INTRODUCTION

What’s DSP?

Introduction

Welcome to the exciting world of digital home entertainment.
This unit is one of the most complete and advanced AV
amplifier 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.

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.

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.

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 Surround

Dolby Pro Logic 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.

4

Most video tapes and laser discs include Dolby Pro Logic
Surround encoding as do many TV and cable broadcasts. The
Dolby Pro Logic Surround 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.

Dolby Digital

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 “subwoofer channel” or “LFE
channel”.) This channel is counted as 0.1, thus giving rise to
the term 5.1 channels in total.

Compared to Dolby Pro Logic 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 Stereo 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 Stereo Digital theatrical films now underway will provide
an immediate source of Dolby Digital encoded video software.

DTS Digital Surround

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 surround­sound 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.)

CINEMA DSP

INTRODUCTION

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.

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 Surround­decoded 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 Stereo theater.

This combination is available when the digital sound field
program No. 8, 9, 10, 11 or “PRO LOGIC/Enhanced” of No.
12 is selected, and the input signal of the source is analog,
PCM audio or encoded with the Dolby Digital in 2-channels.

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.

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
Stereo Digital theater or DTS installed theater. This is the
most ideal home theater sound at the present time.

This combination is available when the digital sound field
program No. 8, 9, 10, 11 or “DOLBY DIGITAL (or DTS
DIGITAL SUR.)/Enhanced” of No. 12 is selected, and the
input signal of the source is encoded with the Dolby Digital
(except in 2-channels) or encoded with the DTS.

PREPARATION

Speaker setup

m Setting up your speaker system

This unit has been designed to provide the best sound field
quality with a full seven-speaker system setup, using a pair of
main speakers to output main source sounds, two extra pairs
of effect speakers to generate the sound field plus one center
speaker for dialog. We therefore recommend that you use a
seven-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 seven-speaker system later. In the 4 or 5 speaker
system, the Digital Sound Field Processing is still performed,
but the main speakers are used for both the main channels
and the front effect channels.

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.

m Speakers and speaker placement

Your full seven-speaker system will require three speaker
pairs: the MAIN SPEAKERS (your normal stereo speakers),
the FRONT EFFECT 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, the FRONT
EFFECT and REAR SPEAKERS.

Place the MAIN SPEAKERS in the ordinary position.
Place the FRONT EFFECT SPEAKERS further apart than the
MAIN SPEAKERS, on either side of and 0.5–1m behind and
above the MAIN SPEAKER pair.
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.

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.

1E. SYS. SETUP—Set to 5ch. (See page 27.)
1A. CENTER SP—Set to NONE. (See page 26.)

5 Speaker System

Good for Audio/Video sources.

By the use of a center speaker, center sounds (dialog, vocals
etc.) are precisely localized.

1E. SYS. SETUP—Set to 5ch. (See page 27.)
1A. CENTER SP—Set to LRG or SML. (See page 26.)

6 Speaker System

Good for sound fields from 2-channel stereo sources.

When a normal stereo source is played back with the sound
field programs No. 1 through No. 7, a sound effect matching
that of a 7-speaker system can be obtained. The addition of
front left and right effect speakers produces a more effective
sound field.

7 Speaker System

This is the recommended speaker system, providing the
best sound effects.

The rear speakers and the front effect speakers produces a
360-degree sound field, and the center speaker provides
precise center localization.
You can experience the amazing YAMAHA “CINEMA DSP”
sound fields completely with the 7 speaker system.

PREPARATION

English

If your CD player, MD recorder, 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 only analog audio signal terminals
of this unit. You can switch the selection of input signals
between “digital” and “analog” easily. (See page 35 for details.)
* However, if you connect an MD recorder or DAT to this

unit’s OPTICAL TAPE/MD IN and OUT terminals, it can
record input sources connected to this unit’s OPTICAL
digital signal input terminals.

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.

●

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.

(Refer to page 35 for details.)

It is also necessary to connect the DVD/LD/CD combi-player to
this unit’s analog audio signal input terminals regardless of the
DOLBY DIGITAL RF signal connection. This is for playing back
a source with Dolby Pro Logic Surround decoded or in normal
stereo (or monaural).

DVD/LD/CD
combi-player

You must also connect the optical digital signal output terminal
of the DVD/LD/CD combi-player to the OPTICAL DVD/LD
digital signal input terminal of this unit.
This connection is necessary for playing back a DVD source
with Dolby Digital or DTS decoded, and playing back an LD
source with DTS decoded.

Note

DOLBY DIGITAL RF audio input signal cannot be recorded by
a tape deck, MD recorder or VCR. To record a source played
back on the DVD/LD/CD combi-player, it must be connected to
the OPTICAL digital audio signal input terminal and analog
audio signal input terminals of this unit.

Notes about the Video superimpose

●

If you watch a video source that is connected to both S
VIDEO and VIDEO input terminals of this unit, signals of
screen display information are output from only the S
VIDEO MONITOR OUT terminal.

●

When no video signal is input to either S VIDEO or VIDEO
input terminals of this unit, signals of screen display
information are output from both S VIDEO MONITOR OUT
and VIDEO MONITOR OUT terminals with a color
background.
* For China and General models, if the PAL/NTSC switch

on the rear panel is set to “PAL”, nothing will be output
from either S VIDEO MONITOR OUT or VIDEO
MONITOR OUT terminal in this case.

S VIDEO terminals

This unit provides you with S VIDEO terminals in addition
to standard type VIDEO terminals.
S VIDEO terminals transmit video signals separated into
luminance (Y) signals and color (C) signals. In comparison
with S VIDEO terminals, standard type VIDEO terminals
