MU All Pass Filter 115

MU All Pass Filter 115
MU All Pass Filter 115

The voltage controlled 4-pole all pass filter passes all frequencies but creates a phase shift as the cut-off frequency is swept. Used as a basis in phase shifter modules like our phaser 149.

  • Resonance potentiometer control with external CV control, self-oscillation at around 85% resonance


  • Supply voltage +/-15Vdc (Uses included in-line voltage regulator module with both MOTM and MU headers) 
  • Supply current  +10mA / -14mA
  • Waveform levels +/-5V
  • Frequency range: 10Hz to 8kHz with no external CV applied
