24 SYSTEM CONFIGURATIONSystem Configurationor where different brands or models are in use atthe various speaker positions, this feature allowsyou to custom tailor the bass management andredirection circuits with a precision not previouslypossible.If you have already run EzSet the settings calculat-ed during that procedure will already appear. Nofurther adjustment is required unless you wish toconform a specific item to your personal taste or anonstandard system configuration.The low-frequency crossover point is set by thedesign of your speakers. It is defined as the frequen-cy which is the lowest possible frequency the speak-er is capable of reproducing. Before making anychanges to the settings for the crossover point wesuggest that you find the crossover point for thespeakers in each of the three groupings, frontleft/right, center front and surrounds by looking atthe specifications page of the speaker’s owner’smanual, by getting that information from the manu-facturer’s Web site, or by contacting your dealer orthe manufacturer’s customer service department.You will need this figure to accurately configure thenext group of settings.The factory default setting for all speaker positions is100Hz. If that setting is acceptable for all channels,then no adjustments are needed and you may skipthis section. However, should you wish to changeone of the settings, please proceed to theSPEAKER X-OVER submenu, as shown inFigure 10.Figure 10To change the setting for any of the threespeaker groups Left/Right, Center or Surround,press the ⁄/¤ Buttons D until the cursor isnext to the line where you wish to make achange and then press the ‹/› Buttons Euntil the desired setting appears. The availablechoices at which point low-frequency informationwill be sent to the subwoofer (or to the FrontLeft/Right speakers in case subwoofer is set toOFF), rather than to the speaker channel, are40Hz, 60Hz, 80Hz, 100Hz, 120Hz, 150Hz and200Hz. Pick the choice that is identical to theinformation for the speakers, or if an exact matchis not possible, pick the closest choice that isABOVE the speaker’s lowfrequency limit to avoidthe creation of a low-frequency “hole” whereyour system will have no bass information.In cases where LARGE has been selected as thefront channel speaker option and L/R+LFEhas been selected as the subwoofer option, thefront channel sound information below the cross-over point selected for the L/R front speakers(when fronts are set to "Small") will be sent toBOTH the front channel speakers and the sub-woofer.The crossover settings for the Left/Right, Centerand Surround speakers are used to determinewhere bass information is sent when it is derivedfrom the main channels of a source. The settingfor the menu line shown as LFE is used toimpose a low-pass filter point for the informationin the Low Frequency Effects (LFE) channel that isa part of Dolby Digital- and DTS-encoded sourcematerial. While the LFE channel, which is the“.1” you see in surround sound designations, isrestricted to low fre-quency sounds, some mixesmay include information that is higher in frequen-cy than your subwoofer is capable of reproduc-ing. To prevent unwanted sounds from being sentto subwoofers that cannot handle them andwhich do not have a built-in low-pass filter, theLFE option line enables you to select a settingfor the low-pass filter that is part of the sub-woofer feed from the LFE channel. The settingsavailable are the same as those tied to any oneof the four available speaker positions on thissubmenu. We recommend that you use the fre-quency that is just slightly higher than the uppercapability limit of your subwoofer, as shown inthe sub’s Owner’s Manual. When the cursor is onthe LFE line, press the ‹/› NavigationButtons E to choose the appropriate setting.Note that the crossover point for the surroundspeakers and the surround back speakers will beidentical. That´s why no crossover point for thesurround back speakers is selectable or shown inthe menu.Important Note: All settings for the crossoverpoints will be "Global", i.e. they will be identicalfor all inputs no matter if the BASSMANAGER(see above) was configured for "Global" or"Independent".10. When all speaker selections have been made,press the ¤ Button D until the cursor is nextto the BACK T O MANUAL SETUP line andpress the Set Button F to return to theManual setup submenu.11. The Speaker Configuration may also bechanged at any time without using the full-OSDon-screen menu system by pressing the SpeakerSelector 6 on the front panel or on theremote control. Once the button is pressed,FRONT SPEAKER will appear in both thelower third of the video display and the MainInformation Display Ò.Within five seconds, either press the ‹/› buttons7 on the front panel or the ⁄/¤ buttons Don the remote to select a different speakerposition, or press the Set Button @F tobegin the adjustment process for the front leftand right speakers.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 Ò will read FRONTLARGE or FRONT SMALL depending onthe current setting. Press the ‹/› buttons 7 onthe front panel or the ⁄/¤ buttons D on theremote until the desired setting is shown, usingthe instructions for “large” or “small” shownearlier, then press the Set button @F.If another speaker position needs to be changed,press the ‹/› buttons 7 on the front panel orthe ⁄/¤ buttons D on the remote to select adifferent speaker position, press the Set button@ F and then the ‹/› buttons 7 on thefront panel or the ⁄/¤ buttons D on theremote until the correct speaker setting is shownand press the Set button @ F again toconfirm the selection.To assist in making these settings, the icons inthe Speaker/Channel Input Indicators $will change as the speaker type is selected ateach position. When only the inner icon box is lit,the speaker is set for “small.” When the inner boxand the two outer boxes with circles inside themare lit, the speaker is set for “large." When noindicator appears at a speaker location, that posi-tion is set 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 takesfor sound to reach your ears from the front orsurround speakers is different. You may compen-sate for this difference through the use of thedelay settings to adjust the timing for the specificspeaker placement and acoustic conditions inyour listening room or home theater.30935_AVR145_ENG 01/12/06 9:53 Side 24
