Because of the variation in the process, we developed the ABD40J to help restore the low
frequencies lost during the process, but the acoustics of various environments are different.
Sweep control allows you to select a center frequency (the frequency most affected) be-
tween 27Hz - 63Hz
Width control then allows you to control the range of other lters centered on the frequency
Sweep.
Bass Processor: Contains circuitry that accurately recreates low frequency information
back into the signal.
L.E.D. Indicators: The three L.E.D. indicators ash when the low frequency equalization
circuit is activated and with increased Sound Pressure Level.
Remote Mount Control: This is a wired level control that allows the user to adjust the pro-
cessor from a remote location.
