spaciousness and envelopment through the surround speakers.
This enhancement is most noticeable when the surround speakers
are positioned to the side of the primary listening position, or when
the primary listening position is located against the rear wall. The
effectiveness of...

MID RT parameter setting for more natural effects in smaller
listening spaces.

versions of the selected listening mode. When PRESET is selected,
the listening mode is heard in its factory-default condition – as if all
parameters had been restored to their factory-default settings. No
parameter settings are affected when this option is selected. The
listening mode will revert to its modified...

Controls the output level of LFE information – the .1 channel in a
5.1- or 6.1-channel input source – that is sent to the Main Zone
audio output labeled Subwoofer. Low frequencies from up to seven
other channels might be combined with the LFE information to
create the subwoofer output signal, which significantly increases
subwooferoutput levels. Careful adjustment...

PANORAMAON, OFF
When set to ON, extends the front stereo image to include 
surround channel signals, which creates a “wraparound” effect
with side wall imaging.
Note:
The DOLBY PLII MUSIC listening mode PANORAMA
parameter should not be confused with the separate
PANORAMA listening mode (5-11).
PRE-DELAYOFF, 1 to 100ms
Adjusts delay time between the direct sound and the onset of
reverberation. Higher settings make the simulated space sound
larger. Because some pre-delay is inherent...

SPEECH DETECTON, OFF
Distinguishes monaural speech from other input sources. When set
to ON, effects are lowered to minimize interference and unnatural
echo in monaural speech. When stereo input sources are
present, the front left and right channels are independently used as
inputs for ambience synthesis. When strong monaural speech is
present in the input source, the monaural component of the
ambience effect is reduced and the stereo component of the effect
is increased. When set...
