When the AVR21EN is configured for 7.1-channel operation, and the SURR BACK line of the
SPEAKER SETUP menu is set to SMALL or LARGE, additional modes such as Dolby Digital EX,
Dolby Pro Logic IIx and DTS-ES will appear, as they are only available when seven main
speakers are present. In addition, some of the modes available in the AVR21EN will not appear
unless a digital source is selected and is playing the correct bitstream.
To select the mode that will be used as the initial default for an input, first press the ▼/▲
Navigation Button [oval 16] until the cursor is next to AUDIO MODE. Press the ◄/► Navigation
Button [oval 16] to select a master category name, such as DOLBY, DTS, DSP (SURR). Next,
press the ▼/▲ Navigation Button [oval 16] to move the on screen cursor next to A.TYPE.
Press the ◄/► Navigation Button [oval 16] to scroll through the available choices.
The following paragraphs detail the instructions needed for modes with multiple choices.
DOLBY
The Dolby Surround choices include Dolby Digital, Dolby Pro Logic II, Dolby Pro Logic IIx, Movie
and Music, Dolby Pro Logic and Dolby Virtual Speaker Reference or Wide. For a complete
description of the different Dolby Surround modes, see section: Main Room
Operation/Surround Mode Selection. The Dolby Digital EX and Dolby Pro Logic IIx modes are
only available when the system is set for 7.1 operation by configuring the Surround Back
speakers to “Small” or “Large” as described in section: AVR21EN Configuration/Speaker Setup.
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 described in: Main Room
Operation/Surround Mode Selection.
When the cursor is pointing to the AUDIO MODE line, press the ◄/► Navigation Buttons [oval
16] to select the desired Dolby surround mode, again remembering that the choice of available
modes will vary with the type of program material being played and the number of speakers in
your system configuration.
When the DOLBY DIGITAL mode is selected, there are additional settings available for Night
Mode.
Night Mode is a feature of Dolby Digital that preserves 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. Night Mode is only
available when specially encoded Dolby Digital signals are played. To adjust the Night Mode
setting, make certain that the on-screen cursor is on the NIGHT MODE line with DOLBY selected
in AUDIO MODE. Next, press ◄/► Navigation Button [oval 16] to choose between the following
settings, as they appear in the on-screen display:
OFF: When OFF is shown, Night Mode will not function.
MEDIUM: When MEDIUM is shown, a mild compression will be applied.
MAXIMUM: When MAXIMUM is shown, a more severe compression algorithm will be applied.
We recommend that you select the medium setting as a starting point and change to the
maximum setting later, if desired.
Night Mode may also be adjusted directly any time a Dolby Digital source is playing by first
pressing the AVR Button [oval 5] and then pressing the Night Button [oval 34] on the remote.
When the Night Button is pressed, Night Mode Status (OFF, MED, MAX) will appear in the lower
third of the video screen and in the AVR Lower Display Line [square 34]. Press the Night
Button [oval 34] within three seconds to select the desired setting.
