47ADVANCED FUNCTIONSPress the Set Button to access the Surround Setup menu, as shown inFigure 81. With the Surround Mode highlighted, press the Set Buttonto change the surround mode group. Use the ‹/› Buttons to scrollthrough the options, and press the Set Button when the desired modegroup appears. Navigate to the Mode line and follow the same procedureto select an individual mode. The Upsampling setting is only available forthe Dolby modes. You may wait for the full-OSD screen to time-out anddisappear from view, or press the ‹ Button to return to the menu tabsand select another menu.Dolby Surround SettingsSome additional settings are available for Dolby modes. Three settingsare active only when the Dolby Pro Logic II or IIx Music modes havebeen selected. See Figure 83.Figure 83 – Dolby Pro Logic IIx Music Mode SettingsCENTER WIDTH: This setting affects how vocals sound through thethree front speakers. A higher number (up to 7) focuses the vocal infor-mation tightly on the center channel. Lower numbers broaden the vocalsoundstage across the three speakers.DIMENSION: This setting affects the depth of the surround presenta-tion, allowing you to “move” the sound toward the front or rear of theroom. The setting of “0” is a neutral default. Setting “F-3” moves thesound mostly toward the front of the room, while setting “R-3” movesthe sound mostly toward the rear.PANORAMA: With the Panorama mode turned ON, some of the soundfrom the front speakers is moved to the surround speakers, creating anenveloping “wraparound” type of effect.UPSAMPLING: The last line of the Surround Select menu activatesupsampling, only available with the Dolby Pro Logic II/IIx Movie, DolbyPro Logic II/IIx Music and Dolby Pro Logic modes. Normally set to OFF,upsampling, when activated, processes digital sources at a higher reso-lution for improved sound quality. This feature can be useful to eliminatedistortion in some low-resolution sources.Night ModeNight mode is available with some Dolby Digital programs, if it has beenencoded in the material. It compresses the peak sound levels, maintain-ing the intelligibility of the dialogue and quieter passages, while reducingthe loudness of special effects and louder passages to avoid disturbingothers. Three levels of compression are available:OFF: At this setting, there is no compression, as the Night mode isdeactivated.MID: A mild compression is applied.MAX: More compression is applied.We suggest that you experiment with the modes to find a setting thatmeets your needs.The Night mode is not adjusted using the full-OSD menu system. Witha Dolby Digital program encoded with Night mode playing, press theNight Button on the remote. Each press of the button will cycle throughthe three settings, with the selected setting being displayed on the frontpanel and in the semi-OSD display.Default ModesDuring initial use or after a processor reset, the AVR 247 will defaultto the Logic 7 7CH Music mode for all analog and PCM audio inputs.Subsequently, when a source input is selected and an analog or PCMsignal is received, the AVR will switch to the last surround mode usedfor that source input/incoming signal combination.Whenever a multichannel Dolby Digital or DTS signal is detected, theAVR 247 will automatically switch to that mode, unless the DEFAULTSURROUND setting in the System Setup menu has been changed to OFF.You may observe that other surround modes are available for use with themultichannel digital bitstreams. If you would prefer the AVR 247 to useone of those alternate modes any time the same digital signal is detected,then select that mode while the multichannel bitstream is present, andthen change the DEFAULT SURROUND setting in the System Setupmenu to OFF.Table 8 provides descriptions of all surround modes available on theAVR 247, along with the incoming bitstreams or signals that the particularmode may be used with. Feel free to experiment and simply cyclethrough all of the available modes at any time; you cannot cause anyproblems for the AVR 247 by doing so.NOTE: In order to access 6.1- and 7.1-channel modes, suchas Dolby Digital EX, DTS-ES, Logic 7 (7.1 modes), DTS Neo:6(6.1 modes), the 6-channel implementations of Hall 1, Hall 2and Theater and 7-channel Stereo, you must enable thesurround back channels as explained in the Manual Setupsection. You should not enable these channels if you don’thave surround back speakers in your system.
