Description

AS3320 / CEM3320 filter adaptation.

The Pro VCF is a faithful adaptation of a well-known 4-pole synthesizer filter in Eurorack.

The core of this design lies an Alfa AS3320 filter chip based on the original Curtis.

Countless synthesizers used the 320:
$Sequential Pro One, Prophet 5 rev 3, Drumtraks, Crumar Trilogy, Stratus, Elka Synthex, some Fairlight CMI, Linndrum, Oberheim OB-8, OB-Xa, PPG Wave 2

At full resonance the Pro VCF can self-oscillate.

FEATURES

- Two selectable filter slopes: original 24 db/oct, and 12 db/oct.
- Two voltage controlled input jacks for frequency CUTOFF w/ signal attenuators.
- A voltage controlled input jack for RESONANCE w/ a signal attenuator.
- Two signal input jacks w/ individual attenuators. At full clockwise, these inputs can overdrive the filter from most eurorack oscillators and audio sources.
