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, 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. Dolb y 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 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, unlik e
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.
4
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 y ou the best performance without
manual adjustment.
Manufactured under license from Dolb y 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
VIDEO SUPERIMPOSE
If you connect your video cassette recorder, video disc player ,
video monitor, etc. to this unit, y ou can take advantage of this unit’s
capability to display program titles , par ameter 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 o ver a blue colored background.
Additionally you can enjoy sound en vironment created by the
combination of Dolby Pro Logic and YAMAHA DSP.
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.

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 gener ate the sound field plus one center speak er
for dialog, when using Dolby Pro Logic Surround decoding. We
therefore recommend that you use a five-speaker setup. A fourspeaker system using only one pair of effect speak ers 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 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 , ho w e ver, are
obtained with the full system.
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.
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.
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.

Speakers and Speaker Placement
Main speaker Rear effect speaker Center speaker
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 abov e 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 vailable in some countries,
is an ideal choice for the center speaker.
