Laser Disc is a home audio format that could benefit from
Dolby AC-3. In the near future, Dolby AC-3 will also be applied to
DBS, CATV, DVD and HDTV. The ongoing release of Dolby Stereo
Digital theatrical films now underway will provide an immediate
source of AC-3 encoded video software.

The following original functions make the surround-sound effect
of Dolby Surround AC-3 become the most suitable for your audio
system and the listening conditions.
• Dynamic range (sound scale) of source can be changed so
that it will be suitable for the listening conditions.
• Output of low bass from any channel can be assigned to
either the MAIN SPEAKERS terminals or SUBWOOFER
terminals to maximize system performance.
• Output of LFE can be assigned to either the MAIN
SPEAKERS terminals or SUBWOOFER terminals to
maximize system performance.
Dolby Surround + DSP (CINEMA DSP)
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 is
much 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 lack of presence and
dynamics in your listening room with its original digital sound fields
combined with Dolby Surround sound field.
