Installation and SetupWhen 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 AVR75and speaker.Note: While most speaker manufacturersadhere to an industry convention of usingblack terminals for negative and red onesfor positive, some manufacturers mayvary from this configuration. To assureproper phase, and optimal performance,consult the identification plate on yourspeaker, or the speaker’s manual to verifypolarity. If you do not know the polarityof your speaker, ask your dealer for advicebefore proceeding, or consult thespeaker’s manufacturer.7. Connections to a subwoofer are madevia a line level audio connection fromthe Subwoofer Output ⁄ to the linelevel input of a subwoofer with a built-inamplifier. If a passive subwoofer is used,the connection first goes to a poweramplifier, which will be connected to oneor more subwoofer speakers.Video Input and Output ConnectionsVideo connections are made in a similarfashion to those for audio components.Again, the use of high-quality intercon-nect cables is recommended to preservesignal quality.1. Connect the VCR’s audio, video andS-Video OUT jacks to the Video In jacksd i on the rear panel. The audio, videoand S-Video IN jacks on the VCR shouldbe connected to the Video Out jackse h on the AVR75.2. Connect the audio and video outputsof a satellite receiver, cable TV converteror television set or any other video sourceto the TV jacks ª.3. Connect the audio, video and S-Videooutputs of a DVD or laser disc player tothe DVD jacks •.4. Connect the TV Mon f g jacks onthe receiver to the video, or S-Videoinputs, of your television monitor orvideo projector.5. As the AVR75 does not mix or changebetween standard composite video andS-Video signals, both monitor connec-tions must be made if you use bothsignal systems.Note: The on-screen menus are visibleon the composite video output only.System and Power ConnectionsThe AVR75 is designed for flexible usewith external control components andpower amplifiers. These connections areeasy to make during an initial installa-tion, or at a later date should you chooseto upgrade your system.Remote Control ExtensionIf the receiver is placed behind a solid orsmoked glass cabinet door, the obstruc-tion may prevent the remote sensor fromreceiving commands. In this event, anoptional remote sensor may be used.Connect the output of the remote sensorto the Remote Cont. In jack b.If other components are also preventedfrom receiving remote commands, onlyone sensor is needed. They may use thisunit’s sensor or a remote eye by runninga connection from the Remote Cont.Out jack c to the Remote In jack onHarman Kardon or other compatibleequipment.External Audio PowerAmplifier ConnectionsIf desired, optional external power audiopower amplifiers may be used with theAVR75. Connections to these amplifiersare made by using audio interconnectcables connected to both the PreampOutputs ‚ on the rear panel andthe audio input jacks of the externalamplifiers.AC Power ConnectionsThis unit is equipped with two accessoryAC outlets. They may be used to poweraccessory devices, but they should not beused with high-current draw equipmentsuch as power amplifiers. The total powerdraw may not exceed 50w to each outlet.The Switched fi outlet will receivepower only when the unit is on. This isrecommended for devices that have nopower switch, or a mechanical powerswitch that may be left in the “ON”position.Note: Devices with electronic powerswitches may only go into a Standbymode when plugged in here.The Unswitched fl outlet will receivepower as long as the unit is plugged intoa powered AC outlet.Finally, when all connections are com-plete, plug the power cord into a non-switched 120-volt AC wall outlet.
