Dolby Digital
One has been familiar with it from the cinema for some years: just the sound invites one to step into the film. The three dimensional sound gives one the impression of sitting right there in the middle of the action.
This technology is now available for the HomeCinema and makes it into something really worth "living". The so called 5.1-system is used, that means 5 full-range boxes (right + left front, a centre box, for each a surround right + left) as well as a sub-woofer. Together, all of them guarantee an optimal sound.
