RUMBLE FILTER
126
00 - 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.
