This Effect provides THX 5.1 Cinema enhancements for film soundtracks
recorded in the DTS format. This processing compensates for the acoustical
differences between large mixing theaters and the typically smaller home
environment. When SIDE and REAR speakers are selected in the SPEAKER
CONFIG menu, SURROUND EX is automatically set to ON for proper
decoding of Surround EX soundtracks.

Parameters
BASS ENHANCE derives stereo bass to provide low frequencies that are
noticeably less localizable and more spacious in the playback room.
Note that results will vary depending on room acoustics and the low
frequency capacity of the surround speakers. As side and/or rear speakers
are used for bass enhancement, the effectiveness is improved with speakers
capable of reproducing reproducing low frequencies (LARGE). Using
speakers that are not capable of producing low frequencies (<80Hz) may
cause damage to them.
CENTER MIX adjusts the level of the center channel applied to the two-nnel
downmix. The appropriate value for film is 16. The appropriate value for
music is 11.
CENTER DLY SAMPLES adjusts the time offset of the center channel. The
appropriate value is +0 unless you know that the center channel is not
properly timed, as well as the amount by which it is off.
MASTER LEVEL adjusts the output level of the downmix. This control
should be set to +5dB unless the LFE is very heavy, in which ase the level
should be reduced.
LFE MIX LEVEL allows separate level attenuation of the LFE channel,
which is ultimately mixed to the subwoofer output. As the bass from as
many as five other channels is added to the LFE, it can significantly raise
subwoofer output levels — and create the risk of damage to a system.
Careful adjustment of this parameter will allow you to achieve proper tonal
balance and reduce the risk of damage.
