Music Logic
This film sound mode reproduces musical material with maximum separa-
tion at all times, whether or not directional material is being steered. In
addition, Logic 7 uses intelligent steering to extract wide bandwidth stereo
surround channels. If both side and rear speaker pairs are available, signals
may be steered between the left side and left rear, or between the right side
and right rear. It is also possible for a signal to be steered fully to the rear
speakers, with the side surround speakers 6dB lower than the rears to
provide subjective rear imaging.
Logic 7 contains the re-equalizer feature of the THX Cinema effect, as well
as Lexicon's proprietary vocal enhancement feature. The combination of
stereo surround information during music and decorrelated effects, with
discrete steering to the sides and rears, gives Logic 7 unrivaled performance
on matrix encoded films.
