FEATURES
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. 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 halls, jazz clubs, theaters, etc. from around the world, to
allow you to accurately recreate any one of these live performance
environments, all in your own home.
