Mono Logic Parameters
44
Mono Logic 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.

ROLLOFF regulates the treble cut in the side and rear channels. The optimal
setting for this parameter will vary widely with the age, quality, and
condition of the source material.
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.
MAIN LEVEL controls the level of the mono signal that is reproduced by the
main speakers. When a center speaker is part of the configuration many
films may sound better when this control is set between 6-12. This spreads
the film sound out around the screen and can be more pleasant than
restricting the dialog and much of the other film sound to the center speaker.
SUB BASS BOOST boosts or cuts the subwoofer output level. Although the
normal subwoofer level is set during the calibration procedure, with some
recordings it may be desirable to increase or decrease this deep bass level.
EFFECT LEVEL adjusts the loudness of the side and rear speakers. When
there are no side speakers, it adjusts the amount of ambient signal mixed
into the main loudspeakers.
