SYSTEM CONFIGURATION 29System ConfigurationWhen any needed adjustments are made to thecrossovers, one additional adjustment is availableto custom tailor the way information is sent to thesubwoofer. The LFE LP FLT line adjusts thefrequency cutoff of the low pass filter that deter-mines the frequency at which information is sentto the subwoofer when playing a digital sound-track that has a dedicated low frequency effectschannel. In most cases the default frequency of120Hz is appropriate, since that is the frequencymost commonly used in the creation of LFE chan-nels during a movie’s sound mixing process.However, you may wish to change the settingbased on your individual preference or the charac-teristics and capabilities of your subwoofer.To change this setting when the SPEAKERX-OVER menu is on the screen, press the⁄/¤ Navigation Button E until the cursoris on the LFE LP FLT line and then pressthe ‹/› Navigation Button E until thedesired setting is shown in highlighted video.When all changes to Speaker Crossover settingshave been made, press the ⁄/¤ NavigationButton E until the cursor is on the BACKT O MANUAL SETUP menu and then press-ing the Set Button F so that you may makeany other adjustments to the system parameters.It is also important to remember to rerun theEzSet/EQ system if any changes have been madeto the settings on this menu, following theinstructions shown on page 26 for using theManual mode.The Speaker Configuration may also be changedat any time without using the full-OSD on-screenmenu system by pressing the Speaker Selector6 on the front panel or ' on the remote con-trol. Once the button is pressed, FRONTSPEAKER will appear in both the lower thirdof the video display and the Main InformationDisplay ˜.Within five seconds, either press the ‹/› buttons7 $ on the front panel or the ⁄/¤ buttonsE on the remote to select a different speakerposition, or press the Set Button @F to beginthe adjustment process for the front left and rightspeakers.When the Set button @ F has been pressedand the system is ready for a change to the frontspeaker setting, the on-screen display and MainInformation Display ˜ will read FRONTLARGE or FRONT SMALL depending onthe current setting. Press the ‹/› buttons 7 $on the front panel or the ⁄/¤ buttons E onthe remote until the desired setting is shown,using the instructions for “large” or “small”shown earlier, then press the Set button @F.If another speaker position needs to be changed,press the ‹/› buttons 7 $ on the front panelor the ⁄/¤ buttons E on the remote to selecta different speaker position, press the Set button@ F and then the ‹/› buttons 7 $ on thefront panel or the ⁄/¤ buttons E on theremote until the correct speaker setting is shownand press the Set button @ F again to con-firm the selection.To assist in making these settings, the icons in theSpeaker/Channel Input Indicators Ú willchange as the speaker type is selected at eachposition. When only the inner icon box is lit, thespeaker is set for “small.” When the inner box andthe two outer boxes with circles inside them arelit, the speaker is set for “large." When no indica-tor appears at a speaker location, that position isset for “none” or “no” speaker.Note: These icons are available only whenmaking setup changes without the use of the fullOSD mode.As an example, in the Figure below, all speakersare set for “large,” and a subwoofer is set.Delay SettingsDue the different distances between the listeningposition for the front channel speakers and thesurround speakers, the amount of time it takes forsound to reach your ears from the front or sur-round speakers is different. You may compensatefor this difference through the use of the delaysettings to adjust the timing for the specificspeaker placement and acoustic conditions in yourlistening room or home theater.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) speak-ers in meters.If you have already calibrated your system usingEzSet/EQ the delay settings shown will reflect theresults of the measurements made by EzSet/EQ.No further changes are needed unless you wish tochange an item to reflect your taste or a nonstan-dard system configuration. To change the settings,follow the instructions below to enter the distancebetween the speaker’s location and your main lis-tening position. The measurements need not beaccurate to the inch, as the system is designed toaccommodate typical listening rather than a spe-cific “sweet spot” position.In addition to adjusting the delay time for eachindividual speaker position, the AVR is among thefew A/V receivers that allows you to adjust thedelay for the combined output of all speakers as agroup. This feature is called A/V Sync Delay; itallows you to compensate for delays to the videoimage that may be caused by the processing inproducts such as digital video displays, videoscalers, digital cable or satellite systems, or per-sonal video recorders. With proper adjustment ofthe setting for A/V Sync Delay, you can eliminatethe loss of lip sync that may be caused by digitalvideo applications.The Delay setting for all speakers configured foryour system will be available only (with 5.1 orwith 6.1/7.1 configuration) when any Dolby sur-round mode is selected (except Dolby-3-Stereo).In addition they are selectable with these modesonly, with all other modes the delay times arefixed. Note that the Delay settings are "Global"for all inputs, using those Dolby modes, and neednot to be repeated with any input.
