PCM Effect Parameters

Mono Enhance takes a monaural soundtrack and sends music and
sound effects to the sides and rear through a room simulator mode while
keeping the dialog in the center.

5 SPEAKER ENHANCE simulates 7 speaker playback through a 5
speaker system, providing a heightened sense of spaciousness and
envelopment without extra speakers. This enhancement is most notice-
able if the surround speakers are positionned directly to the side of the
listening position, or if the listening position is located against the rear
wall.
Note that, although this provides very convincing improvement to a 5
speaker system, it is not a substitute for a properly set up and calibrated
7 speaker system. The difference is most noticeable when the listener
is seated to one side or the other of the calibration position.
ACADEMY FILTER is provided to recreate the proper tonal balance of
older monaural films that were recorded with much narrower and duller
frequency response than current films.
AUTO AZIMUTH is short for auto azimuth error correction/automatic
input balance. Auto Azimuth should be set to ON for films, and OFF for
music. When ON, special patented algorithms continually monitor the
input signal and adjust both the relative level and time offset of the two
channels to keep the dialog properly centered and special effects
properly localized. This automatic feature is the reason the unit does not
need an input balance control for Dolby Surround decoding.
BASS CONTENT allows you to modify the bass content for Mono,
Stereo or Binaural recordings. The BINAURAL setting turns the rear
level parameter off and activates special low-frequency compensation.
This feature is offered specifically for true binaural recordings made with
a dummy head.
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.
