Rob Papen Predator - Filter Modes Explained

24
Filter mode
- Bypass
The filter is bypassed and the sound passes through unaffected.
- 6dB LowPass
Low frequencies pass through this filter and frequencies above the Cutoff frequency are reduced by 6dB per
oct ave.
For example: a frequency 2000Hz is 6dB softer in volume if the Cutoff frequency is set to 1000Hz.
- 6dB HighPass
High frequencies pass through this filter and those below the Cutoff frequency are reduced by 6dB per
octave.
The filter is open if the C utoff frequency knob is fully turned left.
- 12dB LowPass
Low frequencies pass through this filter and those above the Cutoff frequency are reduced by 12dB per
octave.
- 12dB HighPass
High frequencies pass through this filter and those below the Cutoff f requency are reduced by 12dB per
octave.
The filter is fully open if the Cutoff frequency control knob is fully turned left.
- 18dB LowPass
Low frequencies pass through this filter and those above the Cutoff frequency are reduced by 18dB per
octave.
- 18 dB HighPass
High frequencies pass through this filter and those below the Cutoff frequency are reduced by 18dB per
octave.
The filter is fully open if the Cutoff frequency knob is fully turned left.
- 24dB LowPass
Low frequencies pass through this filter and those above the Cutoff frequency are reduced by 24dB per
octave.
- 24dB HighPass
High frequencies pass through this filter and those below the Cutoff frequency are reduced by 24dB per
octave.
The filter is fully open if the Cutoff frequency knob is f ully turned left.
- 12dB BandPass
This filter mode is a combination of 12dB LowPass and 12dB HighPass filters.
Only those frequencies near to the filter Cutoff frequency pass through (a band of frequencies), the
resonance (Q) , controls the width of this band so that low & high frequencies are removed.
- 24dB BandPass
This filter mode is a combination of a 24dB LowPass and 24dB HighPass filter.
Only those frequencies near to filter Cutoff frequency pass through (a band of frequencies), the resonance
(Q) controls the width of this band, so low & high frequencies are removed.
- 12dB Notch
Those frequencies near to the filter Cutoff frequency are reduced in volume (12dB), the resonance controls
the width of this removal region.
- 24db Notch
Those frequ encies near to the filter Cutoff frequency are reduced in volume (24dB), the resonance controls
the width of this removal region.
