The following original functions make the surround-sound effect
of Dolby Digital become the most suitable for your audio
system and the listening conditions.
CINEMA DSP: Dolby Surround + DSP
The Dolby Surround sound system shows its full ability in a
large movie theater, because movie sounds are originally
designed to be reproduced in a large movie theater using many
speakers. It is difficult to create a sound environment similar to
that of a movie theater in your listening room, because the
room size, materials of inside walls, the number of speakers,
etc. of your listening room are very different from those of a
movie theater. YAMAHA DSP technology made it possible to present you with
nearly the same sound experience as that of a large movie
theater in your listening room by compensating for the lack of
presence and dynamics in your listening room with its original
digital sound fields combined with the Dolby Surround sound
system.
CINEMA DSP
The YAMAHA “CINEMA DSP” logo indicates those programs
that are created by the combination of Dolby Surround and
YAMAHA DSP technology.
Dolby Pro Logic + 2 Digital Sound Fields
Digital sound fields are created on the presence side and the
rear surround side of the Dolby Pro Logic Surround-decoded
sound field, respectively. They create a wide acoustic
environment and emphasize the surround effect in the room,
letting you feel as much presence as if you are watching a
movie in a popular Dolby Stereo theater.
This combination is available when the DOLBY PRO LOGIC
ENHANCED/DOLBY DIGITAL ENHANCED, 70 mm MOVIE
THEATER/DIGITAL MOVIE THEATER or TV SPORTS sound
field program is selected, and the input signal of source is
analog, PCM audio or encoded with Dolby Digital sound in
2-channel.
Dolby Digital + 3 Digital Sound Fields
Digital sound fields are created on the presence side and the
independent left and right surround sides of the Dolby Digital-
decoded sound field, respectively. They create a wide
acoustic environment and strong surround effect in the room
without losing high-channel separation. With the wide
dynamic range of Dolby Digital sound, this sound field
combination lets you feel as if you are watching a movie in the
newest Dolby Stereo Digital theater. This will be the most
ideal home theater sound at the present time.
This combination is available when the DOLBY PRO LOGIC
ENHANCED/DOLBY DIGITAL ENHANCED, 70 mm MOVIE
THEATER/DIGITAL MOVIE THEATER or TV SPORTS sound
field program is selected, and the input signal of source is
encoded with Dolby Digital sound (except in 2-channel).
