Virtual 3D

Surround sound typically requires several speakers

situated in front of and behind the listening position, which

requires a substantial amount of space that may not always

be available.

In addition to the ordinary surround sound reproduction

using several speakers, this unit enables you to enjoy

surround sound effect with only two speakers by using

Yamaha's unique "Virtual 3D (three-dimensional)"

technology.

When you listen to a performance in a concert hall, jazz

club, or other live music venue, you not only hear the direct

sound coming from the musical instruments and singers,

but also the "early reflections" and natural reverberation.

Early reflections are the initial sound waves that bounce off

the floor, ceiling, and walls. Natural reverberation is made

up of sound waves that gradually attenuate as they bounce

repeatedly off multiple surfaces.

Virtual 3D, which is used by this unit's sound field

programs, simulates the surround effect provided by rear

and center speakers, creating "virtual" surround speakers,

as shown, so even with only two front speakers, you can

still enjoy surround sound.

Since the way you hear early reflections and reverberation

depends on the shape and size of the building as well as

the material and construction of the walls and ceiling, each

venue has its own unique "sound," called its "sound field."

At Yamaha, we have measured all the elements that make

up a typical sound field—direction and level of the

reflections, band-width characteristics, and delay times—at

famous concert halls and opera houses around the world.

The information gained in this process has been converted

into programs that can be reproduced using Yamaha's DSP

technology. Using its on-board DSP, this unit can process

any audio source and recreate the atmosphere of the

original venue.
