The 5.1a THX UL2Cin listening mode
The 5.1a THX UL2Cin listening mode is available when both side
and rear speakers are present and THX Ultra2 decoding is active.
THX Ultra2 decoding is activated when the SURROUND EX param-
eter is set to OFF. When THX Ultra2 decoding is activated:
• Adaptive de-correlation is applied to increase the perceived
width of the listening space. De-correlation of the mono sur-
round channel increases the perceived width of the surround
field in home theaters.
• ASA processing is applied to signals sent to the rear speakers.
Refer to the ASA parameter description on page 3-35 for more
information.
