K6501 Philter - 8HP


The Philter, from Kilpatrick Audio, is the filter that was released in their flagship standalone modular synth, the Phenol. From the highly positive response that the Phenol received, it seemed only logical to produce the filter itself for any Eurorack modular system. With high resonance, the Philter can reach dirty overdrive with ultimate phatness. It is a multimode filter, with Lowpass, Bandpass, and Highpass outputs, with each output monitored by an LED. Don't be fooled by its tame look, this Philter can get massive. 


  • Filter circuit inspired by PHENOL and true to the sound and range of control
  • Simultaneous low-pass, band-pass and high-pass outputs
  • Unique two-pole design with special resonance limiter for huge peaks without oscillation
  • Control over cutoff, resonance and FM level (voltage control of frequency)
  • All inputs and outputs are tolerant of +/-12V
  • All outputs drive 10Vp-p with 1K output impedance
