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, b ut chances are y ou’ll still notice something missing, the acoustic environment of the live concert hall. Extensive research into the e xact 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 halls, jazz clubs, theaters, etc.from around the world, to allow you to accurately recreate an y one of these liv e performance environments, all in your o wn home .

Dolby Pro Logic Surround

The Dolby Pro Logic Surround Decoder program lets y ou experience the dramatic realism and impact of Dolby Surround mo vie theater sound in your own home.Dolby Pro Logic gets its name from its professional-grade steering logic circuitry, which provides greater effective channel separ ation for a much higher degree of realism than the “passive”Dolby Surround circuits found in toda y’s typical home audio/video equipment.Dolby Pro Logic Surround provides a true center channel, so that there are four independent channels, unlik e 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 the action on the screen while experiencing good stereo imaging.

This Dolby Pro Logic Surround Decoder employs a digital signal processing system.This system improves the stability of sound at each channel and 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

Additionally you can enjoy sound en vironment created by the

combination of Dolby Pro Logic and YAMAHA DSP.

Precise sound movement and orientation by the Dolby Pro Logic technology is added to sound fields which are precisely recreated on the basis of actual acoustic environments by the DSP technology, so it is suitable for any Audio/Video source with video image. This combination is used on sound field programs No. 8 through No.11, and “Enhanced DOLBY PRO LOGIC” of No.12.

The YAMAHA “CINEMA DSP”logo indicates these programs are created by the combination of Dolby Pro Logic and YAMAHA DSP technology.

Setting Up Your Speaker System

This unit has been designed to provide the best sound field quality with a full sev en-speak er system setup, using two extra pairs of effect speakers to gener ate the sound field plus one center speaker for dialog, when using Dolb y Pro Logic Surround decoding. We theref ore recommend that y ou use a seven-speaker setup.A four-speaker system using only one pair of effect speakers f or 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 upgr ade 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

With digital sound field programs No .8 through No.12, by using either the Directional Enhancement circuit or the Dolby Pro Logic decoder, decoded signals will be output from the center channel. Therefore, if y ou w ant to maximiz e the performance of your Audio/Video home theater system, it is recommended that y ou use a center channel speaker .

If for some reason it is not practical to use a center speak er, it is possible to enjoy mo vie vie wing without it.Best results, howe v er, are obtained with the full system.

It is also possible to further expand your system with the addition of a subwoofer and amplifier.You may wish to choose the convenience of a Yamaha Active Servo Processing Subwoofer System, which has its own built-in pow er amp.

4 Speaker System

Simplest system.

You can enjoy widely diffused sound by only adding two additional speaker units at the rear.

FRONT MIX switch—Set to ON. (See page 13.) Center Mode—Set to PHNTM. (See page 26.)

5 Speaker System

Good for Audio/Video sources and Dolby Pro Logic Surround.

With sound field programs No. 8 through No. 12, which utilize the center speaker effect, more precise center localization can be obtained.

FRONT MIX switch—Set to ON. (See page 13.) Center Mode—Set to NRML or WD. (See page 26.)

6 Speaker System

Good for sound fields from 2-channel stereo sources.

With 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.

FRONT MIX switch—Set to OFF. (See page 13.) Center Mode—Set to PHNTM. (See page 26.)

7 Speaker System

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

With sound field programs No. 1 through No. 7, using both sets of effect speakers (front and rear), reproduces the most effective sound field. With the sound field programs No. 8 through No. 12, the center speaker provides precise center localization.

FRONT MIX switch—Set to OFF. (See page 13.) Center Mode—Set to NRML or WD. (See page 26.)

Four Possible Types of Speaker System Configurations Recommended

English

Speakers and Speaker Placement

Your full seven-speak er system will require three speaker pairs: the MAIN SPEAKERS (your normal stereo speakers), the FRONT EFFECT SPEAKERS and the REAR EFFECT SPEAKERS, plus the CENTER SPEAKER.You may also be using a subwoofer.

You will probably use your present stereo speak ers as the MAIN SPEAKER pair.The front effect and rear effect do not need to be equal with the MAIN SPEAKERS, although the center speaker should be as close as possible.They should have enough power handling capacity to accept the maximum output of the DSP system or the external amps that will drive them.

Place the MAIN SPEAKERS in the normal position.

Place the FRONT EFFECT SPEAKERS further apart than the MAIN SPEAKERS, on either side of and a fe w feet behind and above the MAIN SPEAKER pair.

Place the REAR EFFECT SPEAKERS behind your listening position.They should be nearly six feet up from the floor.

Place the CENTER SPEAKER precisely between the two MAIN SPEAKERS.(To avoid interference, keep the speaker abo ve or below the television monitor, or use a magnetically shielded speaker.)

If using a SUBWOOFER, such as a Yamaha Active Servo Subwoofer System, the position of the speak er is not so critical because low bass tones are not highly directional.
