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.
