FEATURE
The built-in Dolby Pro Logic Surround decoder, the Dolby
Digital (AC-3) decoder or the DTS decoder precisely
reproduces sounds and sound effects of a source
encoded with the Dolby Surround or the DTS. The
realization of a highly efficient decoding process improves
crosstalk and channel separation and makes sound
positioning smoother and more precise.
This program ideally simulates the multi-surround speaker
systems of the newest film theater. The digital sound field
processing and the Dolby Surround decoding or the DTS
decoding are precisely performed without altering the
originally designed sound orientation. The surround
effects produced by this sound field fold the viewer
naturally from the rear to the left and right and toward the
screen.
