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.

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.

PROFILE OF THIS UNIT

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.

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.
