Adaptive Decorrelation
In a movie theater, a large number of surround speakers help create an
enveloping surround sound experience. If a home theater only has two
sidewall surround speakers, the surround speakers may sound similar to
headphones lacking spaciousness and envelopment. Surround sounds
will also collapse toward the closet speaker as you move away from the
middle seating position. Adaptive Decorrelation slightly changes one
surround channel’s time and phase relationship with respect to the other
surround experience as in a movie theater using only two speakers.
ASA (Advanced Speaker Array)
ASA is a proprietary THX technology which processes the audio on the
two side and two back surround speakers for the optional surround sound
experience. When you set up your home theater system using eight
speaker outputs (Front Left, Center, Front Right, Surround Right,
Surround Back Right, Surround Back Left, Surround Left, and
Subwoofer), be sure to go to the THX Audio Setup screen and choose
the setting that closely corresponds to the back speaker spacing. This will
reoptimize the surround sound field. ASA is used in three modes: THX
Select2 Cinema, THX Select2 Music and THX Select2 Games.
