Plug the AC line cord of theappliance directly into a 120V AC 60Hz outlet and turn theAC power switch on. Any current measured must not exceedo.5mA.ANY MEASUREMENTS NOT WITHIN THE LIMITSOUTLINED ABOVE ARE INDICATIVE OF APOTENTIAL SHOCK HAZARD AND MUST BECORRECTED BEFORE RETURNING THE APPLIANCETO THE CUSTOMER.DeviceundertestTest allexposed metalsurfacesAlso test withplug reversed(Using AC adapterplug as required)AC Leakage TestLeakagecurrenttesterReading shouldnot be above0.5mAEarthgroundFRONT PANEL CONTROLS 5?Main Power Switch: Press this button toapply power to the AVR.When the switch ispressed in, the unit is placed in a Standbymode, as indicated by the orange LED 2.Thisbutton MUST be pressed in to operate the unit.To turn the unit off completely and prevent theuse of the remote control, this switch should bepressed until it pops out from the front panelso that the word “OFF” may be read at the topof the switch.NOTE:This switch is normally left in the “ON”position.1System Power Control:When the MainPower Switch?is “ON,” press this button toturn on the AVR; press it again to turn the unitoff (to Standby). Note that the PowerIndicator2will turn blue when the unit is on.2Power Indicator:This LED will be illumi-nated in orange when the unit is in the Standbymode to signal that the unit is ready to beturned on.When the unit is in operation, theindicator will turn blue.3Headphone Jack:This jack may be used tolisten to the AVRs output through a pair ofheadphones. Be certain that the headphoneshave a standard 6.3 mm stereo phone plug.Note that the speakers will automatically beturned off when the headphones are connected.4Digital Optical 3 Input: Connect the opti-cal digital audio output of an audio or video prod-uct to this jack.When the Input is not in use,becertain to keep the plastic cap installed to avoiddust contamination that might degrade future performance.5Speaker/Channel Input Indicators:Theseindicators are multipurpose,indicating either thespeaker type selected for each channel or theincoming data-signal configuration.The left,cen-ter,right,right surround and left surround speakerindicators are composed of three boxes,while thesubwoofer is a single box.The center box lightswhen a “Small”speaker is selected,and the twoouter boxes light when “Large”speakers areselected.When none of the boxes are lit for thecenter,surround or subwoofer channels,nospeaker has been selected for that position.(Seepage 16 for more information on configuringspeakers.) The letters inside each of the centerboxes display active input channels.For standardanalog inputs,only the L and R will light,indicat-ing a stereo input.When a digital source is play-ing,the indicators will light to display the chan-nels begin received at the digital input.When theletters flash,the digital input has been interrupt-ed.(See page 20 for more information on theChannel Indicators).Front Panel Controls?123 4 56 7 8 9A B C D E F G H I J Main Power SwitchSystem Power ControlPower IndicatorHeadphone JackDigital Optical 3 InputSpeaker/Channel Input IndicatorSurround Mode Group SelectorTuningTuner Band SelectorPreset Stations SelectorInput Source SelectorRDS Select ButtonSurround Mode SelectorSurround Mode IndicatorsRemote Sensor WindowMain Information DisplayDigital Coax 3 InputVideo 3 input jacksVolume ControlInput Indicators167G9DFIJC8BL24A5E3DIGITALLOGIC 7VID 1DVDCDFMAMTAPEVID 2VID 3PRO LOGIC 3 STEREO DSP5 CH.

Each press of the button willselect a major mode grouping in the followingorder:Dolby Modes DTS Digital Modes DSPModes Stereo Modes Logic 7 ModesOnce the button is pressed so that the name ofthe desired surround mode group appears in theLower Display LineF, press the SurroundMode SelectorCto cycle through the indi-vidual modes available. For example, press thisbutton to select Dolby modes, and then pressthe Surround Mode SelectorCto choosefrom the various mode options.7Tuning Selector: Press the left side of thebutton to tune lower frequency stations and theright side of the button to tune higher frequencystations.When a station with a strong signal isreached,MANUAL TUNEDor AUTOTUNEDwill appear in the Main InformationDisplay F(see page 27 for more informationon tuning stations).8Tuner Band Selector: Pressing this buttonwill automatically switch the AVR to the Tunermode. Pressing it again will switch between theAM and FM frequency bands, holding it pressedfor some seconds will switch between stereoand mono receiving and between automatic andmanual tuning mode (See page 27 for moreinformation on the tuner).9Preset Stations Selector: Press thisbutton to scroll up or down through the list ofstations that have been entered into the presetmemory. (See page 27 for more information ontuner programming.)AInput Source Selector: Press this buttonto change the input by scrolling through the listof input sources.BRDS Select Button: Press this button todisplay the various messages that are part of theRDS data system of the AVRs tuner.(See page 28for more information on RDS).CSurround Mode Selector: Press this but-ton to select from among the available surroundmode options for the mode group selected.Thespecific modes will vary based on the number ofspeakers available, the mode group and if theinput source is digital or analog. For example,press the Surround Mode Group Selector6to select a mode grouping such as Dolby orLogic 7, and then press this button to see themode choices available. For more information onmode selection, see page 21.DSurround Mode Indicators: Indicator willilluminate in front of the surround mode that iscurrently in use.ERemote Sensor Window:The sensorbehind this window receives infrared signalsfrom the remote control.Aim the remote at thisarea and do not block or cover it unless anexternal remote sensor is installed.FMain Information Display:This displaydelivers messages and status indications to helpyou operate the receiver.GDigital Coax 3 Input:This jack is normallyused for connection to the output of portabledigital audio devices, video game consoles orother products that have a coax digital jack.HVideo 3 Input Jacks: These audio/videojacks may be used for temporary connection tovideo games or portable audio/video productssuch as camcorders and portable audio players.IVolume Control:Turn this knob clockwiseto increase the volume, counterclockwise todecrease the volume. If the AVR is muted,adjusting volume control will automaticallyrelease the unit from the silenced condition.JInput indicators: Indicator will illuminatein front of the input that is currently being usedas the source for the AVR.29782_AVR132_ENG_sort 10/08/06 16:45 Side 6REAR PANEL CONNECTIONS 7Rear Panel Connectionsc?fideb fla?Tape InputsTape OutputsVideo 1 Audio InputsAM AntennaVideo 1 Audio OutputsDVD Audio InputsFM AntennaCD InputsVideo 2 Component Video InputsCoaxial Digital InputsSubwoofer OutputVideo Monitor OutputsFront/Center Speaker OutputsSurround Speaker OutputsComponent Video OutputsVideo 1 Component Video InputsAC Power CordDVD Video InputsVideo 1 Video OutputsVideo 2 Audio InputsVideo 2 Video InputsOptical Digital InputsVideo 1 Video Inputs6-Channel Direct Inputs ?Tape Inputs: Connect these jacks to thePLAY/OUT jacks of an audio recorder.?Tape Outputs: Connect these jacks to theRECORD/INPUT jacks of an audio recorder.?Video 1 Audio Inputs: Connect these jacksto the PLAY/OUT audio jacks on a VCR or othervideo source.?AMAntenna:ConnecttheAMloopantennasuppliedwiththereceivertotheseterminals.IfanexternalAMantennaisused,makeconnections tothe AM and GND terminals in accordance withthe instructions supplied with the antenna.?Video 1 Audio Outputs: Connect thesejacks to the RECORD/INPUT audio jacks on a VCR or any other Audio recorder.?DVD Audio Inputs: Connect these jacks tothe analog audio jacks on a DVD or other videosource.?FM Antenna: Connect the supplied indoor oran optional external FM antenna to this terminal.?CD Inputs: Connect these jacks to the ana-log output of a compact disc player or CDchanger.?Video 2 Component Video Inputs:Connect the Y/Pr/Pb component video outputs ofan HDTV Set-top convertor, satellite receiver, orother video source device with component videooutputs to these jacks.?Coaxial Digital Inputs: Connect the coaxdigital output from a DVD player,HDTV receiver,LD player,MD player or CD player to these jacks.The signal may be either a Dolby Digital signal,DTS signal or a standard PCM digital source.Donot connect the RF digital output of an LD play-er to these jacks.?Subwoofer Output: Connect this jack tothe line-level input of a powered subwoofer.
