FEATURES
This unit is a sophisticated digital sound processor designed
specifically for decoding the Dolby Digital (AC-3).
This unit consists of a Dolby Digital (AC-3) Decoder, Yamaha
Digital Sound Field Processor and other original Yamaha functions
developed using the newest technology to reproduce sources
encoded with the Dolby Digital (AC-3) precisely as movie sound
creators intended.This unit will lead listeners into a totally new
sound experience.
This unit is equipped with “6-channel discrete”output terminals
for sending multi-channel audio signals of the Dolby Digital (AC-3)
individually.Therefore, the audio amplifier or receiver must have
“discrete” input terminals to receive the signals from this unit.
If your amplifier or receiver can input 5-channel discrete signals
only, see page 12.
Digital Sound Field Processing
This unit incorporates a sophisticated digital sound field
processor.The processor allows you to electronically expand and
change the shape of the audio sound field from audio and video
sources, creating a theater-like experience in your listening room.
Dolby Digital (AC-3)
The built-in Dolby Digital (AC-3) Decoder leads you into a
totally new sound experiences.
Dolby Digital (AC-3) is a new generation of multi-channel digital
audio technology, or the newest spatial sound processing format
developed for 35 mm film-movies by employing a new kind of low
bit-rate audio coding.
Dolby Digital (AC-3) is a digital surround sound system that
provides completely independent multi-channel audio to
consumers.In multi-channel form, Dolby Digital (AC-3) provides
five full range channels in what is sometimes referred to as a “3/2”
configuration: three front channels (left, center and right), plus two
surround channels.A sixth bass-only effect channel is also
provided for output of LFE (low frequency effect), or low bass
effects that are independent of other channels.This channel is
counted as 0.1, thus giving rise to the term 5.1 channels in total.
Compared to Dolby Pro Logic that is referred to a “3/1” system
(left front, center, right front and just one surround channel), Dolby
Digital (AC-3) features two surround channels, called stereo or
split surrounds, each offering the same full range fidelity as the
three front channels.
English
Sound of wide dynamic range reproduced by the five full range
channels presents listeners much excitement that has never been
experienced before. Precise sound orientation by the discrete
digital sound processing expands realism that the original movie
possesses.

Laser Disc is a home audio format that could benefit from
CINEMA DSP
Dolby Digital (AC-3).In the near future, Dolby Digital (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 Dolby Digital (AC-3) encoded
video software.

The following original functions make the surround-sound effect
of Dolby Digital (AC-3) become the most suitable for your audio
system and the listening conditions.
Dolby Digital (AC-3) + DSP (CINEMA DSP)
Dolby Digital (AC-3) 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 Digital (AC-3) decoded sound field.
● 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 output terminals or SUBWOOFER output
terminal to maximize system performance.
● Output of LFE can be assigned to either the MAIN output
terminals or SUBWOOFER output terminal to maximize
system performance.

The YAMAHA “CINEMA DSP” logo indicates those programs
are created by the combination of Dolby Surround and YAMAHA
DSP technology.
Dolby Digital (AC-3) + 2 Digital Sound Fields
Dolby Digital (AC-3) + 3 Digital Sound Fields
English
Digital sound fields are created on the independent left and
right surround sides of the Dolby Digital (AC-3) decoded sound
field respectively.They create a wide acoustic environment and
emphasize surround-effect in the room, letting you feel much
presence as if you are watching a movie in a popular Dolby Stereo
Digital theater.
This combination is available on the sound field program
“ DIGITAL ENHANCED”.
Digital sound fields are created on the presence side and the
independent left and right surround sides of the Dolby Digital (AC-
3) decoded sound field respectively.They create a wide acoustic
environment and much surround effect in the room without losing
high channel separation.With wide dynamic range of Dolby Digital
(AC-3) 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 on the sound field program
“DIGITAL MOVIE THEATER”.
