DIGITAL SOUND FIELD PROCESSOR (DSP)
The Digital Sound Field Processor (DSP) built into this system takes 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 this unit will sonically transform your room into a wide range of
listening environments –movie theater, concert hall, and so on. In addition, you get incredible realism from sources
encoded with Dolby Surround using the built-in Dolby Pro Logic Surround Decoder.
Please read this operation manual carefully and store it in a safe place for later reference.
Digital Sound Field Processing
English
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.
Dolby Pro Logic Surround
This unit employs a Dolby Pro Logic Surround decoder
similar to professional Dolby Stereo decoders used in
many movie theaters. By using the Dolby Pro Logic
Surround decoder, you can experience the dramatic
realism and impact of Dolby Surround movie theater
sound in your own home. Dolby Pro Logic employs a
four-channel five-speaker system. The Pro Logic
Surround system divides the input signal into four levels:
the left and right main channels, the center channel
(used for dialog), and the rear surround sound channels
(used for sound effects, background noise, and other
ambient noises). The 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.
Dolby Surround is encoded on the sound track of prerecorded video tapes, laser discs, and some TV/cable
broadcasts. When you play a source encoded with Dolby
Furthermore, our technicians, armed with sophisticated
measuring equipment, have even made it possible to
capture the acoustics of a variety of venues such as an
actual concert hall and theater to allow you to accurately
recreate one of several actual live performance
environments, all in your own home.
Surround on this unit, the Dolby Pro Logic Surround
decoder decodes the signal and distributes the
surround-sound effects.
This Dolby Pro Logic Surround Decoder employs a
digital signal processing system. This system improves
the stability of sound at each channel and minimizes
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.

Dolby Pro Logic Surround + DSP
Dolby Surround sound system shows its full ability in a
large movie theater, because movie sounds are
originally designed to be reproduced in a large movie
theater using many speakers. It is difficult to create a
sound environment similar to that of a movie theater in
your listening room, because the room size, materials of
inside walls, the number of speakers, and other factors
of your listening room are much different from those of a
movie theater.
Yamaha DSP technology made it possible to present
you with nearly the same sound experience as that of a
large movie theater in your listening room by
compensating for lack of presence and dynamics in your
listening room with its original digital sound fields
combined with Dolby Surround sound field.
The combination of Dolby Pro Logic Surround and DSP
is used on the sound field program “ PRO LOGIC
ENHANCED”.
The YAMAHA “CINEMA DSP” logo indicates these
programs are created by the combination of Dolby Pro
Logic and YAMAHA DSP technology.

SETTING UP THE SPEAKERS
Before you make connections, place all units in this system in their proper positions. Above all, the positioning of the
speakers is important because it controls the whole sound quality of this system.
Position the speakers on the basis of your listening position by following the instructions in this section.

Subwoofer
Speaker configuration
This system employs a 6-speaker configuration: 2 front
speakers, 2 rear speakers, a center speaker and a
subwoofer.
The front speakers are used for the main source sound
plus the effect sounds. The rear speakers are used for
the effect and surround sounds, and the center speaker
is for the center sounds (such as dialog.). The
subwoofer is for reinforcing low frequencies of the main
source sound and the center sound.
Placing speakers
Front speakers: On both sides of the TV and at
almost the same height as the TV.
Rear speakers: Behind your listening position,
facing slightly inward. Nearly six
feet (approx. 1.8 m) up from the
floor.
Center speaker: Precisely between the front
speakers.
Subwoofer: The position of the subwoofer is not
so critical because low bass tones
are not highly directional.
Note
Although FRONT, REAR, and CENTER speakers are
magnetically shielded, there may be some
influence on the TV picture depending on the type
of TV or the placement of the speakers. In such a
case, place the speakers far enough from the TV so
that there is no influence on the TV picture.

When installing the center speaker on the TV, be sure to
secure the center speaker to the TV using the velcro strips
provided so that it does not fall.
Notes
• Do not place the center speaker on top of a TV
whose area is smaller than the bottom area of the
center speaker, as the center speaker may drop and
cause personal injury.
• Although this center speaker is a magnetically
shielded type, there may be some influence on the
TV picture depending on the type of TV or the
placement of the center speaker. In such a case,
place the center speaker apart from the TV so that
there is no influence on the TV picture.
• Be sure to remove all dust, debris, oil, and other
substances adhering to the section where the velcro
strip is affixed. If this section is dirty, the velcro strip
will not affix properly, and the center speaker may
move or fall.
• When peeling off the backing paper of the velcro
strips, be careful not to touch the adhesive surface.
Doing so harms the adhesion strength.
• If there is a gap between the center speaker and TV,
turn and extend the adjuster on the bottom rear
section of the center speaker so that the center
speaker is stable.

USING THE AV-S7
USING THE AV-S7
This system incorporates a sophisticated, multiprogram digital sound field processor. The processor
allows you to electronically expand and change the
shape of the audio sound field from both audio and
video sources, creating a theater-like experience in
your listening room. You can create an excellent audio
sound field by selecting a suitable sound field program
(this will, of course, depend on what you will be
listening to) and adding desired adjustments.
In addition, this unit incorporates a Dolby Pro Logic
Surround decoder for multi-channel sound reproduction
of sources encoded with Dolby Surround.
The operation of the Dolby Pro Logic Surround decoder
can be controlled by selecting the DSP program,
PRO LOGIC or PRO LOGIC ENHANCED.
PROGRAM
This program is used for playing of sources encoded with Dolby Surround.
PRO LOGIC
ENHANCED
Enhancing the “Normal” Dolby Pro Logic, the DSP technology simulates the multi-surround
speaker systems of a 35 mm movie theater. This effect creates a wide surround sound field,
and expands the sound stage with an improved presence image. This program is used for
musical based movies, as well as drama and comedy based movies.
Brief Overview of Digital Sound Field
Programs
The following list gives you a brief description of the
sound fields produced by each DSP program. Keep in
mind that most of these are precise digital recreations
of actual acoustic environments. The data for these
sound fields was recorded at actual locations using
sophisticated sound field measurement equipment.
Note
The channel level balance between the left and
right rear effect speakers may vary depending on
the sound field you are listening to. This is because
most of these sound field recreations are actual
acoustic environments.
FEATURE
PRO LOGIC
CONCERT
SPORTS
MONO MOVIE
This program is also used for playing of sources encoded with Dolby Surround.
The application of a sophisticated digital signal processing system reduces crosstalk and
directs or steers the sound source more smoothly and precisely, as compared to conventional
types.
This program is effective for music videos and gives excellent depth and clarity for vocals.
For opera, the orchestra and stage are ideally recreated, making you feel as if you were in an
actual concert hall.
This program is ideal for enjoying sports programs which take place in arenas, indoor
stadiums, or other venues.
This program is designed specifically to enhance mono source programs. Compared to a
strictly mono setting, the sound image created in this mode is wider and slightly forward of the
speaker pair, lending an immediacy to the overall sound. It is particularly effective when used
with old mono movies, news broadcasts and dialog.
