THX Founded by George Lucas, THX develops stringent standards that ensure
movies are reproduced in movie theaters and home theaters just as the direc-
tor intended. THX Modes carefully optimize the tonal and spatial character-
istics of the soundtrack for reproduction in the home-theater environment.
They can be used with 2-channel matrixed and multichannel sources. Sur-
round back speaker output depends on the source material and the selected
listening mode.
•THX Cinema
THX Cinema mode corrects theatrical soundtracks for playback in a home
theater environment. In this mode, THX Loudness Plus is configured for
cinema levels and Re-EQ, Timbre Matching, and Adaptive Decorrelation
are active.
•THX Music
THX Music mode is tailored for listening to music, which is typically mas-
tered at significantly higher levels than movies. In this mode, THX Loud-
ness Plus is configured for music playback and only Timbre Matching is

THX Games mode is meant for spatially accurate playback of game audio,
which is often mixed similarly to movies but in a smaller environment. THX
