RUMBLE FILTER

Rumble
Filter is a
high
pass filter
in
cascade
with
a
low
pass
filter, fourth
order
(24dB
per
octave). The
high
pass
filter is
good
for eliminating turntable rumble. The
low
pass
filter is good
for eliminating hiss. Alternatively, these filters can
be
used
in
a feedback
routing
with
any
other
effect.
The parameters available for the Rumble Filter are:
01-Mix
02-Volume
See the descriptions
under
the
Mix
and
Volume Parameters,
in
the beginning of this section. For
this algorithm
we
recommend
mid
values of
the
Mix.
03 - HighPass Fc
Range: 4 to
8000
Hz
Controls the boost or cut of the
high
pass
filter frequency
applied
to the
input
signal.
04 - LowPass Fc Range: 100 Hz to
16
KHz
Controls the boost or
cut
of the
low
pass
filter frequency
applied
to the
input
signal.
05 - Filter Gain Range: -48 to +48 dB
Because the cascade of high
pass
with
low
pass
causes
an
insertion loss, this
parameter
allows
you to boost the filtered
output
signal.
