24 SYSTEM CONFIGURATIONSystem ConfigurationWhen no indicator appears at a speaker loca-tion, that position is set for “none” or “no”speaker.Note: These icons are available only when mak-ing setup changes in the semi-OSD mode.As an example, in Figure 6 below, the left frontand right front speakers are set for “large,” thecenter, left surround (LS) and right surround (RS)speakers are set for small, and a subwoofer isset, as shown by the box with the abbreviation“LFE”, which stands for “low frequency effects”.Figure 6Adjustments for Other InputsAfter one input has been adjusted for surroundmode, digital input (if any) and speaker type goback to the INPUT SETUP line on themain AUDIO SETUP menu and enter thesettings for each input that you will use. In mostcases, only the digital input and surround modewill be different from one input to the next, whilethe speaker type will usually be the same andmay be quickly entered by entering the samedata used for the original input.Settings independent from InputsselectedAfter the settings described above are made forall input sources in your system, the followingsettings, made with any input, will be effectivefor all inputs selected.Again to make these settings the best the fullOSD menu system should be used. From theAUDIO SETUP menu (Figure 1) move thecursor to the SURROUND SETUP lineand press the Set 8 button to bring up theSourround Setup menu.Depending on the surround mode selected, youwill now proceed to change either the delay timeor the crossover frequency. For Dolby Digital andDolby Pro Logic, pressing the ⁄/¤ buttons 6will take you to the delay settings, for all othermodes, it will take you to the CrossoverFrequency adjustment.Delay SettingsIf Dolby Digital or Dolby Pro Logic is selected, youwill need to adjust the delay time setting. Notethat the delay time is not adjustable for anyother modes.Important Note: Once the delay time is setwith any input it will be effective with all otherinputs too. Moreover the surround delay timesetting must be made only for either the DolbyPro Logic or the Dolby Digital mode. The othersetting will be set automatically.Due the different distances between the frontchannel speakers and the listening position com-pared to the surround speakers and the listeningposition, the amount of time it takes for sound toreach your ears from the front or surround speak-ers is different. You may compensate for this dif-ference through the use of the delay settings toadjust the timing for the specific speaker place-ment and acoustic conditions in your listeningroom or home theater.The factory setting is appropriate for most rooms,but some installations create an uncommon dis-tance between the front and surround speakersthat may cause the arrival of front channelsounds to become disconnected from surroundchannel sounds.To resynchronize the front and surround chan-nels, follow these steps:1. Measure the distance from the listening/ view-ing position to the front speakers in meters.2. Measure the distance from the listening/ view-ing position to the surround speakers.3. Subtract the distance to the surround speakersfrom the distance to the front speakers and multi-ply the result by 3.a. When setting the delay time for the DolbyDigital surround modes, the optimal delay timeis the result of that subtraction. For example, ifthe front speakers are 3 m away and the sur-round speakers are 1 m away, the optimaldelay time is figured as (3–1)x3=6. Thus, inthis example, the delay time for Dolby Digitalshould be set at six milliseconds.b. When setting the delay time for the Pro Logicmode, take the result of the subtraction andadd 15 to obtain the optimal delay time. Forexample, if the front speakers are 3 m awayand the surround speakers are 1 m away, theoptimal delay time is figured as(3–1)x3+15=21. Thus, in this example, the ProLogic delay should be set at twenty millisec-onds.NOTE: The DTS, Logic 7, Hall and Theater modesuse a fixed, nonadjustable delay time.The Dolby Digital Mode also includes a separatesetting for the center channel delay mode, sincethe discrete nature of these signals makes thelocation of the center channel speaker more criti-cal. To calculate the delay for the center channel,measure the distance from the preferred listeningposition in the center of the room to both thecenter channel speaker and either the left orright speaker.If the distances are equal, no further adjustmentis required and the center delay should be set tozero. If the distance to the front speakers isgreater than the distance to the center speaker,you may wish to reposition the speakers by mov-ing the front left and front right speakers closer tothe listening position or the center speaker furtheraway from the listening position.If repositioning of the speakers is not possible,adjust the center delay time, adding one milli-second of center channel delay for every 30 cmcloser to the listening position the center speakeris than the front speakers. For example, if thefront left and front right speakers are each 3 mfrom the listening position and the center chan-nel speaker is 2.4 m away, the delay is figured as300 cm –240 cm=60 cm, suggesting an optimalcenter delay of 2 milliseconds.To set the delay time, continue within the mainAUDIO SETUP (Figure 1) menu. If thesystem is not already at that point, press theOSD button I to bring up the main audiosetup menu.To make the delay settings for theDolby Digital mode (this will include the Centerdelay setting, and the surround delay for the ProLogic mode will be set automatically), press theSet 8 button and select any input now that isassociated with a digital input and the DolbyDigital surround mode, then return to the mainmenu. Press the ¤ button 6 and then the Setbutton 8 to bring up the surround setupmenu, now select the Dolby Digital mode, if notso already and then press the ¤ button 6once.As the Dolby Digital mode is selected, the › cur-sor will stop at the CENTER DELAY line.Press the ‹/› buttons 9 until the desiredfigure appears in the display, using the numbercalculated using the formula shown above. Whenthe CENTER DELAY is entered, press the¤ button 6 once to move to the SURRDELAY line so that the delay for the surroundspeakers may be set. Press the ‹/› buttons9 until the desired figure appears in thedisplay, using the number calculated using theformula shown above for the Dolby Digital sur-round mode (item 3a). When the delay settingsare complete, press the ¤ button 6 once tomove to the next line.L R
