3320 High-Pass Filter (HPF)

3320 High-Pass Filter (HPF)

The 3320 High-Pass Filter (HPF) is a four-pole 24dB/octave design that uses the newly re-issued and authentic CEM3320 IC.


It is the perfect partner to go along side either our 3320 Low-Pass Filter (LPF) or 2144 Low-Pass Filter (LPF), to produce a band-pass filter.


On it's own however, it shines when used on percussion or drums, along with a wide range of other applications.



  • Four-pole 24dB/octave high-pass filter using the re-issued and authentic CEM3320 IC.
  • Manually controllable resonance and cutoff frequency.
  • Frequency range greater than audio range (> 20Hz to 20kHz).
  • Capable of self-oscillation i.e. producing a sine wave output.
  • Thermally compensated 1V/octave input.
  • Numerous modulation possibilities including FM and resonance CV inputs (0V to 10V input range).
  • Ergonomic design.
  • Hand-built and tested in the UK.



  • Format: Eurorack
