OUTLINE OF THIS UNIT
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 ordinary surround sound reproduction using several speakers, this unit enables you to enjoy surround sound effects with only two speakers by using Yamaha’s unique “Virtual 3D”

Typical surround system
Virtual 3D, which is used by this unit’s sound field programs, simulates the surround effect provided by surround and center speakers, creating “virtual” surround speakers, as shown, so even with only two front speakers, you can still enjoy surround sound.

Digital Sound Field Processing (DSP)
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.
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,
