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 actual music venues to allow you to accurately
recreate 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.
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 Su DSP
You can also enjoy a combination of Dolby Pro Logic Surround
and DSP in the sound field program “
PRO LOGIC
ENHANCED”.
It recreates the surround effect of a movie theater, effectively
duplicating its multiple surround loudspeaker system,
completely surrounding the listener with the sounds of the
action taking place on the screen.
