5.1a UL2Cin, 5.1a SurEX, & 5.1a (continued)
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 parameter 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
surround 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 3-32 for more
information.
The 5.1a THX SurEX listening mode
The 5.1a THX SurEX listening mode is available when both side and
rear speakers are present and THX surround EX decoding is active.
THX Surround EX decoding is activated when the SURROUND EX
parameter is set to ON.
When THX Surround EX decoding is activated Matrix decoding is
applied to derive three surround channels from 5.1-channel analog
sources.
The 5.1a THX listening mode
The 5.1a THX listening mode is available when neither THX Ultra2
nor THX Surround EX decoding is active.
