Low Pass VCF (4 Pole)

The CS031 VCF is a quality, four pole, voltage-controlled, low pass filter with voltage-controlled resonance.

This great little module produces the much sought after sound of many vintage synthesizers through the use of a new version of a classic VCF chip.

Circuit slices is known for quality builds at very affordable prices -- this one is just in from the factory! Brand new.

Four-Pole Low Pass
Differential inputs
Large Sweep Range – Typical 20,000 to 1
Low control feed-through
(See the SSI2144 data sheet for complete specifications for this chip)
Two signal inputs: Sig 1 and SIG 2 (SIG 2 with an attenuator)
Two Frequency CV inputs: CV 1 and CV 2 (CV 2 with an attenuator)
One Resonance CV input: CV RES, with an attenuator
Five front-panel controls (FREQUENCY, RESONANCE, SIG 2, CV2, CV RES)
Frequency CV factory-tuned to 1V per octave
Small depth: 33 mm (1.3”) with power cable plugged in (great for use in “skiff” cases)
Panel width: 8 HP
Low power consumption:
+12V @ 15mA
-12V @14mA
Reverse power protection
Modern SMT manufacture and single PCB design makes this module very affordable.
Includes power cable, case screws, and shorting jumpers.
