The MCFx2 is our state variable ‘MCF’ filter made double. It features 2 identical classic analog 3 pole filter cores each with Low, High and Band Pass (or Notch) outputs. Direct and voltage control is provided for both filter cut offs and resonance.

Two switches allow the filters to function as one, with the ‘Feed’ switch internally routing audio from one filter to the other in series and the ‘Link’ switch linking the cut off controls for both filter cores.

MCFx2 expands on the great sounding MCF filter (previously available only as part of the System Coupe) to offer both serial and parallel functionality for stereo operation, dual peak, tighter slopes and other complex filtering set ups.
