AC-3 Effects and Parameters
AC-3 Effect Parameters
AC-3 STATUS displays the current status of incoming AC-3 data. The
displayed items are not user adjustable.
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 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.
CENTER MIX adjusts the level of the center channel applied to the two-
channel downmix. The appropriate value for film is 16. The appropriate
value for music is 11.
COMPRESSION enhances the intelligibility of Dolby Digital material at
low volume levels (-6dB or lower). When set to AUTO, this control
automatically limits peak signals and boosts low level signals. The
amount of compression increases proportionately as volume is de-
creased. This is quite useful when listening to Dolby Digital soundtracks
at low output levels. When set to ON, full compression is applied,
regardless of volume.

CUSTOM
THX 5.1 (Including Surround EX)
This Effect provides THX 5.1 and Surround EX enhancements for film
soundtracks recorded in the Dolby Digital format. This processing
compensates for the acoustical differences between large mixing the-
aters and the typically smaller home environment. When SIDE and
REAR speakers are selected in the SPEAKER CONFIG menu, SUR-
ROUND EX is automatically set to ON for proper decoding of Surround
EX soundtracks.
