• To play Dolby Digital Surround EX-encoded software in 6.1 channels, it
is required to set the THX Surround EX mode to On or Auto.
Note that some of Dolby Digital Surround EX-encoded software does
not contain the identification signal. In this case, set the THX Sur-
round EX mode to On.
• Set the THX mode to Off when DTS-ES decoding is required.
• The THX operation is not activated with the 96k fs PCM signal.
• When Dolby Pro Logic II: Music is selected while THX Sur EX On,
THX Sur EX Auto or THX On is selected, the THX mode will be
switched Off.
• As long as Dolby Pro Logic II: Music is selected, switching the THX
mode does not produce any effect.
• Different THX modes can be selected for the different input devices.
The selected THX modes for the separate input devices are stored in
the memory.
