AC-3 Effects and Parameters
5.1 Logic 7
5.1 Logic 7 combines all the features of Dolby Digital AC-3 with
enhancements 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-equalizer 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.

Dolby Digital
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 MC-1.
