Congratulations!
You are the proud owner of a Yamaha Digital Sound Field Processing (DSP) System—an
extremely sophisticated audio component. The DSP system takes full advantage of Yamaha’s
undisputed leadership in the field of digital audio processing to bring you a whole new world
of listening experiences. Follow the instructions in this manual carefully when setting up your
system, and the DSP system will sonically transform your room into a wide range of listening
environments—anything from a famous concert hall to a cozy jazz club. In addition, you get
incredible realism from Dolby-Surround encoded video sources using the built-in Dolby Pro
Logic Surround Decoder.
Rather than tell you about the wonders of digital sound field processing, however, let’s get
right down to the business of setting up the system and trying out its many capabilities.
Please read this operation manual carefully and store it in a safe place for later reference.
1-1. GETTING STARTED

●
When you notice that remote control operation has become
erratic, or the distance from which the remote control will function
has decreased, it’s time to replace the batteries. Always replace
all batteries at the same time.
●
This remote control uses an advanced, highly directional infrared
beam. Be sure to aim the remote control directly at the remote
control sensor on the main unit when operating.
Remote control transmitter operation range
Notes
●
There should be no large obstacles between the remote
control transmitter and the main unit.
●
If the remote control sensor is directly illuminated by strong
lighting (especially an inverter type of fluorescent lamp etc.),
it might cause the remote control transmitter to work
incorrectly. In this case, reposition the main unit to avoid
direct lighting.
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. 5
through No. 14, and No. 16.
The YAMAHA “CINEMA DSP” logo indicates these programs
created by the combination of Dolby Pro Logic and YAMAHA DSP
technology.
VIDEO SUPERIMPOSE
If you connect your video cassette recorder, video disc player,
video monitor, etc. to this unit, you can take advantage of this unit’s
capability to display program titles, parameter data and information
about other various settings and adjustments on your video monitor’s
screen. This information will be superimposed over the video image.
If there is no video source connected or it is turned off, the
information will be displayed over a blue colored background.
NOTE: The program titles, parameter data and other information are
also displayed on the display panel of this unit.

Setting Up Your Speaker System
This unit has been designed to provide the best sound field
quality with a full five-speaker system setup, using one 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 five-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 five speaker system later.
Use of the Center Dialog Speaker Is Recommended
With digital sound field programs No. 5 through No. 16, 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 upgrade 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 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.
6
5 Speaker System
This is the recommended speaker
system, providing the best sound
effects.
With sound field programs No. 1
through No. 4, using effect speakers
reproduces the effective sound field.
With the sound field programs No. 5
through No. 16, the center speaker
provides precise center localization.
Center Mode—Set to NRML or WD.
(See page 22.)
4 Speaker System
Simple system without center
speaker.
With sound field programs No. 1
through No. 4, a sound effect matching
that of a 5-speaker system can be
obtained. With sound field programs No.
5 through No. 16, center sound is output
from the left and right main speakers.
Center Mode—Set to PHNTM.
(See page 22.)
Speakers and Speaker Placement
Your full five-speaker system will require two speaker pairs: the
MAIN SPEAKERS (your normal stereo 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 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.
Place the MAIN SPEAKERS in the normal position.
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.
NOTE: The Yamaha NS-C110 speaker, available in some countries,
is an ideal choice for the center speaker.

GENERAL INSTRUCTIONS FOR CONNECTIONS
Make sure that you have the left (L) and right (R) channels
correctly connected. That means that jacks marked “L” on this unit
must be connected to jacks marked “L” on other units. Likewise with
the “R” jacks. This is easy if you remember to always use the red
plug for the “R” jacks and the other plugs for the “L” jacks.
With speaker connections you must also be sure that the polarity
is correct. For each amplifier and each channel, connect the plus (+)
terminal of the amplifier to the plus terminal of the speaker, and
connect the minus (–) terminal of the amplifier to the minus terminal
of the speaker. To keep track of polarity, use a speaker cable that has
one of the two wires marked by a stripe or a different color.
