PROFILE OF THIS UNIT
You are the proud owner of a Yamaha AV receiver — an extremely sophisticated audio component. The Digital Sound Field
Processor (DSP) built into this unit 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 totally new listening environment. In addition, you get incredible realism from
sources encoded with Dolby Surround using the built-in Dolby Pro Logic Surround Decoder.
This unit also has Karaoke functions. They are useful for enjoying Karaoke by using not only multisound sources for Karaoke, but
also normal music sources with vocals. Furthermore, sound-surrounding effects of the DSP expand your Karaoke enjoyment, in
which you will be absorbed in your singing.
Please read this operation manual carefully and store it in a safe place for later reference.
Digital Sound Field Processing (DSP)
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 develop their original
Digital Sound Field Processing Technology to re-create the
acoustic environment of a large concert hall in a home audio
listening room.
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, live house, etc. to re-create various types of actual live
performance environments for home audio use.
The DSP programs on this unit are made on the basis of this
technology.
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 pre-recorded
video tapes, laser discs, and some TV/cable broadcasts. When
you play a source encoded with Dolby 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.
Manufactured under license from Dolby Laboratories Licensing
Corporation. “Dolby”, the double-D symbol and “Pro Logic” are
trademarks of Dolby Laboratories Licensing Corporation.
Enjoying Karaoke with DSP
This unit is a new concept of AV receiver which has Karaoke
functions. They are two microphone input jacks, microphone
level control, echo level control, key level control and two
sound output modes (ONE TOUCH KARAOKE and VOCAL
AID) useful for singing Karaoke by using normal music sources
with vocals.
In addition, the built-in digital sound field processor presents
you with four programs which create sound fields suitable for
singing Karaoke. In those sound fields, you will sing Karaoke
with great feeling and sometimes excitedly.

SPEAKER SETUP
SPEAKERS TO BE USED
This unit is designed to provide the best sound-field quality with a 5 speaker configuration. The most effective speakers to use with
this unit are main speakers, rear speakers and a center speaker. You can use one rear speaker only instead of using two rear
speakers, and omit the center speaker. (Refer to the “SPEAKER CONFIGURATION” shown below.)
The main speakers are used for the main source sound plus the effect sounds. They will probably be the speakers from your
present stereo system. The rear speakers are used for the effect and surround sounds, and the center speaker is for the center
sounds (dialog etc.) within programs encoded with Dolby Surround. The center speaker needs to be equal in power to the main
speakers, although the rear speakers should not be equal. However, all the speakers should have high enough power handling to
accept the maximum output of this unit.
SPEAKER CONFIGURATION
5-Speaker Configuration
This configuration is the most effective and recommended one.
In this configuration, the center speaker is necessary as well as
the rear speakers. If the program DOLBY PRO LOGIC or
DOLBY 3 STEREO is selected, conversations will be output
from the center speaker and the ambience will be excellent.
• Set the center channel mode to the “NORMAL” or “WIDE”
position. (For details, refer to page17.)
4-Speaker Configuration (without the center speaker)
The center speaker is not used in this configuration. If the
program DOLBY PRO LOGIC is selected, the center sound is
output from the left and the right main speakers. The program
DOLBY 3 STEREO is useless in this configuration. However,
the sound effect of other programs can be almost the same as
that of the 5-speaker configuration.
• Be sure to set the center channel mode to the “PHANTOM”
position. (For details, refer to page 17.)
SPEAKER PLACEMENT
The recommended speaker configuration, the 5-speaker
configuration, will require two speaker pairs: main speakers
(your normal stereo speakers), and rear speakers, plus a
center speaker. When you place these speakers, refer to the
following.
Main: In normal position. (The position of your present
stereo speaker system.)
Rear: Behind your listening position, facing slightly inward.
Nearly 1.8 m (approx. six feet) up from the floor.
Center: Precisely between the main speakers. (To avoid
interference with TV sets, use a magnetically shielded
speaker.)

Note
As this unit is equipped with a monaural amplifier for the rear channel, sounds output from the rear speakers are in monaural. So,
you may use one rear speaker only instead of using two rear speakers. However, the use of two rear speakers is recommended
when there are more than one listener in the listening room.
When using one rear speaker, place it right behind your listening position.
