PROLOGIC/Normal
(When the Dolby Pro Logic Surround is decoded):
AC-3/Normal
(When the Dolby Surround AC-3 is decoded):
The built-in Dolby Pro Logic Surround
decoder or Dolby Surround AC-3 decoder
precisely reproduces sounds and sound
effects of a source encoded with Dolby
Surround. The realization of a highly
efficient decoding process improves
crosstalk and channel separation and
makes sound positioning smoother and
more precise.
PROLOGIC/Enhanced
(When the Dolby Pro Logic Surround is decoded):
AC-3/Enhanced
(When the Dolby Surround AC-3 is decoded):
This program ideally simulates the multi-
surround speaker systems of the 35 mm
film theater. The Dolby Surround decoding
and the digital sound field processing is
precisely performed without altering the
originally designed sound orientation. The
surround effects produced by this sound
field folds the viewer naturally from the rear
to the left and right and toward the screen.
NOTE: The Dolby Surround system is designed to be used with
program material (mainly videotaped movie soundtracks) encoded
with the Dolby Surround.
NOTE: If the main and center channel sound is considerably altered
by overadjustment of the BASS or TREBLE controls, the relationship
with the rear channels may produce an unnatural effect.
12.DOLBY SURROUND
Reproduces video discs, video tapes and similar sources which are Dolby Surround encoded and bear the “DOLBY SURROUND” logo.
