About THX

The THX technologies are explained below.

THX Cinema processing

THX is an exclusive set of standards and technologies established by THX Ltd. THX grew from George Lucas’

personal desire to make your experience of the film soundtrack, in both movie theatres and in your home theatre,

as faithful as possible to what the director intended. Movie soundtracks are mixed in special movie theatres

called dubbing stages and are designed to be played back in movie theatres with similar equipment and condi-

tions. This same soundtrack is then transferred directly onto Laserdisc, VHS tape, DVD, etc., and is not changed

for playback in a small home theatre environment. THX engineers developed patented technologies to accurately

translate the sound from the movie theatre environment into the home, correcting the tonal and spatial errors

that occur. On this product, when the THX indicator is on, THX features are automatically added in Cinema

modes (e.g. THX Cinema, THX Surround EX).

Re-Equalization

The tonal balance of a film soundtrack will be excessively bright and harsh when played back over audio equip-

ment in the home because film soundtracks were designed to be played back in large movie theaters using

very different professional equipment. Re-Equalization restores the correct tonal balance for watching a movie

soundtrack in a small home environment.

Timbre Matching

The human ear changes our perception of a sound depending on the direction from which the sound is coming.

In a movie theatre, there is an array of surround speakers so that the surround information is all around you. In

a home theatre, you use only two speakers located to the side of your head. The Timbre Matching feature filters

the information going to the surround speakers so that they more closely match the tonal characteristics of the

sound coming from the front speakers. This ensures seamless panning between the front and surround speakers.

Adaptive Decorrelation

In a movie theatre, a large number of surround speakers help create an enveloping surround sound experience,

but in a home theatre there are usually only two speakers. This can make the surround speakers sound like head-

phones that lack spaciousness and envelopment. The surround sounds will also collapse into the closest speaker

as you move away from the middle seating position. Adaptive Decorrelation slightly changes one surround chan-

nel’s time and phase relationship with respect to the other surround channel. This expands the listening position

and creates-with only two speakers- the same spacious surround experience as in a movie theatre.
