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.
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.
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.

Dolby Pro Logic Surround
Within approximately
7 m (23 feet)
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.
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.

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.
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.
In addition, this unit features a built-in automatic input balance
control. This always assures you the best performance without
manual adjustment.
If there is no video source connected or it is turned off, the
information will be displayed over a blue colored background.

Setting Up Your Speaker System
5 Speaker System
4 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
This is the recommended speaker
system, providing the best sound
effects.
Simple system without center
speaker.
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.
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.
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.
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.
Center Mode—Set to NRML or WD.
(See page 22.)
Center Mode—Set to PHNTM.

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.)
Main speaker
Rear effect speaker Center 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
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.
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.

2-7. DESCRIPTIONS OF THE SOUND FIELD PROGRAMS
The following list gives brief descriptions of the sound fields produced by each of the DSP programs. Keep in mind that most of these are
precise digital recreations of actual acoustic environments. The data for them was recorded at the locations described using sophisticated sound
field measurement equipment.
* The channel level balance between the left rear effect speaker and the right rear effect speaker may vary depending on the sound
field you are listening to. This is due to the fact that most of these sound field recreations are actual acoustic environments.
1. CONCERT HALL:
3. JAZZ CLUB:
A large round concert hall with a rich surround effect.
Pronounced reflections from all directions emphasize the
extension of sounds. You will experience the sound field with a
great deal of presence sitting at about the center position near
the stage.
A jazz club in New York. It is in a basement and has a relatively
spacious floor area. The reflection pattern is similar to that of a
small hall.
This sound field is also effective for karaoke. This is because
you feel as if you are standing on a real stage.
2. CHURCH:
4. ROCK CONCERT:
A church in Tokyo shaped like a cross. There is the altar at the
upper side of the “cross”, and a pipe organ at the opposite side
(the lower side of the cross). It is a very unique shape with
walls all leaning inside, and pillars standing by the side of walls
only. The sound field has moderate reverberations of which
time is 2.5 seconds.
The ideal program for lively, dynamic rock music. The data for
this program was recorded at LA’s “hottest” rock club.

5. CONCERT VIDEO:
7. CLASSIC FILM:
This program produces an enthusiastic atmosphere and lets you
feel that you are in the midst of the action, as if attending an
actual jazz or rock concert.
The indirect sound constituent spreads on the surround side of
the sound field by the use of data of a large round hall for the
surround side, so the image space around the screen and the
sound space are fully expanded.
This program is for reproducing monaural video sources (old
movies etc.). Monaural sounds are reproduced with much
presence by the front presence side of the sound field and
optimum reverberation effect. The use of the center speaker
makes conversations more audible, obtaining a pleasant mix of
conversations and picture.
6. OPERA:
8. ANIMATION:
This program provides excellent depth of vocals and overall
clarity, restraining excessive reverberation.
Powerful reverberations on the front presence side of the sound
field adds depth to the image, so expanding the image space. On
the rear surround side, sounds are reproduced lightly but vividly.
The sound field of this program matches image effects of
animated films regardless of the genre. Conversations, sounds
and sound effects are reproduced with vitality by this program. A
source in stereo will obtain more effect, letting you steep yourself
in a fantastic world of animations.
For opera, the orchestra pit and the stage are ideally combined,
letting you feel a full presence sound. The rear surround side of
the sound field is relatively moderated, however, it reproduces
beautiful sound by the use of the data of a concert hall. You will
not be tired from long watching of an opera.

11.GAME:
The sound field of a disco is used for the front presence side, and
The data of the sound field of a relatively narrow space is used for
the front presence side. A moderately sized spatial sound field
without excessive sound extension and reverberations gives
reality to the characters in a drama.
The data of the sound field of an opera house is used for the rear
surround side. In a stereo program, background music is
reproduced more beautifully with much depth, enhancing sound
effects on the drama. It’s natural sound effect will not make you
tired from long watching.
the sound field of a concert hall in Vienna is used for the rear
surround side.
This program reproduces video game music etc. more vividly
emphasizing the fast tempo and lightness of the music. If the
music is in stereo, more effective sound field will be gained by this
program.
This program is also suitable for karaoke popular music.
10.TV SPORTS:
12.KARAOKE:
Though the front presence side of the sound field is relatively
narrow, the rear surround side employs the sound environment of
a large concert hall. With this program, you can enjoy watching
various TV programs such as the news, variety shows, music
programs or sports programs. In a stereo broadcast of a sports
game, the commentator is oriented at the center position, and the
shouts and the atmosphere in the stadium spreads on the
surround side, however, spreading of them to the rear side is
properly restrained.
Vocals are reproduced with gentle reverberations on the stage
surrounded by seats in a round hall. A feeling of echo from the
high ceiling and reverberations in front and behind the hall brings
a lot of presence on both the stage and the seats. By using a
source with digital sound, the sound of the greatly instrumental
accompaniment is much expanded, so emphasizing the spatial
effect with vocals. You feel as if you are standing on a live-stage.

13.70 mm MOVIE THEATER 1:
15.PRO LOGIC:
This program is ideal for precisely reproducing the sound design
of the newest movies. The sound field is made according to the
design of the newest movie theaters, so the reverberations of the
sound field itself are restrained as much as possible. The three
dimensional feeling of the sound field is emphasized, and dialog
is precisely oriented on the screen. You can enjoy watching
S.F.X., adventure movies, etc. with this program.
The digital Dolby Pro Logic decoder reproduces sounds and
sound effects of a source encoded in Dolby Surround. The
realization of a highly efficient decoding process improves
crosstalk and channel separation and makes sound positioning
smoother and more precise.
14.70 mm MOVIE THEATER 2:
16.PRO LOGIC ENHANCED:
This program is for reproducing sounds on a 70 mm multi-track
film, and characterized by a soft and extensive sound field. The
front presence side of the sound field is relatively narrow. It
spatially spreads all around and toward the screen, restraining
echo effect of conversations without losing clarity. For the
surround side, the data of the sound field of an opera house is
used on an enlarged scale, so the harmony of music or chorus
sounds beautifully in a wide space at the rear of the sound field.
This program ideally simulates the multi-surround speaker
systems of the 35 mm film theater. Surround signals by the Dolby
Pro Logic decoder are processed on the surround side of the
sound field based on the data of the sound field of a shoe-box
hall. The surround effects produced by this sound field folds the
viewer naturally from the rear to the left and right and toward the
screen.
NOTE: The Dolby Pro Logic Surround system is designed to be
used with program material (mainly videotaped movie soundtracks)
encoded with the Dolby Surround system.
NOTE: If the main and center channel sound is considerably
altered by overadjustment of the BASS or TREBLE controls, the
relationship with the rear channels may produce an unnatural
effect.

CREATING YOUR OWN SOUND FIELDS
3-1. SELECTING AND EDITING PROGRAM PARAMETERS
(2) Reverberations. These are caused by reflections from more than
one surface—walls, ceiling, the back of the room—so numerous that
they merge together to form a continuous sonic “afterglow”. They are
non-directional, and lessen the clarity of the direct sound.
WHAT IS A SOUND FIELD?
In order to explain the impressive functions of the DSP system,
we need to first understand what a sound field really is.
Direct sound, early reflections and subsequent reverberation
taken together help us to determine the subjective size and shape of
the room, and it is this information that the DSP system reproduces
in order to create sound fields.
What really creates the rich, full tones of a live instrument are the
multiple reflections from the walls of the room. In addition to making
the sound “live”, these reflections enable us to tell where the player is
situated, and the size and shape of the room in which we are sitting.
We can even tell whether it is highly reflective, with steel and glass
surfaces, or more absorbent—wood panels, carpeting and curtains.
If you could create the appropriate early reflections and
subsequent reverberations in your listening room, you would be able
to create your own listening environment. The acoustics in your room
could be changed to those of a concert hall, a dance floor, or virtually
any size room at all. This ability to create sound fields at will is
exactly what Yamaha has done with the DSP system.
THE ELEMENTS OF A SOUND FIELD
In any environment, in addition to the direct sound coming
straight to our ears from the player’s instrument, there are two distinct
types of sound reflections that combine to make up the sound field:
DSP programs consist of some parameters to determine
apparent room size, reverberation time, distance from you to the
performer, etc. In each program, those parameters are preset with
values precisely calculated by Yamaha to create the sound field
unique for the program. It is recommended to use DSP programs
without changing values of parameters, however, this unit also allows
you to create your own sound fields. Starting with one of the built-in
programs, you can adjust those parameters. Even if power is turned
off, your custom sound fields will remain in the DSP system’s
memory for about two weeks. The following pages detail how to
make your own sound fields.
(1) Early Reflections. Reflected sounds reach our ears extremely
rapidly (50 ms — 100 ms after the direct sound), after reflecting from
one surface only—for example, from the ceiling or a wall. These
reflections fall into specific patterns as shown in the diagram on page
35 for any particular environment, and provide vital information to our
ears. Early reflections actually add clarity to the direct sound.
33
Download from Www.Somanuals.com. All Manuals Search And Download.
Each sound field program has a set of parameters that allow you
to change the characteristics of the acoustic environment to create
precisely the effect you want. These parameters correspond to the
many natural acoustic factors that create the sound field you
experience in an actual concert hall or other listening environment.
The size of the room, for example, affects the length of time between
the “early reflections”—that is, the first few widely spaced reflections
you hear after the direct sound. The “ROOM SIZE” parameter
provided in many of the DSP programs alters the timing between
these reflections, thus changing the shape of the “room” you hear. In
addition to room size, the shape of the room and the characteristics
of its surfaces have a significant effect on the final sound. Surfaces
that absorb sound, for example, cause the reflections and
reverberations to die out quicker, while highly reflective surfaces allow
the reflections to carry on for a longer period of time. The DSP
parameters allow you to control these and many other factors that
contribute to your personal sound field, allowing you to essentially
“redesign” the concert halls and rooms provided to create custom-
tailored listening environments that ideally match your mood and
music.
2. When the desired parameter has been recalled, use the SET
MENU/PARAMETER + (increment) and – (decrement) keys to
change its value to create the effect you want. + increases the value
of the selected parameter, and – decreases the value of the selected
parameter. In both cases you can hold the key down for continuous
incrementing or decrementing. The display will pause for a moment
at the initial value of the parameter as a reminder. (On the monitor
screen, mark at the head of parameter name disappears at the
*
initial value of the parameter.)
NOTE: Parameter edits made in this way will remain in effect even
with power cut due to power failure or the power plug disconnected
from the AC outlet for up to about two weeks, after which all
parameters, as well as other adjustments or settings on this unit, will
return to their initial values or conditions.
Refer to “3-2. DESCRIPTIONS OF THE DIGITAL SOUND FIELD
PARAMETERS” on page 35 for a description of what each
parameter does, how it effects the sound, and its control range.
1. With the desired program selected, press the SET MENU/
PARAMETER Select (▼) key on the remote control unit once. This
will recall the first parameter. In the case of the CONCERT HALL
program, for example, this would be the INIT. DLY parameter. You
can continue pressing the SET MENU/PARAMETER Select (▼) key
to select other parameters in sequence. If the key is pressed when
the last parameter is being displayed, the first parameter is selected
again.

INIT DLY (Initial Delay)
ROOM SIZE
How it Affects the Sound:
How it Affects the Sound:
Changes the apparent distance from the source sound.
Changes the apparent size of the music venue. The larger the
value, the larger the simulated room will sound.
Since the distance between a sound source and a reflective
surface determines the delay between the direct sound and the first
reflection, this parameter changes the location of the sound source
within the acoustic environment.
What it Does:
Adjusts the timing between the early reflections. Early reflections
are the first group of reflections you hear before the subsequent,
dense reverberation begins.
What it Does:
Adjusts the delay between the direct sound and the first reflection
heard by the listener.
Control Range:
0.1 – 2.0
Standard setting is 1.0.
Control Range:
1 – 49 milliseconds
Changing this parameter from 1 to 2 increases the apparent
volume of the room eight times (length, width, and height all
doubled).
For a small living room this parameter would be set for a small
value. Large values for a big room. Larger values produce an echo
effect.

EFCT TRIM (Effect Trim)
How it Affects the Sound:
Performs fine adjustment of the level of all the effect sounds.
The natural reverberation time of a room depends primarily on its
size and the characteristics of its inner surfaces. This parameter,
therefore, changes the apparent size of the acoustic environment
over an extremely wide range.
Control Range:

DELAY
What it Does:
Adjusts the amount of time it takes for the level of the dense,
subsequent reverberation sound to decay by 60 dB (@ 1 kHz).
Adjusts the delay between the direct sounds (at the main left,
center and main right channels) and the effect sounds (at the front
effect and rear effect channels). The larger the value, the later the
effect sounds are generated.
Control Range:
1.0 – 5.0 seconds.
Control Range:
The reverb time in a small-to-medium size hall would be between
