The Filter block
D-Pole’s Filter block covers the frequency
range between DC and frequencies higher
than 17000 Hz. It offers Resonance until self-
oscillation, different filter types and a selecta-
ble Slope. Here’s a description of its parame-
ters:
Cutoff 0 Hz... > 17000 Hz
Cutoff controls the Cutoff frequency of the filter.

Turn Cutoff to the left to lower the Cutoff frequency.
 Turn Cutoff to the right to increase the Cutoff frequency.
Depending on the filter type, certain frequencies above or below the Cutoff frequency
are filtered. Find information on which frequencies are filtered in the table above.
Resonance 0%...100%
Resonance controls the emphasis of signals around the Cutoff frequency.

Lower Resonance values will result in no or a slight emphasis on the signal around
the Cutoff frequency
 Higher Resonance values will result in a strong emphasis on those frequencies. Ex-
tremely high Resonance settings will cause the filter to self-oscillate and create a sine
wave tone.
Please note that – if Resonance is set to a value of 100% – this tone can easily cause
clipping. Should this happen to you, lower Resonance to 99% or adjust the output vo-
lume in the Amplifier block.
Type Low, High, Band, Notch, Resonator
Use this parameter to select the filter type. This determines which frequencies may pass
through the filter unchanged and which are filtered out.
Click on an “LED” or its name to select one of the following filter types:

Low : All frequencies above the Cutoff frequency are filtered.
 Band : All frequencies above and below the Cutoff frequency are filtered.
 High : All frequencies below the Cutoff frequency are filtered.
 Notch : All frequencies near the Cutoff frequency are filtered. Other frequencies re-
main unchanged.
 Resonator : All frequencies may pass the filter. At Cutoff frequency, a feedback is
being created that you can control by changing the Resonance parameter.
