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.
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.
