11. MOVIE THEATER
Ideal for reproducing video discs, video tapes and similar sources
which are Dolby Surround encoded and bear the “DOLBY
SURROUND” logo.
70 mm Adventure: This program is ideal for precisely
reproducing the sound design of the
newest movies. The sound field is made
according to the design of the newest
movie theaters, so the reverberations of
the sound field itself are restrained as
much as possible. The three dimensional
feeling of the sound field is emphasized,
and dialog is precisely oriented on the
screen. You can enjoy watching Sci-Fi,
adventure movies, etc. with this program.
70 mm General: This program is for reproducing sounds on
a 70 mm multi-track film, and characterized
by a soft and extensive sound field. The
front presence side of the sound field is
relatively narrow. It spatially spreads all
around and toward the screen, restraining
echo effect of conversations without losing
clarity. For the surround side, the data of
the sound field of an opera house is used
on an enlarged scale, so the harmony of
music or chorus sounds beautifully in a
wide space at the rear of the sound field.
12. DOLBY PRO LOGIC SURROUND
Reproduces video discs, video tapes and similar sources which
are Dolby Surround encoded and bear the “DOLBY
SURROUND” logo.
Normal: The digital Dolby Pro Logic decoder
reproduces sounds and sound effects of a
source encoded in Dolby Surround. The
realization of a highly efficient decoding
process improves crosstalk and channel
separation and makes sound positioning
smoother and more precise.
Enhanced: This program ideally simulates the multi-
surround speaker systems of the 35 mm
film theater. Surround signals by the Dolby
Pro Logic decoder are processed on the
surround side of the sound field based on
the data of the sound field of a shoe-box
hall. 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 Pro Logic Surround system is designed to be used
with program material (mainly videotaped movie soundtracks)
encoded with the Dolby Surround system.
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.
