32 SYSTEM CONFIGURATIONAs an example, in the Figure below, all speakersare set for “large,” and a subwoofer is set.Delay SettingsDue the different distances between thelistening position for the front channel speakersand the surround speakers, the amount of time ittakes for sound to reach your ears from the frontor surround speakers is different. You maycompensate for this difference through the useof the delay settings to adjust the timing for thespecific speaker placement and acousticconditions in your listening room or hometheater.If you have already calibrated your system usingEzSet/EQ the delay settings shown will reflectthe results of the measurements made byEzSet/EQ. No further changes are needed unlessyou wish to change an item to reflect your tasteor a nonstandard system configuration. Tochange the settings, follow the instructionsbelow to enter the distance between thespeaker’s location and your main listeningposition. The measurements need not beaccurate to the centimeter, as the system isdesigned to accommodate typical listeningrather than a specific “sweet spot” position.In addition to adjusting the delay time for eachindividual speaker position, the AVR is amongthe few A/V receivers that allows you to adjustthe delay for the combined output of allspeakers as a group. This feature is called A/VSync Delay; it allows you to compensate fordelays to the video image that may be caused bythe processing in products such as digital videodisplays, video scalers, digital cable or satellitesystems, or personal video recorders. With properadjustment of the setting for A/V Sync Delay, youcan eliminate the loss of lip sync that may becaused by digital video applications.Although EzSet/EQ calculates the delay settingsfor the individual speaker positions with veryaccurate results, the setting for A/V Sync Delaymay only be done manually, since it requires thatyou observe the program material on your videodisplay while adjusting the delay, if any, requiredfor the specific source. Thus, even though youmay have used EzSet/EQ for other delay settings,the A/V Sync Delay should still be configured asoutlined below.To re-synchronize the front, center and surroundchannels at first measure and note the distancefrom the listening/viewing position to the front,center, surround and surround back (if any)speakers in meters.Due to the differences in the way each surroundmode operates, the delay settings must beestablished individually for each surround mode.However, once the delay settings are configuredfor the version of the surround mode with themost channels, they need not be entered againfor a version of that mode with fewer channels.For example, once the delay settings areestablished for Dolby Pro Logic IIx – Movie, theywill be carried over to Dolby Pro Logic II – Moviemode. However, you will need to enter the delaysettings separately for each variant mode, suchas Dolby Pro Logic IIx – Music, Dolby ProLogic IIx – Game, Dolby Pro Logic,Dolby 3 Stereo and Dolby Digital EX.Delay times are adjustable for all surroundmodes. Although all channels will appear onscreen with the default or previously entereddistances, the menu system will only allow youto adjust the settings for those channels whichare actually used by the current surround mode.For example, when you are listening to musicCDs using the CD input in DSP Surround Offmode, you may adjust the delay settings for thefront left, front right and subwoofer channelsonly. The cursor will simply skip the otherchannels as you navigate through the menu.Therefore, the first time you adjust the delaysettings, it is recommended that you select a5.1-, 6.1- or 7.1-channel surround mode,depending on the number of speakers in yoursystem. For the purposes of setting the delaydistances, the Logic 7 modes allow access to thesettings for all channels without requiring thatyou play a source.To start with the delay settings at first select theSPEAKER SETUP - Delay (Figure 28).If the system is not already at that point, pressthe OSD button L to bring up the mainmenu. Press the ¤ Button D twice or untilthe Speaker -tab is highlighted in white.Press the Set Button F twice, followed bythe ¤ Button D until the Delay Adj-line is highlighted in blue. Press Set F toaccess the menu.Figure 28Next move the blue bar down to the Unitline, press Set F and select the unit for dis-tances you prefer to enter, feet or meter with theuse of the ‹/ › Buttons E. Then movethe blue bar to the Front Left line wherethe first adjustment is made, and press the SetButton F. Now press the ‹/ › ButtonsE until the distance from the front leftspeaker to the preferred listening position isentered followed by the Set Button F toconfirm your choice. Next press the ¤ ButtonD once to move to the next line.Now the blue bar will highlight the Center-line so that the delay for the center speaker maybe set. Press Set F followed by the the ‹/ ›Buttons E until the distance from themain listening position to the center speaker isentered. Repeat the procedure for all activespeaker positions by pressing the ¤ ButtonD again and use the ‹/ › Buttons Eto change the setting. Remember that this lastadjustment will only be needed when you havesurround back speakers installed and DolbyDigital chosen as the surround mode.When the delay time for all speaker positionshas been set you may return to the main menuby pressing the ‹ Navigation Button Eseveral times.However, if you have a digital video source or adigital video display that causes lack of lip syncyou may use the A/V Sync adjust feature to delaythe audio signal as it is sent to all channels (asopposed to the individual settings) so that thepicture and sound are brought back together.We recommend that this adjustment be madeusing the direct access controls on the remote,as shown below. That enables you to see theimage while making the adjustment; however,you may also adjust it here using the menusystem.To adjust the A/V Sync delay, press the ⁄/¤Navigation Button D so that the blue bar ishighlighting the A V Sync Delay-line onthe menu, followed by the Set Button F,and then press the ‹/ › Navigation ButtonE to delay the sound sufficiently so that itmatches the on-screen video.The delay settings may be adjusted at any timeusing the remote control and while viewing anon-screen image by pressing the Delay SelectButton . The A/V Sync Delay setting is first,and it may be adjusted by pressing the SetButton F within five seconds of when theA/V SYNC DELAY message appears in theon-screen display and the Lower Display LineM. Then, press the ⁄/¤ Navigation ButtonD to enter the desired delay setting thatbrings the video and sound back in sync. Pressthe Set Button F again to enter the setting.System Configuration
