AC-3 Effects and Parameters

Lexicon

THX 5.1

(Including Surround EX)

This Effect provides THX 5.1 Cinema 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. 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.

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 auto- matically limits peak signals and boosts low level signals. The amount of compression increases proportionately as volume is decreased. 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.
