Listening mode name differs depending on the encoding present 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 EX parameter is set to ON or when the SURROUND EX parameter is set to AUTO and a flagged 5.1-channel Dolby Digital source with THX Surround EX encoding is detected.

•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.
