Installation and Connections

System InstallationAfter unpacking the unit, and placing iton a solid surface capable of supportingits weight, you will need to make theconnections to your audio and videoequipment. These steps need to be doneonly when the receiver is first installed,or when a change is made to the inputsource equipment.

Audio Equipment ConnectionsWe recommend that you use high-qualityinterconnect cables when making connec-tions to source equipment and recordersto preserve the quality of the signals.

When making connections to audiosource equipment or speakers it is alwaysa good practice to unplug the unit fromthe AC wall outlet. This prevents any pos-sibility of accidentally sending audio ortransient signals to the speakers that maydamage them.

1. Connect the analog output of a CDplayer to the CD inputs .

NOTE: When the CD player has bothfixed and variable audio outputs it is bestto use the fixed output unless you findthat the input to the receiver is so lowthat the sound is noisy, or high that thesignal is distorted.

2. Connect the Play/Out jacks of a cas-sette deck, MD or other audio recorder tothe Tape Monitor In jacks c. Connectthe Record/In jacks on the recorder tothe Tape Monitor Out jacks d on the AVR45.

3. Connect the output of any digitalsources to be used to the appropriateconnections on the AVR45 rear panel.Note that the Optical and Coaxialdigital inputs may be used witheither a Dolby Digital (AC-3) source or the output of a conventional CD or LV players PCM (SP/DIF) output.

4. Assemble the AM Loop Antenna sup-plied with the unit as shown below.Connect it to the AM and GND screwterminals `.

5. Connect an FM antenna to the FM (75 ohm) connection . The FM antenna may be an external roofantenna, an inside powered or wire leadantenna or a connection from a cable TV system. Note that if the antenna orconnection uses 300-ohm twin-leadcable, you must use the 300-ohm-to-75-ohm adapter supplied with the unit to make the connection.

6. Connect the front, center andsurround speaker outputs lto the respective speakers.

To assure that all the audio signals arecarried to your speakers without loss ofclarity or resolution, we suggest that youuse high-quality speaker cable. Manybrands of cable are available, and thechoice of cable may be influenced by thedistance between your speakers and thisreceiver, the type of speakers you use,personal preferences and other factors.

Your dealer or installer is a valuableresource to consult in selecting theproper cable.

Regardless of the brand of cable selected,we recommend that you use a cable con-structed of fine, multistrand copper with agauge of 14 or smaller. Remember that inspecifying cable, the lower the number,the thicker the cable.

Cable with a gauge of 16 may be used forshort runs of less than ten feet. We do notrecommend that you use cables with anAWG equivalent of 18 or higher due tothe power loss and degradation inperformance that will occur.

Cables that are run inside walls shouldhave the appropriate markings to indicatelisting with UL, CSA or other appropriatetesting agency standards. Questions aboutrunning cables inside walls should bereferred to your installer or a licensedelectrical contractor who is familiar withthe NEC and/or the applicable localbuilding codes in your area.

When connecting wires to the speakers,be certain to observe proper polarity.Remember to connect the negative orblack wire to the same terminal on thereceiver and the speaker. Similarly, thepositive or red wire should be con-nected to the like terminal on the AVR45and speaker.

We also recommend that the length ofcable used to connect speaker pairs beidentical. For example, use the samelength piece of cable to connect the frontleft and front right or surround left andsurround right speakers, even if thespeakers are a different distance fromthe AVR45.

14



Installation and Connections

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 speakers manual to verifypolarity. If you do not know the polarity of your speaker, ask your dealer for advice before proceeding, or consult the speakers 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 Equipment ConnectionsVideo equipment is connected in a fashionsimilar to audio components. Again, theuse of high-quality interconnect cables isrecommended to preserve signal quality.

1. Connect a VCRs audio and videoPlay/Out jacks to the Video 1 In jacks on the rear panel. The audio andRecord/In jacks on the VCR should beconnected to the Video 1 Out jacks on the AVR45.

2. Connect the audio and video outputsof a satellite receiver, cable TV converteror television set or any other video sourceto the Video 2 In jacks .

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

4. Connect the TV Monitor Out jacks on the receiver to the video input of your television monitor or video projector.

System and Power Connections

The AVR45 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 a.

If other components are also preventedfrom receiving remote commands, onlyone sensor is needed. They may use thisunits sensor or a remote eye by runninga connection from the Remote Cont.Out jack b to the Remote In jack onHarman Kardon or other compatibleequipment.

External Audio Power AmplifierConnectionsIf desired, optional external power audiopower amplifiers may be used with theAVR45. Connections to these amplifiersare made by using audio interconnectcables connected to both the PreampOutputs on the rear panel and the audio input jacks of the externalamplifiers.

External Audio Decoder ConnectionTo provide for the ultimate flexibility, the AVR45 may be used in conjunctionwith optional, external decoders fordigital audio systems other than theAVR45s own built-in Dolby Digitalsystem. If an external decoder is used,connect the output jacks of the decoderto the 6-Channel Direct inputs ,making sure to match channels.

These jacks may also be used for connec-tions to devices usch as DVD players orHigh Definition Television (HDTV) sets ordecoders that feature built-in digital sur-round decoders. Although the digitaldecoding system in the AVR45 will typicallyprovide audio performance that is superiorto other decoders, you may use these jacksto provide an additional 6-channel inputfor connection to a DVD player or HDTV set with a built-in decoder and discrete 6-channel analog outputs.

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 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 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. Yourealmost ready to enjoy the AVR45!

System Configuration

When all audio, video and system con-nections have been made, there are a fewconfiguration adjustments to be made. Afew minutes spent to correctly configureand calibrate the unit will greatly add toyour listening experience.

Speaker Selection and PlacementThe placement of speakers in a multi-channel-home-theater system can have a noticeable impact on the quality ofsound reproduced.

No matter which type or brand of speakersis used, the same model or brand ofspeaker should be used for the front left,center and right speakers. This creates aseamless front soundstage, and elimi-nates the possibility of distracting sonicdisturbances that occur when a soundmoves across mismatched front channelspeakers.

Speaker PlacementDepending on the type of center channelspeaker in use and your viewing device,place the center speaker directly above orbelow your TV or in the center behind aperforated front projection screen.

Once the center channel speaker isinstalled, position the left and right front speakers so that they are as faraway from one another as the centerchannel speaker is from the preferredlistening position. Ideally, the frontchannel speakers should be placed sothat their tweeters are no more than 24"off center from the tweeter in the centerchannel speaker.

Depending on the specifics of your roomacoustics and the type of speakers in use,you may find that imaging is improvedby moving the front left and right speak-ers slightly forward of the center channel

speaker. If possible, adjust all front loudspeakers so that they are aimed atear height when you are seated in the listening position.

Using these guidelines, youll find that ittakes some experimentation to find thecorrect location for the front speakers inyour particular installation. Dont beafraid to move things around until thesystem sounds correct. Optimize yourspeakers so that pans across the front ofthe room sound smooth, and that soundsfrom all speakers appear to arrive at thelistening position at the same time with-out delay from the center speaker asopposed to the left and right speakers.

Surround speakers should be placed onthe side walls of the room, at or slightlybehind the listening position. The centerof the speaker should face into the room.The speakers should be located so thatthe bottom of the cabinet is at least twofeet higher than the listeners ears whenseated in the desired area.

If side wall mounting is not practical, thespeakers may be placed on a rear wall,behind the listening position. Again, theyshould be located so that the bottom ofthe cabinet is at least two feet higherthan the listeners ears. The speakersshould be no more than six feet behindthe rear of the seating area.

Subwoofers produce non-directionalsound, so they may be placed almostanywhere in a room. Subwoofer place-ment is highly influenced by room sizeand shape, and the type of subwooferused. Follow the instructions of the sub-woofers manufacturer, or experimentwith the best location for a subwoofer inyour listening room.

System Configuration17

System SetupOnce the speakers have been placed in theroom and connected, the final step in thesetup process is to enter the settings thatconfigure the AVR45s bass managementsystem for the type of speakers used inyour system, the calibration of the outputlevels and the delay times used by the sur-round sound processor. Before proceedingfurther, this is a good time to review theinstallation section of the manual tomake certain that all connections areproperly made.

You are now ready to power up the AVR45to begin these final adjustments.

1. Plug the Power Cable to anunswitched AC outlet.

2. Press the Main Power Switch 1in so that it latches in with the OFFwording on the top of the switchinside the front panel. Note that thePower Indicator 3 will turnamber, indicating that the unit is inthe Standby mode.

3. Install the four supplied AAA batteriesin the remote as shown. Be certain toobserve the (+) and () polarityindicators shown in the bottom of thebattery compartment.

4. Turn the AVR45 on either by pressingthe System Power Control 3onthe front panel, or via the remote byfirst pressing the AVR Selector a,and then pressing the Power buttonc. The Power Indicator 3 willturn green to confirm that the unit ison, and the Information Display will also light up.

Speaker ConfigurationThe first few adjustments tell the AVR45,which type of speakers are in use. This isimportant as it adjusts the settings thatdetermine which speakers receive low-frequency (bass) information. For eachof these settings use the LARGE setting ifthe speakers for a particular position aretraditional full-range loudspeakers thatare capable of reproducing sounds below 100Hz. Use the SMALL setting forsmaller, frequency-limited satellitespeakers that do not reproduce soundsbelow 100Hz. Note that when smallspeakers are used, a subwoofer isrequired to reproduce low-frequencysounds. Remember that the large andsmall descriptions do not refer to theactual physical size of the speakers, buttheir ability to reproduce low-frequencysounds. If you are in doubt as to whichcategory describes your speakers, consultthe specifications in the speakers ownersmanual, or ask your dealer.

With the AVR45 turned on, follow thesesteps to configure the speakers:

1. Put the AVR45 in the Dolby Pro Logicmode by pressing the Dolby ProLogic Selector on the frontpanel or by pressing the SurroundMode Selector yon the remote,followed by the / buttons guntil PRO LOGIC appears in theMain Information Display S andthe PRO LOGIC indicator F lights.

2. Press the Speaker button x onthe remote or front panel. The wordsFRNT SPEAKERwill appear in theMain Information Display S .

3. Press the Set button i.

4. Press the / buttons g on theremote or the Selector buttonson the front panel until eitherLARGE or SMALL appears to matchthe type of speakers you have at theleft front and right front positions, asdescribed by the definitions shownbelow.

When SMALL is selected, low-frequency sounds will be sent to thesubwoofer output only. Note that ifyou choose this option, and there isno subwoofer connected, you willnot hear any low-frequency soundsfrom the front channels.




When LARGE is selected, a full-range output will be sent to thefront left and right outputs, and NO low-frequency signals will besent to the subwoofer output.

5. When you have completed yourselection for the front channel, pressthe Set button i, and thenpress the / buttons g on theremote or the Selector buttonson the front panel to change the dis-play to CEN SPEAKER.

6. Press the Set button i again,and use the / buttons g on the remote, or the Selector buttons on the front panel, to select theoption that best describes your systembased on the speaker definitionsshown above.

When CEN SP SMALL is selected, low-frequency centerchannel sounds will be sent to thesubwoofer output only. Note that ifyou choose this option and there isno subwoofer connected, you willnot hear any low-frequency soundsfrom the center channel speaker.

When CEN SP LARGE is selected, a full-range output will besent to the center speaker output,and NO center channel signal willbe sent to the subwoofer output.

When CEN SP NONE is selected,no signals will be sent to the centerchannel output. The receiver willoperate in a phantom centerchannel mode and center channelinformation will be sent to the leftand right front channel outputs.

7. When you have completed yourselection for the center channel, pressthe Set button i, and thenpress the / buttons g on theremote or the Selector buttonson the front panel to change thedisplay to SUR SPEAKER.

8. Press the Set button i again,and then use the / buttons gon the remote or the Selectorbuttons on the front panel toselect the option that best describesyour system based on the speakerdefinitions shown above.

When SUR SP SMALL is selected, low-frequency surroundchannel sounds will be sent to thesubwoofer output only. Note that ifyou choose this option and there isno subwoofer connected, you willnot hear any low-frequency soundsfrom the surround speaker.

When SUR SP LARGE is selected,a full-range output will be sent to thesurround channel outputs, and NOsurround channel signals will be sentto the subwoofer output.

When SUR SP NONE is selected,surround sound information will besplit between the front left and frontright outputs. Note that for optimalperformance when no surroundspeakers are in use, the Dolby 3 Stereo mode should be used instead of Dolby Pro Logic.

9. When you have completed yourselection for the surround channel,press the Set button i, and then press the / buttons g on the remote or the Selector buttonson the front panel to change the displayto SW SPEAKER.

10. Press the Set button i, and then press the / buttons g on the remote or the Selector buttonson the front panel to select the optionthat best describes your system.

Select S-W SP ON if a subwoofer is connected to your system.

Select S-W SP OFF if a subwoofer isNOT connected to your system. Notethat when no subwoofer is selected,low-frequency sounds below 100Hzwill be sent to the front left/rightspeakers, provided that the selection in step 4, above, has been set toLARGE. Otherwise, no low-frequencysounds will be heard. This option isnot available when the front, center orsurround speakers are set to SMALL.




11. When all speaker selections havebeen made, press the Set button i to return to normal operation.

Output Level AdjustmentOutput level adjustment is a key part ofthe configuration process for any sur-round sound product. It is particularlyimportant for a Dolby Digital receiversuch as the AVR45, as correct outputs willensure that you hear sound tracks in theirproper place with the proper intensity.

IMPORTANT NOTE: Many listenersare often confused about the operationof the surround channels. While someassume that sound should always becoming from each speaker, most of thetime there will be little or no sound inthe surround channels. This is becausethey are only used when a movie directoror sound mixer specifically places soundthere to create ambiance, an effect or tocontinue action from the front of theroom to the rear. When the output levelsare properly set it is normal for rear/surround speakers to operate onlyoccasionally. Artificially increasing thevolume to the rear speakers may destroythe illusion of an enveloping sound fieldthat duplicates the way you hear soundin a movie theater or concert hall.

Before beginning the adjustment processmake certain that all speaker connectionshave been properly made. The systemvolume should be set to the level that you will use during a typical listeningsession. Finally, make certain that theBalance Control 7 is set to the center12 oclock position.

To adjust and calibrate the output levels,follow these steps. For accurate calibration,it is a good idea to make these adjustmentsfrom the location in your room that isyour favorite listening position:

1. Put the AVR45 in the Dolby Pro Logicmode by pressing the Dolby ProLogic Selector on the frontpanel or by pressing the SurroundMode Selector yon the remote,followed by the / buttons guntil PRO LOGIC appears in theMain Information Display S andthe PRO LOGIC indicator F lights.

2. Press the Test Tone button eon the remote or front panel. Thewords T -T FL 0dBwill appearin the Main Information DisplayS , and the letters FLwill flash onceeach second.

3. At this point, the test noise will beginto circulate among all the speakers ina clockwise rotation.

NOTE: This is a good time to verifythat the speakers have been properlyconnected. As the test noise circulates,listen to make certain that the soundcomes from the speaker positionshown in the Main InformationDisplay. If the sound from a speakerlocation does NOT match the positionindicated in the display, turn theAVR45 off and check the speakerwiring to make certain that eachspeaker is connected to the correctoutput terminal.

4. After checking for speaker placement,let the test noise circulate again, andlisten to see which channels soundlouder than the others. Using thefront left (FL in the display) speakeras a reference, press the / buttonsg on the remote or the Selectorbuttons on the front panel oneach channel to begin to bring themto the same level. Note that when oneof the buttons is pushed, the test noisecirculation will pause on the channelbeing adjusted to give you time tomake the adjustment. When yourelease the button, the circulationwill resume.

5. Continue to adjust the individualspeakers until they all have the samevolume. Note that adjustmentsshould be made with the /buttons g on the remote or theSelector buttons on the frontpanel only, NOT the main volumecontrols. Then press the Set buttoni to memorize the change. Ifyou are using a sound pressure (SPL)meter for precise level adjustment, setthe volume so that the meter reads75dB, C-Weighting Slow.

NOTE: The subwoofer output level is notadjustable using the test tone. To changethe subwoofer level, follow the steps forOutput Level Trim Adjustment on page27.

6. When you have adjusted the outputsso that all channels have the samelevel, press the Test Tone button e on the remote or front panelto complete the adjustment.




Delay SettingsOne aspect of the surround modes is thedelay of audio signals between the frontspeakers and the rear speakers. Eachsurround mode is factory preset with aspecific delay time, but it is possible toindividually adjust the delay timing tocustom tailor the sound to your individ-ual taste and the acoustic conditions inyour listening room or home theater.

The factory setting is appropriate formost rooms, but some installationscreate an uncommon distance betweenthe front and surround speakers that maycause the arrival of front channel soundsto become disconnected from surroundchannel sounds.

To resynchronize the front and surroundchannels, follow these steps:

1. Measure the distance from thelistening/viewing position to thefront speakers.

2. Measure the distance from thelistening/viewing position to thesurround speakers.

3. Subtract the distance to the surroundspeakers from the distance to thefront speakers.

a. When setting the delay time for theDolby Digital surround mode, theoptimal delay time is the resultingfigure. For example, if the frontspeakers are ten feet away and thesurround speakers are five feetaway, the optimal delay time isfigured as 105=5. Thus, in thisexample, the delay should be set atfive milliseconds.

b. When setting the delay time for the Pro Logic mode, take the resultof the subtraction and add 15 toobtain the optimal delay time. Forexample, if the front speakers areten feet away and the surroundspeakers are five feet away, theoptimal delay time is figured as 105+15=20. Thus, in thisexample, the delay should be set at twenty milliseconds.

The Dolby Digital mode also provides aseparate setting for the center channeldelay mode, since the discrete nature of Dolby Digital signals makes thelocation of the center channel speakermore critical. To calculate the delay forthe center channel, measure the distancefrom the preferred listening position inthe center of the room to both the centerchannel speaker and either the left orright speaker.

NOTE: The Theater, Hall 1 and Hall 2modes use a fixed, non-adjustable delay time.

If the distances are equal no furtheradjustment is required and the centerdelay should be set to zero. If the distanceto the front speakers is greater than thedistance to the center speaker you maywish to reposition the speakers by movingthe front left/right speakers closer to thelistening position or the center speakerfurther away from the listening position.

If repositioning of the speakers is notpossible, adjust the center delay time sothat you add one millisecond of centerchannel delay for each foot that thedistance to the center speaker lagsbehind the front speakers. For example,if the front left/right speakers are each 10 feet from the listening position andthe center channel speaker is 8 feet away, the delay is figured as 108=2,suggesting an optimal center delay of 2 milliseconds.

To set the delay times, follow these steps:

1. Put the AVR45 in the Dolby Pro Logicmode by pressing the Dolby ProLogic Selector on the frontpanel, or by pressing the SurroundMode Selector yon the remote,followed by the / buttons guntil PRO LOGIC appears in theMain Information Display S andthe PRO LOGIC indicator F lights.

2. Press the Delay button v on the remote or front panel. The words S DELAY TIMEwill appear in theMain Information Display S .

20





4. Adjust the delay time by pressing the / buttons g on the remote orthe Selector buttons on the frontpanel until the delay time figure cal-culated using the formula enteredabove appears in the display.

5. If no adjustment is needed for the center channel delay, press theSet button i to enter thesetting into the AVR45s memory. If the calculations outlined above for the center channel delay requirean adjustment, proceed with thefollowing steps:

6. Select a digital input by pressing the Digital button w. Press the / buttons g on the remoteor the Selector buttons on thefront panel until either COAX orOPTICAL appear in the MainInformation Display S . Note thatfor this adjustment, either input maybe selected.


8. Select the Dolby Digital mode eitherby pressing the front panel DolbyDigital Selector( or by pressingthe Surround Mode Selector yon the remote, and then pressing the / buttons g on the remoteuntil DOLBY AC-3 appears in theMain Information Display S .Ignore any NO DATA messagethat may appear.

9. Press the Delay button v onthe remote or front panel. The wordsS DELAY TIME appears in theMain Information Display S .

10. Press the / buttons g on theremote once, so that C DELAYTIME appears in the MainInformation Display S .


12. Press the / buttons g on the remote until the desired delaytime for the center channel appearsin the display.

13. Press the Set button i to enterthe setting into the AVR45s memory.

Congratulations! You have now completedthe setup, adjustment and calibration ofthe AVR45. You are now ready to enjoy thefinest in music and home theater listening.

When using the AVR45 for the firsttime, it is necessary to press the MainPower button 1 on the front panel toturn the unit on. This places the unit in astandby mode, as indicated by the ambercolor of the Power Indicator 3 . Oncethe unit is in standby, you may begin alistening session by pressing the SystemPower Control 2 on the front panel orthe Power button c on the remote.Note that the Power Indicator 3 willturn green. This will turn the unit on andreturn it to the input source that was lastused. The unit may also be turned onfrom standby by pressing any of theSource Selector buttons on the remotek or front panel 9)!@#$.

To turn the unit off at the end of a listen-ing session simply press the SystemPower Control 2 on the front panelor the Power button c on the remote.Power to any equipment plugged into the rear panel Switched AC Outlet will be shut off and the PowerIndicator 3 will turn amber.

When the remote is used to turn the unitoff it is actually placing the system in astandby mode, as indicated by the ambercolor of the Power Indicator 3.

When you will be away from home for an extended period of time it is always a good idea to completely turn the

unit off using the front panel MainPower Switch 1. Note that all presetmemories are lost if the unit is leftturned off with the Main PowerSwitch 1 for more than two weeks.

Source Selection

To select a source at any time, pressany of the Source Selector buttons onthe remote k or front panel 9)!@#$.

The front panel Video 3 Inputs 8may be used to connect a device such asa video game or camcorder to your homeentertainment system on a temporarybasis.

When an audio source is selected thelast video input used remains routed tothe Video Outputs 1 and TVMonitor Output . This permitssimultaneous viewing and listening todifferent sources.

During a listening session you maywish to adjust the Bass 5 and Treble6 controls to suit your listening tastes.

Adjust the volume to a comfortablelevel using the front panel VolumeControl or remote VolumeUp/Down z buttons.

To temporarily silence all speakeroutputs press the Mute button d . This will cut the output to all speakers,but it will not effect any recording ordubbing that may be in progress. Whenthe system is muted the MUTE indicatorA will light in the InformationDisplay . Press the Mute button d again to return to normal operation.

For private listening, plug the 1/4"stereo phone plug from a pair of stereoheadphones into the front panelHeadphone jack 4.

When a Video Input source is selectedthe video signal for that input will berouted to the TV Monitor Video Outputjack and will be viewable on a TV mon-itor connected to the AVR45. Make certainthat your TV is set to the proper input toview the signal.

To program the AVR45 for automaticturn off, press the Sleep button onthe remote. Each press of the button willincrease the time before shut down in thefollowing sequence:

The sleep time will be displayed in theInformation Display and it will countdown until the time has elapsed.

When the programmed time has elapsedthe unit will automatically turn off. Notethat the front panel display will dim toone half brightness when the Sleep func-tion is programmed. To cancel the Sleepfunction, press the Sleep button until the information display returns tonormal brightness and the Sleepindicator numbers disappear.

Surround Mode Selection

One of the most important features of the AVR45 is its ability to reproduce a fullmultichannel surround sound field fromDolby Digital sources, analog matrix surround encoded programs and stan-dard stereo programs. In all a total ofseven listening modes are available onthe AVR45.

Operation

Selection of a surround mode is based onpersonal taste, as well as the type of pro-gram source material being used. Forexample, motion pictures or TV programsbearing the logo of one of the major sur-round encoding processes, such as DolbySurround, DTS Stereo or UltraStereomay be played in either the Dolby Digital,Dolby Pro Logic or Movie Surrounddepending on the source material.

FEATURES

This mode is available only when the source material is encoded with Dolby Digital(AC-3) data. It provides up to five separate main audio channels and a special dedi-cated Low-Frequency Effects channel.

Dolby Pro Logic is the standard mode for analog surround sound decoding. It uses information encoded in a two-channel stereo recording to produce four distinct channels: Left, Center, Right and Surround. Use this mode for accurate reproductionof programs bearing the Dolby Surround, DTS Stereo, UltraStereo or otherSurround logos. Surround encoded programs include videocassette, DVD and LDmovies, TV and cable programs, radio programs and audio CDs. Dolby Pro Logic processing may also be used to provide a pleasing surround effect with some stereophonic source material that does not carry surround encoding.

Dolby 3 Stereo uses the information contained in a surround encoded or two-channelstereo program to create center channel information. In addition, the informationthat is normally sent to the rear channel surround speakers is carefully mixed in withthe front left and right channels for increased realism. Use this mode when you have acenter channel speaker, but no surround speakers.

Theater Surround processing uses matrix surround decoding to simulate a standardmovie or stage theater.

These modes are designed for use with stereo recordings. They provide a sound-fieldeffect that simulates the complex combination of direct and reflected sounds that create the rich reverberant atmosphere of a medium-sized concert hall (Hall 1) or alarger concert hall (Hall 2).

This mode turns off all surround processing and presents the pure left and right channel presentation of two channel stereo programs.

Surround Mode Chart

NOTE: Once a program has beenencoded with surround information, itretains the surround matrix as long asthe program is broadcast in stereo. Thus,movies with surround sound will carrysurround information when they arebroadcast via conventional TV stations,cable, pay TV and satellite transmission.In addition, a growing number of made-for-television programs, sports broad-casts, radio dramas and music CDs arealso recorded in surround sound. You

may obtain a list of these programs anddiscs from the Dolby Laboratories website at www.dolby.com

When a program is not listed as carryingintentional surround information, youmay find that Pro Logic or Dolby 3-Stereomodes often deliver enveloping surroundpresentations through the use of thenatural information present in all stereorecordings. However, for stereo, but non-surround programs, we suggest that youtry the Hall 1, Hall 2 or Theater modes.



Operation

Surround modes are selected using eitherthe front panel controls or the remote. Toselect a surround mode from the frontpanel, simply press the button that corre-sponds to the desired mode (. To select a surround mode using theremote, press the Surround ModeSelector y, and then press the /buttons g to change the mode. As you press the buttons, the surround mode name will appear in the MainInformation Display S, and anindividulal mode indicator will also light up D /F /J.

Note that the Dolby Digital Mode mayonly be selected when a Dolby Digitalsource is playing. For more informationon Dolby Digital, see the following sectionof this manual.

To listen to a program in traditional two-channel stereo, using the front left andfront right speakers only (plus the sub-woofer if installed and configured), pressthe Surround Off button on thefront panel, or follow the insturctionsshown above for using the remote untilSURR OFF appears in the MainInformation Display S. When theAVR45s surround circuits are turned off,and it is in the Stereo mode, the BYPASSindicator B will illuminate in theInformation Display .

Digital Audio Playback

Dolby DigitalDolby Digital (also known as AC-3) is thelatest advancement in surround-soundtechnology, delivering up to five full-range surround channels (left, center,right, left surround and right surround)plus a special dedicated Low-FrequencyEffects (LFE) channel. This represents amajor advancement over traditionalanalog surround in that each surroundchannel is fully discrete and capable offull bandwidth reproduction. DolbyDigital is available on DVD and LV discs,and it will be a part of the new high-definition television (HDTV) systemwhen digital broadcasting begins in1998. Dolby Digital for the home is basedon the same system used to deliver digitalaudio sound tracks in movie theaters,enabling true cinema reproduction inyour home.

To utilize the Dolby Digital mode youmust have a digital source properlyconnected to the AVR45. Connect theDigital datastream outputs from DVDplayers, HDTV receivers and CD players tothe AC-3/PCM Coaxial or Opticalinputs on the rear panel . In orderto provide a backup signal and a sourcefor recording, the analog outputs provid-ed on digital source equipment shouldalso be connected to their appropriateinputs on the AVR45 rear panel (e.g.,connect the analog stereo audio outputfrom a DVD to the DVD inputs on the rear panel when you connect thedigital outputs.)

When playing back a digital source, firstselect the input using the remote or frontpanel controls as outlined above. Nextselect the digital source by pressing theappropriate Digital Input button w and then using the / buttons gon the remote or the Selector buttons on the front panel to choose eitherCOAXIAL or OPTICAL, as it appearsin the Main Information Display S.Press the Set button i to enter thedesired choice. When the digital source isplaying, the AVR45 will automaticallydetect if it is a multichannel DolbyDigital source or a conventional PCMsignal, which is the standard output fromCD players. An indicator will light in theInformation Display to confirm the digi-tal signal is AC-3 H or PCM I and ifthe source is OPTICAL E or COAX G.

When an AC-3 source is playing, theAVR45 will automatically switch to theDolby Digital surround mode. It is impor-tant to note, however, that not all AC-3sources are encoded with the full comple-ment of five channels plus LFE. When adigital source is playing, the MainInformation Display S will change toshow the input source and digital type(OPTICAL or COAX). When a source withDolby Digital encoding is playing, theinput source name will appear in theInformation Display, followed by anumeric key to the type and number of channels being decoded as follows:

Operation

3/2.1: This message appearswhen a full complement of DolbyDigital signals is present: 3 frontchannels (left, center and right), 2 surround channels (surround left and surround right) and 1channel, which is the dedicated LowFrequency Effects (LFE) channel.

3/1: This message indicates theAC-3 system is decoding a standardDolby Pro Logic signal with left,center and right front channels and a signal mono surround channel.

2/0: This message indicates thatthe AC-3 system is decoding a tradi-tional two-channel stereo signal andthat no center, surround or LFEsignals are present.

1+1: This is a monaural signalthat plays the same information inboth the left front and right frontspeakers. There is no sound sent tothe center or surround speakers.

1/0: This is a monaural signalthat plays through the center channelspeaker only. There is no sound at thefront left/right or surround speakers.

Night ModeA special feature of Dolby Digital is theNight mode, which enables AC-3 inputsources to be played back with their fullrange while reducing the minimum peaklevel by 1/4 to 1/3. This prevents abruptlyloud transitions from causing distur-bances without reducing the impact ofthe digital source. The Night mode isavailable only when AC-3 signals withspecial data are being played.

To engage the Night mode, press theNight buttonj on the remote andnote that the NIGHT indicator K willilluminate in the Information Display.

IMPORTANT NOTES ON DOLBY DIGITAL PLAYBACK:

1. When the digital playback unit is in apause, fast forward or chapter searchmode the digital audio data maymomentarily stop, causing a NODATAmessage to be displayed. This isnormal and does not indicate a problemwith either the AVR45 or the sourcemachine. The AVR45 will return to DolbyDigital/AC-3 playback as soon as the datais available when the machine is in astandard play mode.

2. The AVR45 will decode digital audiosources with a sampling frequency of32kHz, 44.1kHz and 48kHz. Althoughthis will enable it to decode virtually allDVD movies and HDTV sources, it is pos-sible that some future digital sourcesmay not be compatible with the AVR45.

NOTE: In order to play the Dolby Digitalsignals that are recorded on laser discs,you must have both a laser disc playerwith an RF output, and an optional,outboard RF-to-data demodulator. Tolisten to Dolby Digital LV discs, connectthe AC-3/RF output of the player to thedemodulator, and connect the output of the demodulator to the Coaxial orOptical inputs on the rear panelof the AVR45. DO NOT connect the AC-3/RF output of a laser disc playerdirectly to the AVR45.

3. Note that not all programs recorded inDolby Digital contain full 5.1 channelaudio. Consult the program guide thataccompanies the DVD or laser disc todetermine which type of audio has beenrecorded on the disc. The AVR45 willautomatically sense the type of digitalsurrround encoding used on an AC-3program source and adjust toaccommodate it.

4. When a Dolby Digital source isplaying, you may not select any of theanalog surround modes.

5. It is not possible to record the outputof a Dolby Digital program.

PCM Audio PlaybackPCM (Pulse Code Modulation) is thenon-compressed digital audio systemused for compact discs and non-AC-3laser discs. The digital circuits in theAVR45 are capable of high-quality digital-to-analog decoding, and they may beconnected directly to the digital audiooutput of your CD or LV player.

Connections should be made to the AC-3/PCM Optical or Coaxial inputs on the rear panel, using whicheverinput is not occupied by an AC-3 sourcesuch as a DVD player.

To listen to a PCM digital source, firstselect the input for the desired source(e.g., CD). Next press the Digital buttonw and then using the / buttonsg on the remote or the Selectorbuttons on the front panel until thedesired choice of either COAXIALorOPTICAL, as it appears in the MainInformation Display S. Press the Setbutton i to enter the desired choice.
