The table below indicates the conditions in which THX Surround EX
and THX Ultra2 decoding are engaged.

THX Surround EX decoding is engaged when the SUR-
ROUND EX parameter is set to ON, or the SURROUND EX
parameter is set to AUTO and a flagged 5.1-channel Dolby
Digital source with THX Surround EX encoding is detected.

THX Ultra2 decoding is engaged when the SURROUND EX
parameter is set to OFF, or 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.

Listening mode name differs depending on the encoding
present in the input source, the SURROUND EX parameter
setting and the speaker setup.

The THX ULTRA2 listening mode is available when THX
Ultra2 decoding is engaged.

The THX SurEX listening mode is available when THX Sur-
round EX decoding is engaged.

The THX listening mode is available when neither THX
Ultra2 nor Surround EX decoding is engaged.

The THX ULTRA2 and THX SurEX listening modes cannot be
activated unless side and rear speakers are present.

Note:

The AV1 cannot automatically detect THX Surround EX encoding
in non-flagged 5.1-channel Dolby Digital sources. A no flagged
source does not include information in the input signal that iden-
tifies THX Surround EX encoding.
