18 SYSTEM CONFIGURATIONSystem Configurationto digital sources. In the case of inputs such as aCD Player, Tape Deck or Tuner, you may wish toset the mode to Stereo, if that is your preferredlistening mode for standard stereo sources, whereit is unlikely that surround encoded material willbe used. Alternatively, the 5 Channel Stereo orLogic 7 Music mode may also be a good choicefor stereo-only source material.It is easiest to complete the surround setup usingthe full-OSD on-screen menus. From theMASTER menu (Figure 1), press the ⁄/¤buttons D until the cursor is next to theSURROUND SELECT menu. Press theSet Button F so that the SURROUNDSELECT menu (Figure 3) is on the screen.Figure 3Each of the option lines on this menu (Figure 3)selects the surround mode category, and withineach of those categories there will be a choice ofthe specific mode options. The choice of modeswill vary according to the speaker configurationin your system.When the SURR BACK line of theSPEAKER SETUP menu (Figure 7) is set toNONE the AVR will be configured for5.1-channel operation, and only the modesappropriate to a five-speaker system will appear.When the SURR BACK line of the SPEAK-E R SETUP menu (Figure 7) is set to SMALLor LARGE the AVR will be configured for6.1/7.1-channel operation, and additional modessuch as Dolby Digital EX and 7 STEREO or Logic 77.1 will appear. In addition, the modes DTS ES(Discrete) and DTS+NEO:6 (DTS ES Matrix) avail-able in the AVR 140 will not appear unless a digi-tal source is playing the correct bitstream.In addition, some of the modes available in theAVR will not appear unless a digital source isselected and is playing the correct bitstream.Remember that when you use only a single, sur-round back speaker, you will get the benefits of a6.1/7.1 system, but with only one speakerinstalled at the back of the room. The mode indi-cations will show 7.1 in some cases, but no addi-tional adjustment is needed for 6.1 operation.Remember that the AVR will combine the left andright surround back channel information presentin 7.1 modes such as Logic 7/7.1 and 7-channelstereo, outputting the information as a single sur-round back channel.Note: When a Dolby Digital or DTS source isselected and playing, the AVR will select theappropriate surround mode automatically, nomatter which surround mode was selected forthat input as default. Then no other surroundmodes will be available, except VMAx with DolbyDigital recordings and all Pro Logic II modes withDolby Digital 2 channel (2.0) recordings (seepage 29).To select the mode that will be used as the initialdefault for an input, first press the ⁄/¤ buttonsD until the on-screen cursor is next to thedesired mode’s master category name. Next,press the Set Button F to view the sub-menu. Press the ‹/› Buttons E to scrollthrough the available choices, and then press the¤ Button D so that the cursor is next toBACK TO MASTER MENU to continue thesetup process.On the DOLBY SURROUND menu (Figure4), the selection choices include Dolby Digital,Dolby Pro Logic II or llx Music, Dolby Pro Logic IIor llx Cinema, Dolby Pro Logic II and Dolby 3Stereo. The Dolby Digital EX and Dolby Pro LogicIIx modes are only available when the system isset for 6.1/7.1 operation by configuring theSurround Back speakers to “Small” or “Large” asdescribed on page 21. When a disc is playing thatcontains a special “flag” signal in the digitalaudio data stream, the EX mode will be selectedautomatically. It may also be selected using thismenu or through the front panel or remote con-trols as shown on page 29. A complete explana-tion of these modes is found on Page 26-27.Note that when the Dolby Digital mode is select-ed there are additional settings available for theNight mode that are associated with the sur-round mode only, not with the input. That´s whythese settings must be made only once, not witheach input in use. They are described later in thenext main chapter (see below).Figure 4When the cursor is pointing to the MODEline, press the ‹/› Navigation ButtonsE to select the desired Dolby surroundmode, again remembering that the choice ofavailable modes will vary with the type of pro-gram material being played and the number ofspeakers in your system configuratioin.When Dolby Pro Logic II Music or Dolby Pro LogicIIx Music is selected as the listening mode, threespecial settings are available to tailor the soundfield to your listening room environment and yourindividual taste and preferences. (When otherDolby Surround modes are selected, dotted lineswill indicate that these settings are not active.)• Center Width: This setting adjusts the balanceof the vocal information in the front sound-stage between the center and front left/rightspeakers. The lower settings spread the centerchannel sound more broadly into the left andright channels. A higher number (up to “7”)produces a tighter center channel presenta-tioin.• Dimension: This setting alters the perceiveddepth of the surround field by creating a shal-lower presentation that appears to movesounds toward the front of the room, or adeeper presentation that appears to move thecenter of the sound field toward the back ofthe room. The setting of “O” is a neutraldefault, with the range of adjustment shown as“R-3” for a deeper, rear-oriented sound to“F-3” for a shallower, front-oriented sound.• Panorama: Switch this setting on or off to addan enveloping wrap-around presentation thatincreases the perception of sound along thesides of the room.To change these parameters, press the ⁄/¤Navigation Buttons D while the DOLBYSURROUND menu is on the screen until the cursor is pointing to the line on the menu withthe parameter you wish to change. Then, pressthe ‹/› Navigation Buttons E to alterthe setting to your taste.Note that when the Dolby Digital mode is select-ed there are additional settings available for theNight mode that are associated with the sur-round mode only, not with the input. That´s whythese settings must be made only once, not witheach input in use.Night Mode SettingsThe Night mode is a feature of Dolby Digital thatuses special processing to preserve the dynamicrange and full intelligibility of a movie sound trackwhile reducing the peak level. This preventsabruptly loud transitions from disturbing others,without reducing the sonic impact of a digitalsource. Note that the Night mode is only availablewhen the Dolby Digital surround mode is select-ed.To adjust the Night mode setting from the menupress the OSD Button L so that theMASTER menu appears. Then press the ¤button D to access the AUDIO SETUP andpress Set F to select the SURROUNDSETUP menu. Press Set F to select theDOLBY menu (see fig. 5).* DOLBY SURROUND *MODE:DOLBY PLIIx MUSICCENTER WIDTH:3DIMENSION :0PANORAMA :OFFNIGHT :----UPSAMPLING :OFFBACK TO SURROUND SELECT* S U R R O U N D S E L E C T *D O L B Y S U R R O U N DD T SL O G I C 7D S P ( S U R R )V M A xS T E R E OB A C K T O M A S T E R M E N U
