Programs No. 13 through No. 16 reproduces video discs, video tapes and similar sources which are Dolby Surround encoded and bear the
"DOLBY SURROUND" logo.
13. 70 mm MOVIE THEATER 1:
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
S.F.X., adventure movies, etc. with this program.
14. 70 mm MOVIE THEATER 2:
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.
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.

15. PRO LOGIC:
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.
16. PRO LOGIC 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: 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.
