AC3 RE-EQ
Normal Dynamic Range - This
mode engages the AC-3 “Line
Mode” coupled with the High Level
(HDR) and Low Level (LDR) reso-
lution factors preset to “255” or Full
On. While the option of Line Mode
is fixed, the HDR & LDR factors
can be scaled.
Maximum Dynamic Range - This
mode uses the AC-3 Line Mode
setting as found in AC3 Standard,
however the HDR and LDR fac-
tors are fixed at “0” or Full Off. For
play back of films, this mode may
be preferred over AC3 Ultra in that
some compression schemes are
designed to recreate the movie
theater environment in the home.
Minimum Dynamic Range - This
mode uses the AC-3 RF Mod
Mode setting. Also, the HDR and
LDR factors are fixed at “255” or
Full On. This mode is ideal when
viewing a film at a time were the
bangs may be too loud or the
softer sounds too low. In AC3
Night, the audio range is narrowed
between loud and soft sounds.
THX Processing - THX Process-
ing includes several enhance-
ments: Re-EQ, Timbre Matching,
and Adaptive Decorrelation.
These make the sound more like
the original film sound experience.
THX Re-Equalization Only - This
mode is used to provide partial
THX enhancements focused on
the adjustment of sound levels for
the front three channels. Typically,
films are mixed to standards which result in over bright sound in the
home. Re-EQ compensates for this factor in the home.
TRUE MONO Mode - When play-
ing AC-3, this mode will make a
mono center channel. Also, when
playing PCM, this mode will make
a mono center channel.
