Processor (DSP) built into 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 totally new listening environment – movie theater, concert hall, and so on. In
addition, you get incredible realism from Dolby Surround-encoded video sources 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. 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 live performance environments in your own home.
Dolby Pro Logic Surround
The Dolby Pro Logic Surround Decoder program lets you
experience the dramatic realism and impact of a 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 front and rear
channel separation for a much higher degree of realism than
the “passive” Dolby Surround circuits found in less
sophisticated home audio/video equipment. Dolby Pro Logic
Surround provides a true center channel, so 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. 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.
Dolby Pro Logic Surround + DSP
Additionally you can enjoy sound environment 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 “DOLBY PRO LOGIC ENHANCED”, “70 mm MOVIE
THEATER”, “TV THEATER” and “SPORTS”.
The YAMAHA “CINEMA DSP” logo indicates these programs are
created by the combination of Dolby Pro Logic and YAMAHA
DSP technology.
