in the input source, the SURROUND EX parameter setting, and the
speaker setup. The table below indicates the conditions in which
THX Ultra2 and THX Surround EX decoding are engaged.
• The 5.1 ULTRA2 listening mode is available when THX
Ultra2 decoding is engaged.
• THX Ultra2 decoding is engaged when the SURROUND EX
parameter is set to OFF or when the SURROUND EX parameter
is set to AUTO and a non-flagged 5.1-channel Dolby Digital
source with or without THX Surround EX encoding is detected.
• The 5.1 SurEX listening mode is available when THX
Surround EX decoding is engaged.
• THX Surround EX decoding is engaged when the SURROUND

• The 5.1 Ultra2 and 5.1 SurEX listening modes are not
available unless both side and rear speakers are present.
• The 5.1 listening mode is available when neither THX
Ultra2 nor THX Surround EX decoding is engaged.

The MC-12 cannot automatically detect THX
Surround EX encoding in non-flagged 5.1-channel
Dolby Digital sources. A non-flagged input source
does not include information in the input signal that
identifies THX Surround EX encoding.
