Silent Cinema技術
Surround sound through headphones? Yamaha's Digital Sound Field Processing makes it possible. Using the same technology that created the two-speaker virtual surround sound program, we've developed a unique DSP mode for headphones called SILENT CINEMA. You don't need special headphones - just use the ones you've got and enjoy multi-channel sound in private
