Dolby Surround
(11 Dolby Digital (Dolby Surround AC-31
Dolby Digital is the multr-channel drgital srgnal format developed by Dolby Laboratories.
Dolby Digital consists of up to "5.1" channels -front left, front right, center, surround left, surround right, and an additional channel exclusively
reserved for additional deep bass sound effects (the Low Frequency Effects - LFE - channel, also called the ",I " channel, containing bass
frequencies of up to 120 Hz),
Unlike the analog Dolby Pro Logic format, Dolby Digital's main channels can all contain full range sound information, from the lowest bass, up
to the highest frequencies - 22 kHz. The signals within each channel are distinct from the others, allowing pinpoint sound imaging, and Dolby
Digital offers tremendous dynamic range from the most powerful sound effects to the quretest, softest sounds, free from noise and distortion.
