Kilpatrick Audio K6501 Philter Euorack Module

The Kilpatrick Audio K6501 Philter Euorack module takes the filter design of their Phenol Patchable Analog Synthesizer and adapts it for Eurorack systems.

The Kilpatrick Philter offers low-pass, band-pass and high-pass outputs simultaneously. Each output contains a signal indicator showing when that output is active. Philter has the same tone and range of control as the Phenol filters in a compact package.

Features:

  • Eurorack (3U) form factor – 8HP width
  • 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

Pricing and Availability

The Kilpatrick Audio K6501 Philter Euorack module is available now for US $225.
