• Listening mode name differs depending on the encoding
present in the input source, the SURROUND EX parameter
setting, and the speaker setup.
– The 5.1 THX ULTRA2 listening mode is available when THX
Ultra2 decoding is engaged.
– The 5.1 THX SurEX listening mode is available when THX
Surround EX decoding is engaged.
– The 5.1 THX listening mode is available when neither THX
Ultra2 nor Surround EX decoding is engaged.
– The 5.1 THX ULTRA2 and 5.1 THX SurEX listening modes
cannot be activated unless side and rear speakers are
present.
Note:
The SDP-5 cannot automatically detect THX
Surround EX encoding in non-flagged 5.1-channel
Dolby Digital sources. A non-flagged source does not
include information in the input signal that identifies
THX Surround EX encoding.
