INSTALLATION AND CONNECTIONS 15

After unpacking the unit, and placing it on a solidsurface capable of supporting its weight, you willneed to make the connections to your audio andvideo equipment.

Audio Equipment ConnectionsWe recommend that you use high-quality inter-connect cables when making connections tosource equipment and recorders to preserve theintegrity of the signals.

When making connections to audio sourceequipment or speakers it is always a goodpractice to unplug the unit from the AC walloutlet. This prevents any possibility ofaccidentally sending audio or transient signals tothe speakers that may damage them.

1. Connect the analog output of a CD player to

the CD inputs6.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 Tape Inputjacks2. Connect the analogRecord/In jacks on the recorder to the TapeOutputjacks3 on the AVR 5550.

3. Connect the digital output of any digital

sources 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 InputsUV*.

4. Connect the Coaxial or Optical DigitalOutputsA 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 terminals0.

6. Connect the supplied FM antenna to the FM(75 ohm) connection1. 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 or connec-tion uses 300-ohm twin-lead cable, you should

use a 300-ohm-to-75-ohm adapter to make theconnection.

7. Connect the front, center and surroundspeaker outputsDEFc to the respectivespeakers.

To assure that all the audio signals are carried toyour speakers without loss of clarity or

resolution, we suggest that you use high-qualityspeaker cable. Many brands of cable areavailable and the choice of cable may be influen-ced by the distance between your speakers andthe receiver, the type of speakers you use,personal preferences and other factors. Yourdealer 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 an area greater than2 mm2.

Cable with an area of 1.5 mm2

may be used forshort runs of less than 4 m. We do not recom-mend that you use cables with an area less than1mm2 due to the power loss and degradation inperformance 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

certain to observe proper polarity. Note that thepositive (+) terminal of each speaker connectionnow carries a specific color code as noted onpage 9. 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 this configu-ration.To assure proper phase and optimal per-

formance, consult the identification plate on yourspeaker or the speakers manual to verify polarity.If you do not know the polarity of your speaker,ask your dealer for advice before proceeding, orconsult the speakers manufacturer.

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, evenif the speakers are a different distance from theAVR 5550.

8. Connections to a subwoofer are normallymade via a line level audio connection from theSubwoofer Output4 to the line-level inputof a subwoofer with a built-in amplifier. When apassive subwoofer is used, the connection first

goes to a power amplifier, which will be connect-ed to one or more subwoofer speakers. If you areusing a powered subwoofer that does not haveline-level input connections, follow the instruc-tions furnished with the speaker for connectioninformation.

9. If an external multi-channel audio source with5.1 or 7.1 outputs such as an external digitalprocessor/decoder, DVD-Audio or SACD player isused, connect the outputs of that device to the8-Channel Direct Inputs9.

Video Equipment ConnectionsVideo equipment is connected in the same manneras audio components. Again, the use of high-quality interconnect cables is recommended topreserve signal quality. To ensure best videoperformance S-Video sources should be connect-ed to the AVR 5550 only with their S-Video In/Outputs, not with their composite videoconnectors too.

1. Connect a VCRs audio and video Play/Outjacks to the Video 1 or Video 2 InjacksQTXZ on the rear panel. The Audio and VideoRecord/In jacks on the VCR should be connectedto the Video 1 or Video 2 OutjacksPRWa on the AVR 5550.

2. Connect the analog audio and video outputsof a satellite receiver, cable TV converter or televi-sion set or any other video source to the Video3SY jacks.

3. Connect the analog audio and video outputsof a DVD or laser disc player to the DVDjacks5C .

4. Connect the digital audio outputs of a CD, MDor DVD player, satellite receiver, cable box orHDTV converter to the appropriate Optical orCoaxial Digital InputsUV* .

5. Connect the Composite and S-Video (ifS-Video device is in use) Monitor OutputB

jacks on the receiver to the composite andS-Video input of your television monitor or videoprojector.

6. If your DVD player and monitor both havecomponent video connections, connect the com-ponent outputs of the DVD player to the DVDComponent Video InputsL. Note that evenwhen component video connections are used theaudio connections must still be made to either

the analog DVD Audio Inputs5 or any of theCoaxial or Optical Digital InputjacksUV.

Installation and Connections


16/52

16 INSTALLATION AND CONNECTIONS


SCART A/V Connections

For the connections described above your videodevice needs RCA (cinch) connectors or/and S-Video connectors for all Audio and Video signals:Any normal video device (Not SVHS or High 8)for only playback needs 3 RCA jacks,VCRs forrecord and playback even 6 RCA jacks. AnyS-Video device (SVHS, High 8) needs 2 RCA(Audio) and 1 S-Video jack (Video), if its aplayback unit, or 4 RCA (Audio In/Out) and2 S-Video (Video In/Out) jacks, if its a recordingVCR.

Many european video devices are equipped withRCA (Cinch) or S-Video jacks only partially, notfor all audio and video in/outputs needed asdescribed above, but with a so called Scart orEuro-AV connector (almost rectangular jack with21 pins, see drawings on next page).

In that case the following Scart to Cinchadapters or cables are needed:

Units for playback, such as satellite receivers,camcorders, DVD or LD players, need anadapter from Scart to 3 RCA plugs, see fig. 1(normal video devices) or from Scart to 2RCA+1 S-Video plugs, see fig. 4 (S-Videodevices).

HiFi VCRs need an adapter from Scart to 6RCA plugs, see fig. 2 (normal video), or fromScart to 4 Audio+2S-Video jacks, see fig. 5(S-Video VCR). Read carefully the instruction

attached to the adapter to find which of thesix plugs is used for the record signal to theVCR (connect with the AVRs Out jacks) andfor the playback signal from the VCR (connectwith the AVRs In jacks). Do not misconnectAudio and Video signals. Dont hesitate toconsult your dealer, if you are uncertain.

If you use only normal video devices the TVmonitor needs an adapter from 3 RCA plugsto Scart (fig. 3) only. If also S-Video devices areused an adapter from 2 RCA+1S-Video plugsto Scart is needed additionally (fig. 6),connected to the SCART input on your TV that

is provided for S-Video.Note that only the video plugs (the "yellow"cinch plug in fig. 3 and the S-Video plug infig. 6) must be connected to the TV MonitorOutputB, and the volume on the TV must bereduced to minimum.

Important Note for Adapter Cables:If the cinch connectors of the adapter youll useare labeled, connect the Audio and Video Inplugs with the corresponding Audio and VideoIn jacks on the AVR 5550 (and with a VCR

connect the Out plugs to the Out jacks onthe AVR). Note that with some adapter types itmay be just turned around: If no signal is audi-ble/ visible when the VCR is playing connect theOut plugs to the In jacks on the AVR andturned around. If the adapter plugs are notlabeled in that way, pay attention to the signalflow directions as shown in the diagrams aboveand in the instruction attached to the adapter. Ifuncertain, dont hesitate to consult your dealer.

Important Notes for S-Video connections:1. Only the S-Video In/Out of S-Video devicesmust be connected to the AVR, NOT both,

normal video and S-Video In/Outputs (except theTV, see item below).When both connections are made, only theS-Video signal will be viewed on the screen.

2. Like most common AV units the AVR 5550does not convert the Video signal to S-Video,only vice versa. Thus both connections must bemade from the AVR 5550 to the TV if both,Video and S-Video sources, are used, and theappropriate input on the TV must be selected.

7. If another component video device is available,connect it to the Video 2 Component VideoInputjacksJ. The audio connections for thisdevice should be made to either the Video 2InputjacksX or any of the Coaxial or Optical

Digital InputjacksUV.8. If the component video inputs are used,connect the Component Video OutputK tothe component video inputs of your TV, projectoror display device.

9. If you have a camcorder, video game or otheraudio/video device that is connected to the AVRon a temporary, rather than permanent basis,connect the audio, video and digital audio out-puts of that device to the Front Panel Inputs*. A device connected to the Video 4

jacks is selected as the Video 4 input, andconnected to the digital jacks* it is selected

as "Optical 3" or "Coaxial 3" input. (See page21 for more information on input configuration.)

or Composite video signals may only be viewedin their native formats and will not be convert-ed to the other formats. S-Video signals will beconverted to composite signal.The OSD can beviewed on the TV screen in any case, with Videoor S-Video input selected on the TV.

When the component video jacks are used, theon-screen menus will not be visible. You mustswitch to the standard composite or S-Videoinput on your TV to view those menus.

All component inputs/outputs can be used forRGB signals too, in the same way as describedfor the Y/Pr/Pb signals, then connected to the

jacks with the corresponding color.But this is only correct as long as only the threeRGB video signals are output by the videosource, with a sync signal in the "G" signalonly, without any sync signal output separatelyby the source.

Important Note for the Use ofSCART-Cinch Adapters:When video sources are connected to the TVdirectly with a SCART cable, specific controlsignals apart from Audio/Video signals will be

fed to the TV. These specific signals are:With allvideo sources, the signal for automatic inputselection that switches the TV automatically tothe appropriate input as soon as the videosource is started. And with DVD players, thesignals automatically turning the TV to 4:3/16:9format (with 16:9 TVs or with 4:3 TVs withselectable 16:9 format) and turning the RGBvideo decoder of the TV on or off, depending onthe DVD players setting. With any adapter cable,these control signals will be lost and theappropriate setting of the TV must be mademanually.

Note for RGB signal with SCART:If you use a unit providing RGB signals on aSCART output (as e.g. most DVD players do) andyou want to use that RGB signal, this SCARToutput must be connected directly to your TV.Although the AVR 5550 RDS can switch three-way video signals (like component signalsY/Pb/Pr), most TVs need separate sync signalsfor RGB (also with SCART) that cannot beswitched and provided by the AVR 5550.RGB signals can be pathed throughthe AVR 5550 only when no separate syncsignal is needed (see last Video ConnectionNoteon page 16).

18 INSTALLATION AND CONNECTIONS

System and Power Connections

The AVR 5550 is designed for flexible use withmultiroom systems, external control componentsand power amplifiers.

Main Room Remote Control ExtensionIf the receiver is placed behind a solid or smokedglass cabinet door, the obstruction may preventthe remote sensor from receiving commands. Inthis event, the remote sensor of any HarmanKardon or other compatible device, not coveredby the door, or an optional remote sensor maybe used. Connect the Remote IR Output ofthat device or the output of the remote sensor tothe Remote IR InputjackN.

If other components are also prevented fromreceiving remote commands, only one sensor isneeded. Simply use this units sensor or a remote

eye by running a connection from the RemoteIR OutputjackM to the Remote IR Input

jack on Harman Kardon or other compatibleequipment.

Multiroom IR LinkThe key to remote room operation is to link theremote room to the AVR 5550s location withwire for an infrared receiver and speakers or anamplifier.The remote room IR receiver (this can bean optional IR receiver or any other remotableHarman Kardon device in the remote room withIR sensor integrated) should be connected to theAVR 5550 via standard coaxial cable. Connect the

Remote IR Output of the device or of theoptional sensor with the Multiroom IR Input

jackO on the AVR 5550s rear panel.

If other Harman Kardon compatible sourceequipment is part of the main room installation,the Remote IR OutputjackM on the rearpanel should be connected to the IR IN jack onthat source device. This will enable the remoteroom location to control source equipmentfunctions.

NOTE: All remotely controlled components mustbe linked together in a daisy chain. Connectthe IR OUTjack of one unit to the IR IN of the

next to establish this chain.

Multiroom Audio ConnectionsDepending on your system`s requirement anddistance from the AVR 5550 to the remoteroom, three options are available for audioconnection:

Option 1: Use high-quality, shielded audiointerconnect phono cable from the AVR 5550slocation to the remote room. In the remoteroom, connect the interconnect cable to a stereopower amplifier. The amplifier will be connectedto the rooms speakers.At the AVR 5550, plug

the audio interconnect cables into theMultiroom Output Jacks7 on the AVR5550s rear panel.

Option 2: Place the amplifier that will providepower to the remote location speakers in thesame room as the AVR 5550, and connect theMultiroom Outputjacks7 on the rear panelof the AVR to the audio input of the remote

room amplifier. Use the appropriate speaker wireto connect the optional power amplifier to theremote speakers. High-quality wire of at least2.5 mm2 is recommended for long multiroomconnections.

Option 3: Taking advantage of the AVR 5550sbuilt-in seven-channel amplifier, it is possible touse two of the amplifier channels to powerspeakers in the remote room.When using thisoption you will not be able to use the full7.1-channel capabilities of the AVR 5550 in themain listening room, but you will be able to addanother listening room without additional

external power amplifiers.To use the internalamplifiers to power a remote zone, connect thespeakers for the remote room location to theSurround Back/Multiroom SpeakerOutputsc. Before using the remote room youwill need to configure the amplifiers forsurround operation by changing a setting inthe Advanced Select menu, following theinstructions shown on page 37.

NOTE: For all options, you may connect anoptional IR sensor (Harman Kardon He1000) inthe remote room to the AVR 5550 via an appro-priate cable. Connect the sensors cable to the

Multiroom IR InputO on the AVR 5550 anduse the Zone II remote to control the room vol-ume.Alternatively, you may install an optionalvolume control between the output of the ampli-fiers and the speakers.

A-BUS Installation ConnectionsThe AVR 5550 is among the very few receiversavailable today that offers built-in A-BUS Ready

operation.When used with an optional A-BUSkeypad or control module, you have all thebenefits of remote zone operation without theneed for an external power amplifier.

To use the AVR 5550 with an approved A-BUS

product, simply connect the keypad or modulethat is in the remote room to the AVR 5550using standard Category 5 wiring that isproperly rated for the inwall use specific to theinstallation.Terminate the wiring at the receiverend to a standard RJ-45 jack in compliance withthe instructions furnished with the A-BUSmodule.

No further installation or adjustment is needed,as the A-BUS connector on the AVR 5550 routesthe signals in and out of the keypad to theirproper destination for power, signal source andcontrol. The output fed to the A-BUS jack is

determined by the AVR 5550s multiroomsystem, and the menus may be used as is.

RS-232 ConnectionsThe AVR 5550 includes an RS-232 serial portconnection that may be used to control the unitvia compatible optional, external keypads orcontrol systems.The physical connection to the

AVR 5550 from the control device is a standardD-9 connection, but to assure compatible andproper operation, specific software commandsand pin wiring schemes are required. Due to thecomplexity of RS-232 connections werecommend that they be made only by trainedinstallers familiar with their use.To obtainadditional information on the use of theAVR 5550 with RS-232 control, please contactHarman Kardons customer service departmentor consult our Web site atwww.harmankardon.com.

AC Power Connections

This unit is equipped with two accessory ACoutlets.They may be used to power accessorydevices, but they should not be used withhigh-current draw equipment such as poweramplifiers.The total power draw to theUnswitched OutletH must not exceed100 watts, that to the Switched OutletG50 watts.

The SwitchedG outlet will receive power onlywhen the unit is on completely. This is recom-mended for devices that have no power switchor a mechanical power switch that may be left inthe ON position.

NOTE: Many audio and video products go into aStandby mode when they are used withswitched outlets, and cannot be fully turned onusing the outlet alone without a remote controlcommand.

The UnswitchedH outlet will receive poweras long as the unit is plugged into a powered ACoutlet and the Main Power Switch1 is on.

The AVR 5550 features a removable power cordthat allows wires to be run to a complex instal-lation so that the unit, itself, need not beinstalled until it is ready for connection. When all

connections described above have been made,connect the AC Power cord to the AC PowerCord JackI.

The AVR 5550 draws significantly more currentthan other household devices such as computersthat use removable power cords. For that rea-son, it is important that only the cord suppliedwith the unit (or a direct replacement of identi-cal capacity) be used.

Once the power cord is connected, you arealmost ready to enjoy the AVR 5550s incrediblepower and fidelity!

Speaker Selection

No matter which type or brand of speakers isused, the same model or brand of speakershould be used for the front-left, center andfront-right speakers. This creates a seamlessfront soundstage and eliminates the possibilityof distracting sonic disturbances that occur whena sound moves across mismatched front-channelspeakers.

Speaker Placement

The placement of speakers in a multichannelhome-theater system can have a noticeableimpact on the quality of sound reproduced.

Depending on the type of center-channelspeaker in use and your viewing device, placethe center speaker either directly above or below

your TV, or in the center behind a perforatedfront-projection screen.

Once the center-channel speaker is installed,position the left-front and right-front speakers sothat they are as far away from one another asthe center-channel speaker is from the preferredlistening position. Ideally, the front-channelspeakers should be placed so that their tweetersare no more than 60cm above or below thetweeter in the center-channel speaker.

They should also be at least 0.5 meter from yourTV set unless the speakers are magneticallyshielded to avoid colourings on the TV screen.

Note that most speakers are not shielded, evenwith complete surround sets only the Centerspeaker may be.

Depending on the specifics of your roomacoustics and the type of speakers in use, youmay find that imaging is improved by moving thefront-left and front-right speakers slightlyforward of the center-channel speaker. If

possible, adjust all front loudspeakers so thatthey are aimed at ear height when you areseated in the listening position.

Using these guidelines, youll find that it takessome experimentation to find the correctlocation for the front speakers in your particularinstallation. Dont be afraid to move thingsaround until the system sounds correct. Optimizeyour speakers so that audio transitions acrossthe front of the room sound smooth.

When the AVR 5550 is used in 5.1-channel oper-ation, the preferred location for surround speak-ers is on the side walls of the room, at or slightly

behind the listening position. In a 7.1-channelsystem, both side surround and back surroundspeakers are required.The center of the speakershould face you (see below).

Rear surround speakers are required when a full7.1-channel system is installed, and they mayalso be used in 5.1 channel mode as an alterna-tive mounting position when it is not practical toplace the main surround speakers at the sides ofthe room. Speakers may be placed on a rearwall, behind the listening position.As with theside speakers, the center of the rear surroundsshould face you.The speakers should be no more

than 2 meters behind the rear of the seatingarea.

Subwoofers produce largely nondirectionalsound, so they may be placed almost anywherein a room. Actual placement should be based onroom size and shape and the type of subwooferused. One method of finding the optimallocation for a subwoofer is to begin by placing itin the front of the room, about 15cm from awall, or near the front corner of the room.Another method is to temporarily place thesubwoofer in the spot where you will normallysit, and then walk around the room until you

find a spot where the subwoofer sounds best.Place the subwoofer in that spot. You shouldalso follow the instructions of the subwoofersmanufacturer, or you may wish to experimentwith the best location for a subwoofer in yourlistening room.

20 SYSTEM CONFIGURATION

System Configuration

Once the speakers have been placed in the roomand connected, the remaining steps are to pro-gram the system configuration memories. Withthe AVR 5550 two kind of memories are used,those associated individually with the input

selected, e.g. surround modes, and others work-ing globally for all inputs selected like speakeroutput levels, crossover frequencies or delaytimes used by the surround sound processor.

First Turn On

You are now ready to power up the AVR 5550 tobegin these final adjustments.

1. Make certain that the AC power cord is firmlyinserted in to the AC Power cord RecepticleI and plug the cord into an unswitched ACoutlet. To maintian the unit's safety rating,DO NOT substitute the power cord for one with

lower current capacity.

2. Press the Main Power Switch1 in until itlatches and the word OFF on the top of theswitch disappears inside the front panel. Notethat the Power Indicator3 will turnorange, indicating that the unit is in theStandby mode.

3. Remove the protective plastic film from themain front-panel lens. If left in place, the filmmay affect the performance of your remotecontrol.

4. Install the three supplied AAA batteries in the

remote as shown. Be certain to follow the (+)and () polarity indicators that are on the topof the battery compartment.

5. Turn the AVR 5550 on either by pressing theSystem Power Control2 or the Input

Source Selector% on the front panel, or viathe remote by pressing the Power On Button3, AVR Selector5 or any of the InputSelectors46 on the remote.The PowerIndicator3 will turn green to confirm thatthe unit is on, and the Main InformationDisplay will also light up.

NOTE: After pressing one of the Input Selectorbuttons4 to turn the unit on, press the AVRSelector5 to have the remote control the AVRfunctions.

Using the On-Screen Display

When making the following adjustments, you mayfind them easier to make via the units on-screendisplay system. These easy-to-read displays giveyou a clear picture of the current status of theunit and facilitate speaker, delay, input or digitalselection you are making.

To view the on-screen displays, make certain youhave made a connection from the VideoMonitor OutjackB on the rear panel to thecomposite or S-Video input of your TV or projec-tor. In order to view the AVRs displays, the correctvideo input must be selected on your video dis-play. Note that the on-screen menus are notavailable when a component video display is inuse.

IMPORTANT NOTE: When viewing the on-screen

menus using a CRT-based projector, plasma displayor any direct-view CRT monitor or television, it isimportant that they not be left on the screen for anextended period of time.As with any video display,but particularly with projectors, constant display ofa static image such as these menus or video gameimages may cause the image to be permanentlyburned into the CRT.This type of damage is notcovered by the AVR 5550 warranty and may not becovered by the projector TV sets warranty.

The AVR 5550 has two on-screen display modes,Semi-OSD and Full-OSD. When making con-figuration adjustments, it is recommended that

the Full-OSD mode be used. This will place a com-plete status report or option listing on the screen,making it easier to view the available options andmake the settings on the screen.The Semi-OSDmode uses one-line displays only.
