Logic 7; Dolby Digital - Lexicon DC-1 Owner's Manual

DC-1 Version 4 Digital Controller
5.1 Logic 7 combines all the features of Dolby Digital AC-3 with enhance-
ments by Lexicon and LucasFilm. This effect uses Logic 7 matrix technology
to enhance the steering between the side speakers and the rear speakers, so
sounds intended to come from behind the listener actually do come from
behind. This effect also includes the adaptive decorrelation and re-equal-
izer features of THX 5.1.
5.1 Logic 7 provides the ultimate in film reproduction. It brings out all the
increased excitement and spaciousness a 7 channel speaker system can
produce.

The Dolby Digital effect decodes Dolby AC-3 encoded soundtracks. Unlike
analog Dolby surround decoding, Dolby Digital uses five discrete full-
range channels and a sixth dedicated, Low Frequency Effect (LFE) channel.
In this effect, any rear speakers present are connected in parallel with the
side speakers. This is the standard Dolby Digital decoder. It does not
include the enhancements by Lexicon or LucasFilm which are available
with other AC-3 effects in the DC-1.
