PROFILE OF THIS UNIT
You are the proud owner of Yamaha AV-90PY, the stereo amplifier –an extremely sophisticated audio component. The Digital
Sound Field Processor (DSP) built in this unit 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 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 Dolby-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.
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 hall, theater, etc. to
allow you to accurately recreate one of several actual 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
action on the screen while getting a stereo effect as well.
“ENHANCED” Dolby Pro Logic Surround
The AV-90PY has a second mode of Dolby Pro Logic Surround
processing called “Enhanced Dolby Pro Logic Surround”
processing. Enhanced Dolby Pro Logic Surround processing
recreates the surround effect of a movie theater, effectively
duplicating their multiple surround loudspeaker system,
completely surrounding the listener with the sounds of the
action taking place on the screen.
4
This Dolby Pro Logic Surround Decoder employs a digital
signal processing system. This system increases sound
stability at each channel and minimizes crosstalk between
channels, compared to conventional analog Dolby signal
processing.
In addition, this unit features a built-in automatic input balance
control. This circuit always presents you the best surround
conditions without performing manual adjustments.
SPEAKER SETTING UP FOR THIS UNIT
SPEAKERS TO BE USED
This unit is designed to provide the best sound-field quality with 5 speaker configuration. The speakers to be used with this unit will
be mainly front speakers, rear speakers, and a center speaker. (You can delete a center speaker. Refer to the “4-Speaker
Configuration” shown below.)
The front speakers are used for the output of the main source sound and the effect sound. They will probably be your present
stereo speaker system. The rear speakers are used for the output of the effect sound. And the center speaker is used for the
output of the center sound (dialogue etc.) encoded with the Dolby Surround. The rear and center speakers do not need to be equal
with the front speakers. However, all the speakers should have high enough power handling to accept the maximum output of this
unit that will drive them.
SPEAKER CONFIGURATION
5-Speaker Configuration
This configuration is the most effective and recommended. In
this configuration, the center speaker is necessary as well as
the rear speakers. If the digital sound field program is in the
DOLBY PRO LOGIC or ENHANCED, conversations will be
output from the center speaker and the ambience will be
excellent.
●
Set the center mode to the “NORMAL” or “WIDE” position.
(For details, refer to the page 11.)
Front L
Center
4-Speaker Configuration
The center speaker is not used in this configuration. If the
digital sound field program is in the DOLBY PRO LOGIC or
ENHANCED, the center sound is output from the left and the
right front speakers. However, the sound effect of other
programs can be the same as that of the 5-speaker
configuration.
●
Be sure to set the center mode to the “PHANTOM” position.

SPEAKER PLACEMENT
The recommanded speaker configuration, the 5-speaker configuration, will require two speaker pairs: front speakers (your normal
stereo speakers), and rear speakers, plus a center speaker. When you place these speakers, refer to the following.
Front:
In normal position. (The position of your present
stereo speaker system.)
Rear: Behind your listening position, facing slightly inward.
Nearly six feet up from the floor.
Center: Precisely between the front speakers. (To avoid
interference to TV sets, use a magnetically shielded
speaker. If, however, it is not effective, keep the
speaker away from TV sets.)

YAMAHA ACTIVE SERVO TECHNOLOGY
High-amplitude
bass sound
Cabinet
Air woofer
(Helmholtz resonator)
Port
Active Servo
Processing Amplifier
Signals
Negative-impedance
output drive
Signals of low amplitude
The theory of the Active Servo Technology is based upon two
major factors, the Helmholtz resonator and negativeimpedance drive. Active Servo Processing speakers
reproduce the bass frequencies through an “air woofer”, which
is a small port or opening in the speaker’s cabinet. This
opening is used instead of, and performs the functions of, a
woofer in a conventionally designed speaker system. Thus,
signals of low amplitude within the cabinet can, according to
the Helmholtz resonance theory, be output from this opening
as waves of great amplitude if the design is such that the size
of the opening and the volume of the cabinet are in the correct
proportion to satisfy a certain ratio.
In order to accomplish this, moreover, the amplitudes within
the cabinet must be both precise and of sufficient power
because these amplitudes must overcome the “load”
presented by the air that exists within the cabinet.
6
Thus it is this problem that is resolved through the
employment of a design in which the amplifier functions to
supply the signals. If the electrical resistance of the voice coil
is reduced to zero, the movement of the speaker unit would
become linear with respect to signal voltage, and, to
accomplish this, a special negative-impedance output-drive
amplifier for subtracting output impedance of the amplifier is
used.
By employing negative-impedance drive circuits, the amplifier
is able to generate precise, low-amplitude low-frequency
waves with superior damping characteristics, and these waves
are then radiated from the cabinet opening as high-amplitude
signals. The system can, therefore, by employing the
negative-impedance output drive amplifier and a speaker
cabinet with the Helmholtz resonator, reproduce an extremely
wide range of frequencies (28 Hz – 20 kHz) with amazing
sound quality and less distortion.
The features described above, then, are combined to be the
fundamental structure of the Active Servo Technology.

CONNECTING SPEAKERS
aConnect the SPEAKERS terminals to your speakers with wire
of the proper gauge, cut to be as short as possible. If the
connections are faulty, no sound will be heard from the
speakers. Make sure that the polarity of the speaker wires is
correct, that is, + and – markings are observed. If these wires
are reversed, the sound will be unnatural and will lack bass.
Do not let the bare speaker wires touch each other and do
not let them touch the metal parts of this unit as this could
damage this unit and/or speakers.
● Use speakers with the specified impedance shown on the
rear of this unit.

FEATURE
This program is effective on the play of the sources encoded with the Dolby Surround.
The employment of the digital signal processing system improves crosstalk and transfers the sound
source more smoothly and precisely,comparing with the conventional type. A stable movie sound field is recreated.
This program is effective on the play of the sources encoded with the Dolby Surround.
Enhancing the “Normal” Dolby Pro Logic, the DSP technology simulates the multi-surround speaker
systems of the 35 mm film theater, so widening the surrounded-sound field with greater presence.
This program is effective on music videos and excellent in depth and clarity for vocals. For opera, the
orchestra and stage are ideally recreated, so letting you feel as if you were in an actual concert hall.
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 dialogue.
ROCK CONCERT
This program will suit to rock music. A big, powerful sound is reproduced lively and dynamically.
CONCERT HALL
In this program, the center seems even more deeply behind the front speaker pair, creating an expansive,
large hall ambience.
OFF Switch : When any program is not used with the selected source, press this switch.
The sound is output only from the front speakers.

Notes on Operation of Sound Field Programs
●
In the CONCERT VIDEO, MONO MOVIE, ROCK CONCERT
and CONCERT HALL, no sound is heard from the center
speaker.
●
When the monaural sound source is played in the DOLBY
PRO LOGIC or ENHANCED, no sound is heard from the
front speakers and the rear speakers. Sound is heard only
from the center speaker. However, if the center mode is in
the PHANTOM, the front speakers output the sound of the
center speaker.
●
If you connect an external amplifier to this unit, see if it has a
built-in surround sound or ambience circuitry. If it does, then
be sure that the surround or ambience circuitry on that
amplifier is off while you are using the digital sound field
processor’s Dolby Pro Logic Surround decoding function.
●
When this unit is in the Dolby Pro Logic Surround mode, if
the main-source sound is considerably altered by
overadjustment of the BASS or TREBLE controls, the
relationship with the center and rear channels may produce
an unnatural effect.
Description of Dolby Pro Logic Surround
DOLBY PRO LOGIC SURROUND: This unit employs the
Dolby Pro Logic Surround system. This system is similar to
professional Dolby Stereo decoders used in movie theaters.
The Dolby Pro Logic Surround system, by employing a fourchannel system, divides the input signals into four levels: the
left and right main channels, the center channel (to characterize
dialogue), and the rear surround-sound channels (to
characterize sound effects, background noise and other ambient
noise).
Dolby Surround is encoded on the sound track of commercially
available video cassettes and video discs as well. When you
play a source encoded with Dolby Surround on your home video
system, the Dolby Pro Logic Surround mode on this unit
decodes the signal and feeds the surround-sound effects.
The Dolby Pro Logic Surround mode may not be always
effective on video sources not encoded with Dolby Surround.

REMOTE CONTROL “LEARNING” FUNCTION
The keys on this remote control transmitter can be programmed to “learn” key-functions from other remote control transmitters. By
using this feature, this unit can then be used in place of one or more other remote control transmitters, thus making operation of
your various audio and video components more convenient. Moreover, each key can learn two functions by switching the learning
page. Use the included user program sheets to indicate a new function learned for each key.
Note
There may occasionally be instances, due to the signal-coding and modulation employed by the other remote control transmitter,
that this unit will not be able to “learn” its signals.
To Learn a New Function
Notes
● When you operate the desired component with this remote
control transmitter, TRANSMIT/LEARN indicator will flash
steadily.
● The originally preset function of a key is still available in the
USER position if a new function has not been learned to the
key.
● Successful learning to a key results in the erasure of
previously learned functions and their replacement by the
newly learned ones.
● If there is no more room in the memory area for a function to
be learned, the TRANSMIT/LEARN indicator will flash two
times. In this case, even if some keys are not occupied with
functions from other remote control transmitters, no further
learning is possible.
