Parameter ranges and resolutions:
Type
The available filter types.
FRQ Filter frequency (center/corner frequency),
adjustable from 20 Hz to 20 kHz.
On the top right of the «Frequency/FRQ» input
field, the increment is displayed as an octave
value. When you tap the field for the first time,
the frequency increment is set to 1/6 octave.
When you tap the field again, you can toggle
between 1/6 and 1/96 octave increments.
To confirm the set frequency, press the
encoder.
Q
BW
Q of the filter, adjustable from 0.5 ... 25 in
10 % steps.
In addition, the resulting bandwidth (BW) is
displayed as a value (2.0 ... 0.04 octaves) in
a non-editable Information field below the Q
Input field.
Slope
Slope can be set to 6, 12, 18 or
24 dB/octave.
Gain Gain, adjustable from –18 dB to +12 dB in
