Inside the YSP-5600’s front grille are 44 precisely calculated and positioned speakers. In order to create 7-channel sound beams (Front left/right, Center, Surround left/right, Height left/right), each of the speakers is controlled by an individual delay time and is driven with its own independent amplifier circuit. These beams are projected onto the walls and ceiling, to be reflected accurately to the listening position. This creates the same sound as real wall and ceiling speakers, not a virtual sound, but real 3D surround sound reproduction. In addition, the YSP-5600 uses the Surround channel sound beam for Surround Back, and the Surround channel is phantom merged to support the equivalent of up to 7.1.2-channel Dolby Atmos or DTS:X reproduction.
