THX
As with the PLIIx THX DSP preset, THX re-equalises the signals to
suit domestic listening conditions, and applies frequency-response
correction and decorrelation to the surround channels to make the
surround sound more realistic. It can be used whether or not your
other equipment is THX approved.
PLIIx Mov6, THX Surround EX, PLIIx Mus6, THX Ultra2
Cinema, and THX Music
These presets are available if you have four surround speakers. They
use Dolby Pro Logic IIx, Dolby Surround EX, and THX Ultra2 Cinema
processing to generate multiple signals for larger home theatres.
PLIIx Mov6 uses extended PLII technology from Dolby to generate
four surround signals from traditional multichannel source material
like Dolby Digital 5.1. It is intended for use with movie soundtracks.
PLIIx Mus6 also creates four surround signals; it is intended for
multichannel music playback from sources such as DVD-A or SACD
music discs.
THX Ultra2 Cinema and THX Music use a THX proprietary process
called advanced speaker array to provide a mix of ambient and
directional surround sounds using four surround speakers. Optimum
performance of THX Ultra2 Cinema and THX Music is produced
when the two rear speakers are placed close together behind the
listening position. THX Ultra2 Cinema is recommended for movie
soundtracks that are not Dolby Surround EX encoded, and THX
Music is recommended for listening to multichannel music.
