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
The Dolby Pro Logic Surround Decoder program lets you
experience the dramatic realism and impact of Dolby Surround movie
theater sound in your own home.Dolby Pro Logic gets its name from
its professional-grade steering logic circuitry, which provides greater
effective channel separation for a much higher degree of realism than
the “passive” Dolby Surround circuits found in today’s typical home
audio/video equipment.Dolby Pro Logic Surround provides a true
center channel, so that there are four independent channels, unlike
passive Dolby Surround, which has in effect only three channels:left,
right, and rear.This 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.
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 Dolby Laboratories Licensing
Corporation.Additionally licensed under Canadian patent number
1,037,877.“Dolby”, “Pro Logic”, and the double-D symbol are
trademarks of Dolby Laboratories Licensing Corporation.
Dolby Pro Logic Surround + DSP
Additionally you can enjoy sound environment created by the
combination of Dolby Pro Logic and YAMAHA DSP.
Precise sound
movement and orientation by the Dolby Pro Logic technology is
added to sound fields which are precisely recreated on the
basis of actual acoustic environments by the DSP technology,
so it is suitable for any Audio/Video source with video image.
This combination is used on sound field programs No. 8 through
No.11, and “Enhanced DOLBY PRO LOGIC” of No.12.
The YAMAHA “CINEMA DSP”logo indicates these programs are
created by the combination of Dolby Pro Logic and YAMAHA DSP
technology.

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, when using Dolby Pro Logic Surround decoding.
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
With digital sound field programs No.8 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 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.
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 power amp.
8
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 13.)
Center Mode—Set to PHNTM.
(See page 26.)
5 Speaker System
Good for Audio/Video sources and
Dolby Pro Logic Surround.
With sound field programs No. 8
through No. 12, which utilize the center
speaker effect, more precise center
localization can be obtained.
FRONT MIX switch—Set to ON.
(See page 13.)
Center Mode—Set to NRML or WD.
(See page 26.)
6 Speaker System
Good for sound fields from 2-channel
stereo sources.
With sound field programs No. 1
through No. 7, 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 13.)
Center Mode—Set to PHNTM.
(See page 26.)
7 Speaker System
This is the recommended speaker
system, providing the best sound
effects.
With sound field programs No. 1
through No. 7, using both sets of effect
speakers (front and rear), reproduces
the most effective sound field. With the
sound field programs No. 8 through No.
12, the center speaker provides precise
center localization.
FRONT MIX switch—Set to OFF.
(See page 13.)
Center Mode—Set to NRML or WD.
(See page 26.)
Four Possible Types of Speaker System Configurations Recommended

English
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 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 and rear effect do not need to be
equal with the MAIN SPEAKERS, although the center speaker
should be as close as possible.They should have enough power
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 few 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 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.
