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, b ut chances are y ou’ll still notice
something missing, the acoustic environment of the live concert hall.
Extensive research into the e xact 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 an y one of these liv e performance
environments, all in your o wn home .

Dolby Pro Logic Surround

The Dolby Pro Logic Surround Decoder program lets y ou
experience the dramatic realism and impact of Dolby Surround mo vie
theater sound in your own home.Dolby Pro Logic gets its name from
its professional-grade steering logic circuitry, which provides greater
effective channel separ ation for a much higher degree of realism than
the “passive”Dolby Surround circuits f ound in today’s typical home
audio/video equipment.Dolby Pro Logic Surround provides a true
center channel, so that there are four independent channels, unlik e
passive Dolby Surround, which has in effect only three channels: left,
right, and rear.This center channel allows listeners seated in ev en
less-than-ideal positions to hear the dialog originating from the action
on the screen while experiencing good stereo imaging.

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.

Manufactured under license from Dolb y Laboratories Licensing
Corporation. Additionally licensed under one or more of the following
patents:U.S.number 3,950,590;Canadian numbers 1,004,603 and
1,037,877.“Dolby”, “Pro Logic”, and the doub le-D symbol are
trademarks of Dolby Laboratories Licensing Corporation.

Dolby Pro Logic Surround + DSP

You can also enjoy Dolb y Pro Logic with tw o modes of Digital
Sound Field Processing.These combinations expand the surround
effect of Dolby Pro Logic.One is the sound field program “Enhanced
DOLBY PRO LOGIC SURROUND”, which recreates the surround
effect of the 35 mm film movie theater.The other is the combination
of Dolby Pro Logic and the sound field program “MOVIE THEATER”,
which recreates the listening experience of a 70 mm film theater .

The Y AMAHA “CINEMA DSP” logo indicates these programs
created by the combination of Dolby Pro Logic and YAMAHA DSP
technology.

Directional Enhancement Circuit + DSP

The Y AMAHA directional enhancement (DIR.ENHANCEMENT)
circuit expands and f ocuses the digital sound field.

This effect puts you in the midst of the action, while centering and
focusing your attention to the screen.This circuit is availab le on
Sound Field programs “TV THEATER 1”, “TV THEATER 2”,
“CONCERT VIDEO”and “VIDEO THEA TER”.

Setting Up Your Speaker System

This unit has been designed to provide the best sound field
quality with a full sev en-speak er system setup, using two extra pairs
of effect speakers to gener ate the sound field plus one center
speaker for dialog, when using Dolb y Pro Logic Surround decoding.
We theref ore recommend that y ou 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 wa y to begin with this unit.You can
always upgr ade 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

With digital sound field programs No .7 through No. 12, by using
either the Directional Enhancement circuit or the Dolby Pro Logic
decoder, decoded signals will be output from the center channel.
Therefore, if y ou w ant to upgr ade the Audio/Video home theater
system, it is recommended to use the center speaker unit.

If for some reason it is not practical to use a center speak er, it is
possible to enjoy mo vie vie wing without it.Best results, however, are
obtained with the full system.

It is also possible to further expand your system with the addition
of a subwoofer and amplifier.You may wish to choose the
convenience of a Yamaha Active Servo Processing Subwoofer
System, which has its own built-in pow er amp.

Four Possible Types of Speaker System Configurations Recommended

7

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 12.)
Center Mode—Set to PHNTM.
(See page 25.)

5 Speaker System

Good for Audio/Video sources and
Dolby Pro Logic Surround.

With sound field programs No. 7
through No. 12, which utilize the center
speaker effect, more precise center
localization can be obtained.

FRONT MIX switch—Set to ON.
(See page 12.)
Center Mode—Set to NRML or WD.
(See page 25.)

6 Speaker System

Good for sound fields from 2-channel
stereo sources.

With sound field programs No. 1
through No. 6, 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 12.)
Center Mode—Set to PHNTM.
(See page 25.)

7 Speaker System

This is the recommended speaker
system, providing the best sound
effects.

With sound field programs No. 1
through No. 6, using both sets of effect
speakers (front and rear), reproduces
the most effective sound field. With the
sound field programs No. 7 through No.
12, the center speaker provides precise
center localization.

FRONT MIX switch—Set to OFF.
(See page 12.)
Center Mode—Set to NRML or WD.
(See page 25.)

Speakers and Speaker Placement

Your full sev en-speak er system will require three speaker pairs:
the MAIN SPEAKERS (your normal stereo speakers), the FRONT
EFFECT SPEAKERS, and the REAR EFFECT SPEAKERS, plus the
CENTER SPEAKER.You may also be using a subwoofer.

You will probably use your present stereo speakers as the MAIN
SPEAKER pair.The front effect, rear eff ect do not need to be equal
with the MAIN SPEAKERS, although the center speaker should be
as close as possible.They should have enough po w er handling
capacity to accept the maximum output of the DSP system or the
external amps that will drive them.

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 fe w feet behind and above
the MAIN SPEAKER pair.

Place the REAR EFFECT 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 interf erence , k eep the speak er abo ve 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 speak er is not so critical
because low bass tones are not highly directional.

NOTE:The Yamaha NS-C110 speaker, a v ailab le in some countries,
is an ideal choice for the center speaker.
