DOLBY SURROUND AND DTS SURROUND

This unit is equipped with the Dolby Pro Logic decoder, Dolby Digital decoder and DTS decoder.

The unit and the centre and surround speakers (standard) assure full-scale home theatre sound. When playing back discs or video software that have been recorded in Dolby Pro Logic, Dolby Digital surround or DTS surround, astonishingly realistic sound surrounds the listener to create a new level of audio/visual entertainment.

Independent control of the five channels allows the listener to enjoy the same type of sound reproduction experienced in movie theatres. Voices are reproduced in the front and centre sound field, while ambient sounds like cars and crowds are reproduced on all sides of the listener for an incredibly lifelike audio/video experience.
