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.
