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.

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.
