Rane VP 12, Manual

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.
