Cut Filters
DE-ESS THRESHOLD
This control determines the level
in dBu that the upper frequen-
cies (as set by the
FREQUENCY
control) must exceed to activate
de-essing. A setting of
-50 de-
esses everything, while at
20 no
de-essing occurs. The THRESHOLD
LED illuminates when the de-
esser threshold has been reached
and the de-esser is active.
De-esser
DE-ESS RATIO switch
This sets the amont the sliding
band filter will “slide” for a given
amount of sibilance. The ratio
settings are adjustable from
MILD
(a little de-essing), NORM (moder-
ate de-essing), and MAX (heavy
de-essing).
LOW CUT FILTER
This control rolls the low frequen-
cies off at a rate of 12 dB per
octave. The frequency designator
(10 Hz to 250 Hz) is the corner
frequency at which the low end
starts to roll off. Turned all the
way counterclockwise, the low
cut filter is essentially out of the
circuit.
BYPASS switch
This allows de-essing to be
bypassed for easy comparison
between de-essed and non-de-
essed signal.
DE-ESS FREQUENCY
This control selects the upper
range of frequencies that the de-
esser circuit responds to. A
setting of 700 Hz is for extreme
de-essing, while 9 kHz provides
very light de-essing.
HI CUT FILTER
This control rolls the high fre-
quencies off at a rate of 12 dB
per octave. The frequency desig-
nator (3 kHz to 40 kHz) is the
corner frequency at which the
high end starts to roll off. Turned
all the way clockwise, the high
cut filter is essentially out of the
circuit.
