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. The RP-U100 uses 
Yamaha’s unique “Virtual 3D” tech-
nology to simulate a typical 
surround sound system using only 
two speakers. Virtual 3D, which is used by the RP-U100’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.
 
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, 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, the RP-U100 
can process any audio source and recreate the atmosphere of the original venue.
