more detail).

5.1 Dolby/THX
This Effect provides THX 5.1 enhancements for film soundtracks
recorded in the Dolby Digital format. This processing compensates for
the acoustical differences between large mixing theaters and the
typically smaller home environment. In this effect the side and rear
speakers are driven in parallel when you designate the use of rear
speakers in the Speaker Configuration menu.
