Proto VCF/A carries the Enigiser filter and VCA character into a clean eurorack module format with skiff-friendly depth and two panel finishes. Circuit based on an original Enigiser prototype kindly loaned by Anthony Linell of Northern Electronics.
VCF:
- Unique configuration with 3x4 filter moder
- 2x audio input with drive
- 2x cutoff CV attenuator inputs
- 1x cutoff CV input, tunable to 1v/oct
- VCF output normalized to VCA input.
VCA:
- 1x audio input with drive, normalized from VCF output
- 2x CV input. CV1 knob adds offset for drone etc.
- CLIP switch for old/new revision Enigiser diode setting adjusting drive character.
