72 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 low end rumble. The low pass filter is good
for eliminating hiss. The EFFECT MIX FX-1 and FX-2 FILTER parameters can be routed into the
effect with different Dry/Wet mixes. For this algorithm, we recommend mid value Mixes.
HIGH FC Ranges: 4 to 8000 Hz
Controls the boost or cut of the high pass filter-frequency applied to the input signal.
LOW FC Ranges: 100 Hz to 15 KHz
Controls the boost or cut of the low pass filter-frequency applied to the input signal.
GAIN Ranges: -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.
73 VAN DER POL FILTER
VAN DER POL FILTER adds synthetic high harmonics to the input signal, brightening the
overall sound. This algorithm is most often used in the studio for vocalists, but feel free to
experiment with this algorithm using your favorite instrument as well. This algorithm features
prominent transient enhancement that makes it ideal for “plucked” sounds. The filter in this
algorithm operates on the signal prior to enhancement. Set the filter to enhance the-frequency
region that you desire. Then use the EFFECT MIX FX-1 parameter to mix the enhanced signal
with the dry signal. For this algorithm we recommend mid values of the Mix.
HIGH FC Range: 4 to 8000 Hz
Controls the boost or cut of the high pass filter-frequency applied to the input signal.
LOW FC Range: 100 Hz to 15 KHz
Controls the boost or cut of the low pass filter-frequency applied to the input signal.
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.
