PCM Effect 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 positioned 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.
