This unit incorporates a sophisticated, multi-program digital
sound field processor. The processor allows you to electronically
expand and change the shape of the audio sound field from both
audio and video sources, creating a theater-like experience in your
listening room. This unit has a total of 10 digital sound field
processor (DSP) modes. You can create an excellent audio sound
field by selecting a suitable sound field (this will, of course, depend
on what you will be listening to), and adding desired adjustments.
In addition, this unit incorporates a Dolby Pro Logic Surround
decoder and Dolby Digital (AC-3) decoder for multi-channel sound
reproduction of Dolby Surround encoded video sources. The
operation of the Dolby Pro Logic Surround or Dolby Digital (AC-3)
decoder can be controlled by selecting a corresponding DSP
program including combined operations of the Yamaha DSP and
the Dolby Pro Logic Surround or Dolby Digital (AC-3) decoder.
Digital Sound Field Processing
What is it that makes live music so good? Today’s advanced
sound reproduction technology lets you get extremely close to the
sound of a live performance, but chances are you’ll still notice
something missing, the acoustic environment of the live concert
hall. Extensive research into the exact nature of the sonic
reflections that create the ambience of a large hall has made it
possible for Yamaha engineers to bring you this same sound in
your own listening room, so you’ll feel all the sound of a live
concert. What’s more, our technicians, armed with sophisticated
measuring equipment, have even made it possible to capture the
acoustics of a variety of actual concert halls, jazz clubs, theaters,
etc. from around the world, to allow you to accurately recreate any
one of these live performance environments, all in your own home.

Dolby Pro Logic Surround
This unit employs a Dolby Pro Logic Surround decoder similar
to professional Dolby Stereo decoders used in many movie
theaters. By using the Dolby Pro Logic Surround decoder, you can
experience the dramatic realism and impact of Dolby Surround
movie theater sound in your own home. Dolby Pro Logic employs a
four channel five speaker system. The Pro Logic Surround system
divides the input signal into four levels: the left and right main
channels, the center channel (used for dialog), and the rear
surround sound channels (used for sound effects, background
noise, and other ambient noises). The center channel allows
listeners seated in even less-than-ideal positions to hear the dialog
originating from the action on the screen while experiencing good
stereo imaging. Dolby Surround is encoded on the sound track of
pre-recorded video tapes, laser discs, and some TV/cable
broadcasts. When you play a source encoded with Dolby Surround
on this unit, the Dolby Pro Logic Surround decoder decodes the
signal and distributes the surround-sound effects.
This Dolby Pro Logic Surround Decoder employs a digital
signal processing system. This system improves the stability of
sound at each channel and crosstalk between channels, so that
positioning of sounds around the room is more accurate compared
with conventional analog signal processing systems.
In addition, this unit features a built-in automatic input balance
control. This always assures you the best performance without
manual adjustment.
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.
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.

English
Laser Disc is a home audio format that could benefit from
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.
● 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.
The YAMAHA “CINEMA DSP” logo indicates those programs
are created by the combination of Dolby Surround and YAMAHA
DSP technology.
CINEMA DSP

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 surround-effect in the room, letting you feel much
presence as if you are watching a movie in a popular Dolby Stereo
theater.
This combination is available when the sound field program No.
2, No. 3 or No. 4 is selected, and the input signal of source is
analog, PCM audio or encoded with the Dolby Digital (AC-3) in 2-
channels.
Dolby Digital (AC-3) + 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 (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 when the sound field program No.
2, No. 3 or No. 4 is selected, and the input signal of source is
encoded with the Dolby Digital (AC-3) (except in 2-channels).

Setting Up Your Speaker System
This unit has been designed to provide the best sound field
quality with a full seven-speaker system setup, using two extra
pairs of effect speakers to generate the sound field plus one center
speaker for dialog. We therefore recommend that you use a seven-
speaker setup. A four-speaker system using only one pair of effect
speakers for the sound field will still provide impressive ambience
and effects, however, and may be a good way to begin with this
unit. You can always upgrade to the full seven speaker system
later. In the 4 or 5 speaker system, the Digital Sound Field
Processing is still performed, but the main speakers are used for
both the main channels and the front effect channels.
Use of the Center Dialog Speaker Is Recommended
When playing back a source with the DSP programs No. 1
through No. 4, or when the Dolby Digital (AC-3) is decoded with
any DSP program used, if the source contains center-channel
signals, dialog, vocals etc. are output from the center channel.
Therefore, if you want to maximize the performance of your
Audio/Video home theater system, it is recommended that you use
a center channel speaker.
If for some reason it is not practical to use a center speaker, it
is possible to enjoy movie viewing without it. Best results, however,
are obtained with the full system.
Use of a Subwoofer Expands Your Sound Field
It is also possible to further expand your system with the
addition of a subwoofer and amplifier. The use of a subwoofer is
effective not only for reinforcing bass frequencies from any or all
channels, but also for reproducing the LFE (low frequency effect)
sound with high fidelity when playing back a source with the Dolby
Digital (AC-3) decoded. You may wish to choose the convenience
of a Yamaha Active Servo Processing Subwoofer System, which
has its own built-in power amplifier.
SPEAKER SETUP

English
4 Speaker System
Simplest system.
You can enjoy widely diffused sound
by only adding two additional speaker
units at the rear.
FRONT MIX switch—Set to ON.
(See page 20.)
CENTER SPEAKER—Set to PHNTM.
(See page 30.)
5 Speaker System
Good for Audio/Video sources.
By the use of center speaker, center
sounds (dialog, vocals etc.) are
precisely localized.
FRONT MIX switch—Set to ON.
(See page 20.)
CENTER SPEAKER—Set to NRML
or WIDE. (See page 30.)
6 Speaker System
Good for sound fields from 2-
channel stereo sources.
When a normal stereo source is
played back with the sound field
programs No. 5 through No. 10, a
sound effect matching that of a 7-
speaker system can be obtained. The
addition of front left and right effect
speakers produces a more effective
sound field.
FRONT MIX switch—Set to OFF.
(See page 20.)
CENTER SPEAKER—Set to PHNTM.
(See page 30.)
7 Speaker System
This is the recommended speaker
system, providing the best sound
effects.
When a normal stereo source is
played back with the sound field
programs No. 5 through No. 10, using
both sets of effect speakers (front and
rear), reproduces the most effective
sound field. When using the sound
field programs No. 1 through No. 4 or
when using any program with the
Dolby Digital (AC-3) decoded, the
center speaker provides precise center
localization.
FRONT MIX switch—Set to OFF.
(See page 20.)
CENTER SPEAKER—Set to NRML
or WIDE. (See page 30.)
Four Possible Types of Speaker System Configurations Recommended
12
Speakers and Speaker Placement
Your full seven-speaker system will require three speaker pairs:
the MAIN SPEAKERS (your normal stereo speakers), the FRONT
EFFECT SPEAKERS and the REAR SPEAKERS, plus the
CENTER SPEAKER. You may also be using a subwoofer.
The MAIN SPEAKERS should be high performance models
and have enough power handling capacity to accept the maximum
output of your audio system.
Other speakers do not have to be equal to the MAIN
SPEAKERS. For precise sound localization, however, it is ideal to
use high performance models that can reproduce sounds in full
range for the CENTER SPEAKER and the FRONT EFFECT and
REAR SPEAKERS.
Place the MAIN SPEAKERS in the normal position.
Place the FRONT EFFECT SPEAKERS further apart than the
MAIN SPEAKERS, on either side of and a few feet behind and
above the MAIN SPEAKER pair.
Place the REAR SPEAKERS behind your listening position.
They should be nearly six feet up from the floor.
Place the CENTER SPEAKER precisely between the two MAIN
SPEAKERS. (To avoid interference, keep the speaker above or
below the television monitor, or use a magnetically shielded
speaker.)
If using a SUBWOOFER, such as a Yamaha Active Servo
Subwoofer System, the position of the speaker is not so critical
because low bass tones are not highly directional.
