Referring to drawing of the remote control onpage 11,there is a section of 7 buttons markedC, (AVR 355: 8 Buttons) near the top of theremote designated “Source Selectors”:Cable/Sat, DVD, Media Server, Radio, TV, Gameand AUX. Each of these buttons corresponds toa “source input”. The AVR’s flexible designallows you to use almost any combination ofaudio and video connections for each sourcedevice. The goal of the installation is to matchup each of your source devices, e.g., DVD playerand cable television box, with the correct con-nectors on the AVR.You may connect a source device to any appro-priate input connectors.Note which audio andvideo inputs are used for each device in Table A5in the appendix. Table A1 indicates the defaultinput-connection assignments, any of which maybe changed to match the actual connections inyour system.The precise connections to be made depend onthe capabilities of the source device and yourvideo display (TV). Select the best audio andvideo connections for each source.Analog and Digital Input Connections1. Connect the analog output of a CD player toany of the analog audio 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 analog audio input jacks . Connect theanalog Record/In jacks on the recorder to theaudio output 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*&.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.If your DVD player has HDMI connection, useHDMI connection instead.Although there is no official source on the AVRnamed CD, Phono or Audio, you may assign theaudio device to an available source, such as TV(if the Cable/Sat source is in use for broadcasttelevision), Game or AUX.You can then add the name of the unit to thename of the assigned input, to make it read forexample: "AUX - CD". (Please note that the AVRdoes not have a Phono input with RIAA fordirect hook-up to a record player. You must use aseparate RIAA preamplifier between a recordplayer and the AVR)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 255/AVR 355, as the multiroom system isnot capable 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 355 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. This function is available on theAVR 355 only. The AVR 255 features a STEREOJACK Input instead to which all sorts of portabledevices can be connected via the headphoneoutput of such 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 a cross-sectiongreater than 2 mm2.Cable with a cross-section of 1.5 mm2 may beused for short runs of less than 4 m. We do notrecommend that you use cables with a cross-sec-tion less than 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, be cer-tain 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.Installation and Connections16 INSTALLATION AND CONNECTIONS
