SYSTEM CONFIGURATION 23System Configurationpensate 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.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)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, suchas Dolby Pro Logic IIx – Music, Dolby Pro LogicIIx – Game, Dolby Pro Logic, Dolby 3 Stereo andDolby Digital 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.When your system includes a surround backspeaker, delay distances should be entered twicefor this speaker, once for the surround back leftchannel, and again for the surround back rightchannel. This enables the mixing circuit that com-bines the signals for these channels when a 7.1-channel surround mode is in use to output theinformation correctly.To start with the delay settings at first select theDELAY ADJUST MENU (Figure 9). 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 andcall up the DELAY ADJUST submenu.Figure 9Next move the cursor to the UNIT line andselect the unit for distances you prefer to enter,feet or meter. Then move the cursor to theF L line 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 the dis-tance 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.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 speak-er position 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 may sim-ply wait five seconds for the system to time outand return to normal operation.Output Level AdjustmentOutput level adjustment is a key part of theconfiguration of any surround-sound product. Itis particularly 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. Thisis 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 tothe rear. When the output levels are properlyset, it is normal for surround speakers tooperate only occasionally. Artificially increasingthe volume to the rear speakers may destroy theillusion of an enveloping sound field that dupli-cates the way you hear sound in a movie theateror concert hall.When the AVR is configured for 6.1-channeloperation using a single surround back speaker,the output level adjustments will still provide anadjustment for separate surround back left andsurround back right positions even though yoursystem has only one surround back speaker. Thismeans that the Surround Back channel will seemto appear twice, and in 6.1 operation this is nor-mal. The separate SBL/SBR adjustments for 6.1operation are needed to optimize the balancebetween the two discrete channels within theAVR as they are mixed for output to a singlespeaker.IMPORTANT NOTE: The output level can beadjusted for each digital and analog surroundmode individually. This allows you to compensatefor level differences between speakers, that mayalso vary with the surround mode selected, or toincrease or decrease the level of certain speakersintentionally, depending on the surround modeselected. Note that adjustments made for anysurround mode are effective with all inputs asso-ciated with the same surround mode.* DELAY ADJUST *F L : 1 0 F T S B R : 1 0 F TC E N : 1 0 F T S B L : 1 0 F TF R : 1 0 F T S L : 1 0 F TS R : 1 0 F T S U B : 1 0 F TD E L A Y R E S E T : O F FU N I T : F E E TB A C K T O M A N U A L S E T U P
