THX Surround EX
THX Surround EX allows 5.1-channel film soundtracks to be
encoded with an extra surround channel during the mixing
process. EX post-processing can be used with THX when
decoding a 5.1-channel Dolby Digital signal. The decoded
surround signals are matrixed to the four surround speakers
giving more detailed imaging behind the listener and bringing
more depth, ambience, and localisation than before.
EX post-processing is available with Digital THX preset:
Parameter Options What it changes
THX-EX On, Off, Auto Switches on or off the EX post-
processing. Auto automatically
detects bitstreams marked as
EX encoded *.
* Some EX-encoded discs may not be marked as EX encoded,
in which case select On rather than Auto.
Meridian EZ
Meridian have used their experience in developing algorithms for
multiple surround speakers to create a proprietary DSP
processing mode, called Meridian EZ. This is designed to give
an exciting spacious surround enhancement for non-THX
enhanced 5.1 sources, such as Dolby Digital and DTS.
EZ post-processing is available with the following DSP presets:
Digital, DTS, DTS Music, MPEG, and MPEG Music.
Parameter Options What it changes

processing on or off.
