. TheAudio and Video Record/In jacks on the recordershould be connected to the Video 1 Audio/Videoand/or S-Video Output Jacks NT on the AVR 140.Although any video device may be connected to thesejacks, we recommend connecting your video recorderso that you may take advantage of the fact that theremote control is preprogrammed with video recorderproduct codes for the Video 1 device.2. Connect the analog audio and video outputs of asatellite receiver, cable TV converter, television set orany other video source to the Video 2 Audio/VideoThe BridgeTMThe BridgeTMThe BridgeTMAVR140 harman/kardon13
