SYSTEM CONFIGURATION 29ENGLISHSystem ConfigurationTo 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 be estab-lished 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 are estab-lished for Dolby Pro Logic IIx – Movie, they willbe carried over to Dolby Pro Logic II – Moviemode. However, you will need to enter the delaysettings separately for each variant mode, such asDolby Pro Logic IIx – Music, Dolby Pro Logic IIx –Game, Dolby Pro Logic, Dolby 3 Stereo and DolbyDigital EX.Delay times are adjustable for all surroundmodes. Although all channels will appear onscreen with the default or previously entered dis-tances, the menu system will only allow you toadjust the settings for those channels which areactually used by the current sur-round mode. Forexample, when you are listening to music CDsusing the CD input in DSP Surround Off mode,you may adjust the delay settings for the frontleft, front right and subwoofer channels only. Thecursor will simply skip the other channels as younavigate through the menu. Therefore, the firsttime you adjust the delay settings, it is recom-mended that you select a 5.1-, 6.1- or 7.1-chan-nel surround mode, depending on the number ofspeakers in your system. For the purposes of set-ting the delay distances, the Logic 7 modes allowaccess to the settings for all channels withoutrequiring that you play a source.To start with the delay settings at first select theDELAY ADJUST MENU (Figure 11). If thesystem is not already at that point, press theOSD button L to bring up the master menu.Press the ¤ Button D three times or until theon-screen ➞ cursor is pointing at the MANUALSETUP line. Press the Set Button F and callup the DELAY ADJUST submenu.Figure 11Next move the ➞ cursor to the UNIT line andselect the unit for distances you prefer to enter,feet or meter. Then move the ➞ cursor to the F Lline where the first adjustment is made. Nowpress the ‹/ › Buttons E until the dis-tance from the front left speaker to the preferredlistening position is entered. Next press the ¤Button D once to move to the next line.Now the ➞ cursor will be at the CEN line sothat the delay for the center speaker may be set.Press the ‹/ › Buttons E until thedistance from the main listening position to thecenter speaker is entered. Repeat the procedurefor all active speaker positions by pressing the ¤Button D again and use the ‹/ › ButtonsE to change the setting. Remember thatthis last adjustment will only be needed whenyou have surround back speakers installed andDolby Digital chosen as the surround mode.When the delay time for all speaker positions hasbeen set you may return to the master menu bypressing the ⁄/¤ Navigation Button Duntil the ➞ cursor is pointing to BACK T OMASTER MENU and then pressing the SetButton F.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. Werecommend that this adjustment be made usingthe direct access controls on the remote, asshown below. That enables you to see the imagewhile making the adjustment; however, you mayalso adjust it here using the menu system.To adjust the A/V Sync delay, press the ⁄/¤Navigation Button D so that the ➞ cursor ispointing to the A/V Sync Delay line on the menuand 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 inthe on-screen display and the Lower DisplayLine ˜. Then, press the ‹/ › NavigationButton E to enter the desired delaysetting that brings the video and sound back insync. Press the Set Button F again to enterthe setting.Note that the A/V Sync delay setting is unique toeach video input source, so you may enter a dif-ferent setting to compensate for the differencesbetween any product attached to the Video 1, 2,3 or 4 inputs.To change one of the individual speaker positionsdirectly, press the Delay Select Button ,followed by the ⁄/¤ Navigation Button Dto select the desired position as that nameappears in the on-screen display and the LowerDisplay Line ˜. When the name of the speakerposition to be adjusted appears press the SetButton F within five seconds. Press the ‹/ ›Navigation Button E to enter thedesired delay setting for that speaker and thenpress the Set Button F to enter the setting.The ⁄/¤ Navigation Button D may beused to select another position, or you maysimply wait five seconds for the system to timeout and return to normal operation.The delay settings may be adjusted at any timeusing the remote control and while viewing anon-screen image by pressing the Delay SelectButton .To change one of the individual speaker positionsdirectly, press the Delay Select Button ,followed by the ⁄/¤ Navigation Button Dto select the desired position as that nameappears in the on-screen display and the LowerDisplay Line Ò. When the name of the speakerposition to be adjusted appears press the SetButton F within five seconds. Press the ‹/ ›Navigation Button E to enter thedesired delay setting for that speaker and thenpress the Set Button F to enter the setting.The ⁄/¤ Navigation Button D may beused to select another position, or you maysimply wait five seconds for the system to timeout and return to normal operation.Output Level AdjustmentOutput level adjustment is a key part of theconfiguration of any surround-sound product. It isparticularly important for a digital receiver suchas the AVR, as correct outputs ensure that youhear sound tracks with the proper directionalityand intensity.NOTE: Listeners are often confused about theoperation of the surround channels. While someassume that sound should always be comingfrom each speaker, most of the time there will belittle or no sound in the surround channels.This is because they are only used when a moviedirector or sound mixer specifically places soundthere to create ambience, a special effect or tocontinue action from the front of the room to therear. When the output levels are properly set, itis normal for surround speakers to operate onlyoccasionally.
