This unit is equipped with the Doiby Pro Logic decoder and aiso
supports the Doiby Digitai decoder with the 5.1 ch output
terminais.
The unit and the center and surround speakers (standard) assure
fuii-scaie home theater sound. When playing back discs or video
software that have been recorded in Dolby Pro Logic or Dolby
Digital Surround, astonishingly realistic sound surrounds the
listener to create a new level of audio/visual entertainment.

theaters. Voices are reproduced in the front and center sound
field, while ambient sounds like cars and crowds are reproduced

system’s output to match the characteristics of your listening
space.
