PCM Effects and Parameters
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 noticeable if the sur-
round 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 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.

the dialog in the center. Mono Logic
