Surround sound

Sound that consists of three elements: direct sound,
early reflected sound (early reflections) and
reverberative sound (reverberation). The acoustics of
the surrounding space affect the way these three sound
elements are heard. Surround sound combines these
sound elements in such a way that you actually can
sense the size of the venue, as well as its type.

Digital Cinema Sound
This is the generic name of the surround sound
produced by digital signal processing technology
developed by Sony. Unlike previous surround sound

Digital Cinema Sound is designed specifically for the
enjoyment of movies.

Dolby Digital

This sound format for movie theaters is more advanced
than Dolby Surround Pro Logic. In this format, the rear
speakers output stereo sound with an expanded
frequency range and a sub woofer channel for deep
bass is independently provided. This format is also
called "5.1" because the sub woofer channel is counted
as 0.1 channel (since it functions only when a deep bass
