Welcome to the exciting world of digital home entertainment.
This unit is one of the most complete and advanced AV
receiver available. Some of the more advanced features may
not be familiar to you, but they are easy to use. State-of-the-art
technologies such as Dolby Digital and Digital Theater
Systems (DTS) may be new to your home, but you have
probably experienced the amazing realism they bring to feature
films in theaters around the world.
To make the listening experience even more enjoyable, this
unit includes a number of exclusive, digitally created listening
environments known as digital sound fields. Choosing a sound
field program is like transporting yourself to such venues as an
outdoor arena, a European church, or a cozy jazz club. Take
some time now to read more about these features and enjoy
the new experiences this unit brings to your home theater.
Digital Sound Field Processing
Technological advances in sound reproduction over the last 30
years have enhanced the listening experience with improved
clarity, precision and power. However, something has still been
missing: The atmosphere and acoustic ambiance of the public
venue. Our Yamaha engineers have extensively researched
the nature of sound acoustics and the way sound reflects
inside a room. We sent these engineers to famous theaters
and concert halls around the world to measure the acoustics of
those venues with sophisticated microphones. The data they
collected is used to recreate these environments in digital
sound fields. Some of these digital sound fields are created
using data measured directly at the original venue; others are
created from combinations of data to form unique
environments for specific purposes.
Of course, that only solves half of the problem. These
engineers have no way of knowing the acoustics of your
listening room, so we’ve made it possible for you to adjust the
various parameters of this data to tailor each virtual venue to
your taste. You can use these sound fields to enhance any
source and in combination with any of the following surround
sound technologies. Some are designed especially for music,
and some especially for movies.
Dolby Pro Logic
Dolby Surround has been used in movie theaters since the
mid-seventies. It has also been available in home
entertainment systems since the late eighties and continues to
be a popular format for home theater systems. It uses four
discrete channels and five speakers to reproduce realistic and
dynamic sound effects: two main channels (left and right), a
center channel for dialog, and a rear channel for special sound
effects. The rear channel reproduces sound within a narrow
frequency range.
Most video tapes and laser discs include Dolby Surround
encoding as do many TV and cable broadcasts. The Dolby Pro
Logic decoder built into this unit employs a digital signal
processing system that stabilizes each channel for even more
accurate sound positioning than is available with standard
analog processors.
Introduction
What’s DSP?
INTRODUCTION

English
Dolby Digital is the next level of Dolby Surround sound system
developed for 35 mm film-movies by employing low bit-rate
audio coding.
Dolby Digital is a digital surround sound system that provides
completely independent multi-channel audio to you. Dolby
Digital provides five full range channels in what is sometimes
referred to as a “3/2” configuration: three front channels (left,
center and right), and two surround channels. A sixth bass-only
effect channel is also provided for output of LFE (low frequency
effect), or low bass effects that are independent of other
channels. (This is called the “LFE channel”.) This channel is
counted as 0.1, thus giving rise to the term 5.1 channels in
total.
Compared to Dolby Surround that is referred to a “3/1” system
(left front, center, right front and just one surround channel),
Dolby Digital features two surround channels, called stereo or
split surrounds, each offering the same full range fidelity as the
three front channels.
By using the built-in Dolby Digital decoder, you can experience
the dramatic realism and impact of Dolby Digital theater sound
in your home.
Wide dynamic range of sound reproduced by the five full range
channels and precise sound orientation by the digital sound
processing presents listeners much excitement and realism
that has never been experienced before.
Dolby Digital forms 5.1 channels as mentioned left, and
moreover, it can also form fewer channels, for example 2
channel stereo and monaural. You may be able to find some 2
channel stereo and/or monaural sources encoded with Dolby
Digital in the market.
Laserdisc and DVD are home audio formats that could benefit
from Dolby Digital. In the near future, Dolby Digital will also be
applied to DBS, CATV and HDTV. The ongoing release of
Dolby Digital theatrical films now underway will provide an
immediate source of Dolby Digital encoded video software.
Manufactured under license from Dolby Laboratories. “Dolby”,
“Pro Logic” and the double-D symbol are trademarks of Dolby
Laboratories.
DTS (Digital Theater Systems) system was developed to
replace analog soundtracks of movies with six discrete
channels of digital soundtracks, and now, it is installed in many
theaters around the world. The DTS digital playback system
changed the way we experienced movies in theaters with six
discrete channels of superb digital audio.
The DTS technology, through intense research and
development, made it possible to deliver a similar
encode/decode discrete technology to home audio surround-
sound entertainment.
The DTS Digital Surround is an encode/decode system which
delivers six channels of master-quality, 20-bit audio; technically
5.1 channels, which means 5 full-range (left, center, right and
two surround) channels, plus a subwoofer (LFE) channel (as
“0.1”). It is compatible with the 5.1 speaker configurations that
are currently available for home theater systems
The DTS Digital Surround algorithm is designed to encode the
six channels of 20-bit audio onto some laserdiscs, compact
discs and DVDs with considerably less data-compression.
By using the DTS decoder built into this unit, you can
experience the dramatic realism and impact of the DTS
installed theater’s high quality sound in your home.
Laserdisc, compact disc and DVD are home audio format
within which DTS can represent its high quality multi-channel
audio. (In addition to movies on laserdiscs, many exciting new
multi-channel music recordings will also become available in
the form of DTS-encoded compact discs.)

Dolby Pro Logic + 2 Digital Sound Fields
Digital sound fields are created on the presence side and
the rear surround side of the Dolby Pro Logic decoded
sound field respectively. They create a wide acoustic
environment and emphasize surround-effect in the room,
letting you feel much presence as if you were watching a
movie in a popular Dolby Surround theater.
For details, refer to pages 48 to 49.
Dolby Digital or DTS + 3 Digital Sound Fields
Digital sound fields are created on the presence side and
the independent left and right surround sides of the Dolby
Digital-decoded or the DTS-decoded sound field
respectively. They create a wide acoustic environment and
much surround effect in the room without losing high
channel separation. With wide dynamic range of Dolby
Digital or DTS sound, this sound field combination lets you
feel as if you were watching a movie in the newest Dolby
Digital theater or DTS installed theater. This is the most
ideal home theater sound at the present time.
For details, refer to pages 48 to 49.
CINEMA DSP: Dolby Surround + DSP / DTS + DSP
The Dolby Surround sound and DTS systems show their full
ability in a large movie theater, because movie sounds are
originally designed to be reproduced in a large movie theater
that uses a multitude of speakers. Trying to create a sound
environment similar to that of a movie theater in your home is
difficult because of the room size, material inside the walls, the
number of speakers, and so on. In other words, your listening
room is very different from a movie theater.
However, Yamaha DSP technology allows you to create nearly
the same sound experience as that of a large movie theater in
your home by compensating for the lack of presence and
dynamics in the listening room with original digital sound fields
combined with Dolby Surround or DTS Digital Surround
sounds.
The YAMAHA “CINEMA DSP” logo indicates those programs
that are created by the combination of YAMAHA DSP
technology and Dolby Surround or DTS.

This unit has been designed to provide the best sound field
quality with a full five-speaker system setup, using a pair of
main speakers to output main source sounds, a pair of effect
speakers to generate the sound field plus one center speaker
for dialog. 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 five-
speaker system later.
Use of the center dialog speaker is
recommended
When playing back a source with Dolby Pro Logic decoded, or
playing back a source which contains center-channel signals
with Dolby Digital or DTS decoded, dialog, vocals etc. are
output from the center channel. Therefore, if you want to
maximize the performance of your Audio/Video home theater
system, it is recommended that you use a center channel
speaker.
If, for some reason, it is not practical to use a center speaker, it
is possible to enjoy the movie without it. Best results, however,
are obtained with the full system.
Use of a subwoofer expands your sound
field
It is also possible to further expand your system with the
addition of a subwoofer and amplifier. The use of a subwoofer
is effective not only for reinforcing bass frequencies from any
or all channels, but also for reproducing signals at the
subwoofer channel with high fidelity during playing back a
source with Dolby Digital or DTS decoded. You may wish to
choose the convenience of a Yamaha Active Servo Processing
Subwoofer System, which has its own built-in power amplifier.
Speaker setup
m Speakers and speaker placement
Your full five-speaker system will require two speaker pairs:
the MAIN SPEAKERS (your normal stereo speakers) and the
REAR SPEAKERS, plus the CENTER SPEAKER. You may
also be using a SUBWOOFER.
The MAIN SPEAKERS should be high performance models
and have enough power handling capacity to accept the
maximum output of your audio system.
Other speakers do not have to be equal to the MAIN
SPEAKERS. For precise sound localization, however, it is
ideal to use high performance models that can reproduce
sounds in full range for the CENTER SPEAKER and REAR
SPEAKERS.
Place the MAIN SPEAKERS in the ordinary position.
Place the REAR SPEAKERS behind your listening position.
They should be nearly 1.8m above 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.)
If using a SUBWOOFER, such as a Yamaha Active Servo
Processing Subwoofer System, the position of the speaker is
not so critical because low bass tones are not highly
directional.

5 Speaker System
The recommended system for enjoying Audio/Video
sources.
By the use of a center speaker, center channel sounds (dialog,
vocals etc.) are precisely localized.
1. CENTER SPEAKER—Set to “LRG” or “SML”.
(See page 27.)
4 Speaker System
Basic system.
You can enjoy widely diffused sound by only adding a pair of
rear speakers to a basic stereo speaker system.
However, center channel sounds must be output from the left
and right main speakers.
1. CENTER SPEAKER—Set to “NONE”. (See page 27.)

Notes
When you connect an audio/video unit to both of the digital
and analog terminals of this unit, make sure to connect to
both terminals of the same name.
Be sure to attach the covers when the OPTICAL terminals
are not being used, in order to protect the terminals from
dust.
The DOLBY DIGITAL RF signal output terminal of your
DVD/LD/CD combi-player, etc. cannot be connected directly
to this unit’s DVD/LD COAXIAL terminal.
See page 17 for proper connections to reproduce an LD
source encoded with Dolby Digital.
In order to make this unit perform successful DTS-decoding,
the DTS bitstream must not be altered, manipulated or
corrupted in the process of sending the DTS bitstream from
the DIGITAL OUT terminal of an external unit to a digital
signal input terminal of this unit.
All digital audio signal input terminals are applicable to the
sampling frequency of 32 kHz, 44.1 kHz and 48 kHz.
m Connecting to digital (OPTICAL and COAXIAL) terminals
If your CD player, LD player, DVD player, TV/satellite tuner,
etc. are equipped with coaxial or optical digital audio signal
output terminals, they can be connected to this unit’s COAXIAL
or OPTICAL, or both terminals.
Digital audio signals are transmitted with less loss than analog
audio signals. In addition, digital audio signal connections are
necessary, especially for an LD player, a DVD player or a CD
player to send signals encoded with Dolby Digital or DTS to
this unit.
To make an optical digital connection between this unit and an
external unit, remove the cover from each optical terminal, and
then connect them by using a commercially available optical
fiber cable that conforms to EIAJ standards. Other cables
might not function correctly.
Even if you connect an audio/video unit to the OPTICAL (or
COAXIAL) terminal of this unit, you must keep the unit
connected with the same named analog audio signal terminals
of this unit, because digital signal cannot be recorded by a tape
deck or VCR connected to this unit. You can switch the
selection of input signals between “digital” and “analog” easily.
