THX
As with the PLII THX DSP preset, THX re-equalises the signals to suit
domestic listening conditions, and applies frequency-response correction
and decorrelation to the surround channels to make the surround sound
more realistic. It can be used whether or not your other equipment is THX
approved.
THX DSP preset parameters
Parameter
Surr. Rear
EX, THX EX, EZ, THX Ultra2, and THX Music
These presets are available if you have four surround speakers, and use
ProLogic II decoding on a 5.1 source to create an additional two channels
for the side speakers.
The EX and THX EX presets use a variant of ProLogic II to increase the
directionality of the surround with movie soundtracks. They are
recommended for movies marked as being recorded in Dolby Surround EX.
The EZ preset is a Meridian variation of EX that allows the steering to be
varied from 7 (full EX steering) to 0 (no steering). Reducing the steering

What it changes
Allows you to specify how DVD Audio channels
3+4 should be interpreted: Off ignores them, 5.1
and 7.1 use them for centre and LFE, Side uses
them for the side speakers, and High uses them
for ceiling speakers. 7.1 differs from 5.1 in that it
duplicates the surround channels in the side
speakers.
Allows you to specify which speakers the
surround channels should be sent to in a system
with four surrounds.
The cutoff of high frequencies from the rear
surrounds.
The cutoff of high frequencies from the side
surround.
The relative level of the LFE bass channel.
What it changes
Switches the surround signal between the
