Dolby Surround And Dts Surround; Turning Surround On And Off - Aiwa AV-NW50 Operating Instructions Manual

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.
