Rear Panel Connections¡ CD Input: Connect the output ofyour CD player or D/A converter tothese jacks.™ TV Input: Connect the audiooutputs of a TV, satellite receiver orany audio source to these jacks.£ Tape 2 Input: Connect thePLAY/OUT jacks of an audio taperecorder to these jacks.¢ Tape 2 Output: Connect theRECORD/INPUT jacks of an audiotape recorder to these jacks.∞ Tape 1 Monitor Input: Connectthe PLAY/OUT jacks of an audiotape recorder to these jacks.§ Tape 1 Monitor Output: Connectthe RECORD/INPUT jacks of anaudio tape recorder to these jacks.NOTE: The recorder connected tothe Tape 1/Mon jacks may be moni-tored during a recording session bypressing the Tape 1/Mon button8d on the front panel or remote.¶ Video 2 A/V Inputs: Connect theaudio and video PLAY/OUT jacks ofa VCR, DVD, LV, Satellite system orother video source to these jacks.• Video 1 A/V Inputs: Connect theaudio and video PLAY/OUT jacks ofyour main VCR to these jacks.ª Video 1 A/V Outputs: Connectthe audio and video REC/IN jacks ofyour main VCR to these jacks.NOTE: The Video 1 jacks may beused for any video source, but whenused with a VCR they will permitdubbing from one source to anotherwhile a separate source is beinglistened to by selecting the VCRDubbing switch ˘ 34.‚ Video Monitor Output: Connectthis jack to the video input of a TV orvideo projector to view the selectedsource.⁄ Rear Speaker Outputs: Connectthese terminals to the input terminalson your rear/surround speakers.IMPORTANT NOTE: A speaker mustbe connected to both of these out-puts in order for the unit to functionproperly. If only one speaker is con-nected there will be no rear channeloutput.¤ Front Right Speaker: Connectthe front right channel speaker tothese terminals.‹ Front Left Speaker: Connect thefront left channel speaker to theseterminals.› Center Speaker: Connect thecenter channel speaker to theseterminals.fi Unswitched Accessory ACPower Outlet: This outlet providesAC power that may be used for anyAC device up to 100 watts. Thepower will remain on at this outletregardless of whether the AVR40 ison or off.fl Switched Accessory AC PowerOutlets: These outlets provide ACpower only when the AVR40 isturned on. Note that the total currentdraw of the products may notexceed 100 watts.‡ AC Power Cord: Connect thisplug to an unswitched, wall mountedAC outlet.° Remote Control ExtensionOutput: This jack may be connect-ed to other compatible HarmanKardon products so that they willreceive infrared commands cap-tured by the AVR40’s remote sensor.· Remote Control ExtensionInput: If the AVR40’s front panel IRsensor is blocked due to cabinetdoors or other obstructions, anexternal IR sensor may be used.Connect the output of the sensor tothis jack.a Subwoofer Outputs: Connectthese jacks to the line level input of apowered subwoofer, or to the inputsof a subwoofer amplifier.NOTE: This output is a full rangeleft/right signal. For proper operationBOTH jacks must be connected tothe left/right inputs of a poweredsubwoofer, or a “Y” cable must beused to connect the two outputstogether if a single input mono sub-woofer is used.WARNING: Since this is a full rangeoutput, the signal must be sentthrough a crossover or low pass filterbefore being used with a passivesubwoofer or other speaker thatdoes not contain a built in crossover.b Front Preamp Outputs: Thesejacks provide the output for the frontleft and right channels to an ampli-fier. In normal operation, unless anexternal power amplifier is used, thejumper pins should remain connect-ed to the Front Main In jacks c.c Main In: These jacks are theinput to the AVR40’s front left/rightchannel power amplifier. Unless anexternal power amplifier is used forthe left/right channels, the jumperpins should remain connected tothe Front Pre Out jacks b.d Rear (Surround) Outputs:These jacks may be used to connectthe rear/surround channels to anexternal power amplifier or to theinputs of the AVR40’s main left/rightchannel amplifier.e Center Preamp Outputs: Thesejacks may be used to connect thecenter channel output to an externalpower amplifier.NOTE: In most applications only onecenter channel connection will berequired. The output of both jacks isidentical, and either jack may beused for system connections.f AM Antenna Input: Connect theAM loop antenna supplied with theAVR40 to these terminals. An exter-nal AM antenna may also be con-nected here.g FM Antenna Input: Connect anFM antenna to these terminals. Notethat a 300 ohm to 75 ohm adapter isrequired for connections from twinlead dipole antennas.8
