Digital Sound Field Processor (Dsp) - Yamaha AV-1 Owner's Manual

OUTLINE OF THIS SYSTEM

DIGITAL SOUND FIELD PROCESSOR (DSP)

The Digital Sound Field Processor (DSP) built into this system 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 wide range of
listening environments –movie theater, concert hall, and so on. In addition, you get incredible realism from sources
encoded with Dolby Surround using the built-in Dolby Pro Logic Surround Decoder.
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
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
Dolby Pro Logic Surround + DSP
Dolby Surround sound system shows its full ability in a
large movie theater, because movie sounds are
originally designed to be reproduced in a large movie
theater using many speakers. It is difficult to create a
sound environment similar to that of a movie theater in
your listening room, because the room size, materials of
inside walls, the number of speakers, etc. of your
listening room is much different from those of a movie
theater.
Yamaha DSP technology made it possible to present
you with nearly the same sound experience as that of a
large movie theater in your listening room by
compensating for lack of presence and dynamics in your
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, theater, etc. to allow you to
accurately recreate one of several actual live
performance environments, all in your own home.
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.
