28 SYSTEM CONFIGURATIONSystem ConfigurationTo change the setting for any of the four speakergroups Left/Right, Center, Surround or SurroundBack, press the ⁄/¤ Buttons D until the cur-sor is next 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, Center,Surround and Surround Back speakers are usedto determine where bass information is sentwhen it is derived from the main channels of asource. The setting for the menu line shown asLFE is used to impose a low-pass filter point forthe information in the Low Frequency Effects(LFE) channel that is a part of Dolby Digital- andDTS-encoded source material. While the LFEchannel, which is the “.1” you see in surroundsound designations, is restricted to low fre-quen-cy sounds, some mixes may include informationthat is higher in frequency than your subwoofer iscapable of reproducing. To prevent unwantedsounds from being sent to subwoofers thatcannot handle them and which do not have abuilt-in low-pass filter, the LFE option lineenables you to select a setting for the low-passfilter that is part of the subwoofer feed from theLFE channel. The settings available are the sameas those tied to any one of the four availablespeaker positions on this submenu. We recom-mend that you use the frequency that is justslightly higher than the upper capability limit ofyour subwoofer, as shown in the sub’s Owner’sManual. When the cursor is on the LFE line,press the ‹/› Navigation Buttons E tochoose 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.If you have already calibrated your system usingEzSet+ the delay settings shown will reflect theresults of the measurements made by EzSet+. Nofurther changes are needed unless you wish tochange an item to reflect your taste or a nonstan-dard system configuration. To change the set-tings, follow the instructions below to enter thedistance between the speaker’s location and yourmain listening position. The measurements neednot be accurate to the inch, as the system isdesigned to accommodate typical listening ratherthan a specific “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 asa group. 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.Although EzSet+ calculates the delay settings forthe 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+ for other delay settings,the A/V Sync Delay should still be configured asoutlined below.
