About the THX Ultra ™ System
THX is an exclusive set of standards and technologies established
by the world-renowned film production company, Lucasfilms Ltd.
THX grew from George Lucas' personal desire to make your expe-
rience of the film soundtrack, in both movie theaters and in your
home theater, as faithful as possible to what the director intended.
Movie sound tracks are mixed in special movie theaters called
dubbing stages and are designed to be played back in movie the-
aters with similar equipment and conditions. The soundtrack cre-
ated for movie theaters is then transferred directly onto Laserdisc,
VHS tape, DVD, etc., and is not changed for playback in a small
home theater environment. THX engineers developed patented
technologies to accurately translate the sound from the movie
theater environment into the home, correcting the tonal and spa-
tial errors that occur.
Before any home theater component can be THX Ultra certified, it
must incorporate the THX technologies and also pass a rigorous
series of quality and performance tests. Only then can a product
features the THX Ultra logo, which is your guarantee that the
Home Theater products you purchase will give you superb perfor-
mance for many years to come.
