SYSTEM CONFIGURATION
the AVR 240 will not appear unless a digital source is selected and is playing the correct bitstream. Remember that when 6.1-channel program material is playing, the same information will be heard through both of the surround back speakers. To select the mode that will be used as the initial default for an input, first press the � / ¤ Buttons n until the on-screen cursor is next to the desired mode�s master category name, such as DOLBY, DTS, DSP(SURR) or VMAx. Next, press the Set Button p to view the submenu. Press the �/� Buttons o to scroll through the available choices, and then press the ¤ Button n so that the cursor is next to BACK TO MASTER MENU to continue the setup process. The following few paragraphs detail the instructions for surround mode categories with several mode options or with other available settings. On the DOLBY SURROUND menu (Fig. 5), choices include Dolby Digital, Dolby Pro Logic II (Movie, Music and Game), Dolby Pro Logic IIx (Movie, Music and Game) and Dolby Pro Logic. For a complete description of the different Dolby Surround modes, see pages 33�34. The Dolby Digital EX and Dolby Pro Logic IIx modes are only available when the system is set for 6.1/7.1 operation by configuring the Surround Back speakers to SMALL or LARGE, as described on page 26. When a disc is playing with a Dolby Digital soundtrack that contains a special �flag� signal in the data stream, the Dolby Digital EX mode will be selected automatically. It may also be selected using this menu or through the front-panel or remote controls, as shown on page 32.

ing both the Dolby Digital mode and the second mode, separated by a plus sign (e.g., DOLBY D+DOLBY PRO LOGIC II MUSIC). Keep in mind that the Dolby Digital EX and Dolby Pro Logic IIx modes are only available when the AVR is set for 6.1/7.1 operation by configuring the Surround Back speakers to �Small� or �Large,� as described on page 26. When a disc is playing that contains a special data �flag� in the digital audio data stream, the Dolby Digital EX mode will automatically be selected. This mode may also be selected using this menu or through the front-panel or remote controls, as shown on page 32. A complete selection of the available Dolby surround modes is on pages 33�34. When Dolby Pro Logic II Music or Dolby Pro Logic IIx Music is selected as the listening mode, three special settings are available to tailor the sound field to your listening room environment and your individual taste and preferences. (When other Dolby Surround modes, such as Dolby Pro Logic II Movie, are selected, dashed lines will indicate that these settings are not active.) � Center Width: This setting adjusts the balance of the vocal information in the front soundstage, between the center and front left/right speakers. The lower settings spread the center channel sound more broadly into the left and right channels. A higher number (up to �7�) produces a tighter center channel presentation. � Dimension: This setting alters the perceived depth of the surround field by creating a shallower presentation that appears to move sounds toward the front of the room, or a deeper presentation that appears to move the center of the sound field toward the back of the room. The setting of �0� is a neutral default, 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 add an enveloping wraparound presentation that increases the perception of sound along the sides of the room. To change these parameters, press the ¤ Button n while the DOLBY SURROUND submenu is on the screen until the � cursor is pointing to the line on the menu with the parameter you wish to change. Then, press the �/� Buttons o to alter the setting to your taste. When a Dolby Digital source is playing and the DOLBY DIGITAL mode is selected, the Night mode settings may be available, if the program material is encoded for Night mode, as shown in Figure 6.

Figure 6 The Night mode is a feature of Dolby Digital that uses special processing to preserve the dynamic range and full intelligibility of a movie soundtrack while reducing the peak level. This prevents abruptly loud transitions from disturbing others, without reducing the sonic impact of a digital source. The Night mode is only available when specially encoded Dolby Digital signals are played. To adjust the Night mode setting, make certain that the � cursor is on the NIGHT line of the DOLBY SURROUND submenu. Next, press the �/� Buttons o to choose between the following settings, as they appear in the on-screen display: OFF: When OFF is highlighted, the Night mode will not function. MID: When MID is highlighted, a mild compression will be applied. MAX: When MAX is highlighted, a more severe compression algorithm will be applied. We recommend that you select the MID setting as a starting point and change to the MAX setting later, if desired. The Night mode may also be adjusted directly any time a compatible Dolby Digital source is playing by pressing the Night Mode Button l. When the button is pressed, D-RANGE OFF will appear in the lower third of the video screen and in the Lower Display Line ı. Press the ¤ Button n within 3 seconds to select the desired setting. The last option line in this menu is the setting to turn the unit�s upsampling feature on or off. In normal use, this feature is turned off, which means that digital sources are processed at their native sample rate. For example, a 48kHz digital source will be processed at 48kHz. However, the AVR 240 allows you to upsample the incoming 48kHz signals to 96kHz for added resolution. To take advantage of this feature, press the ¤ Button n so that the � cursor is next to the UPSAMPLING line and press the �/� Buttons o that ON appears. Note that this feature is only available for the Dolby Pro Logic II-Music, Dolby Pro Logic II-Movie, Dolby Pro Logic and Dolby 3 Stereo modes.
Figure 5 When the cursor is at the MODE line, press the �/� Buttons o to select the desired Dolby Surround mode. If a Dolby Digital source is playing, the initial mode will automatically be selected, depending on the configuration of your system (e.g., 5.1 or 7.1) and the number of channels in the source being played, you may also select a combination mode that applies postprocessing so that Dolby Pro Logic IIx may be used to create back surround channels from a 2.0 or 5.1 source. This will appear in the MODE line by show-
