The Circuit Slices CS031 VCF module is a quality, four pole, voltage-controlled, low pass filter with
voltage-controlled resonance for the Eurorack synthesizer format sold at an affordable price.
Specifications & Features for the CS031 VCF
High-quality, yet affordable Eurorack low pass VCF
Based on the SSI2144 chip from Sound Semiconductor (new version of the classic SSM2044)
Four-Pole Low Pass
Differential inputs
Large Sweep Range – Typical 20,000 to 1
Low control feedthrough
(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
One output (OUT)
Five front-panel controls (FREQUENCY, RESONANCE, SIG 2, CV 2, 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 the module very affordable
Includes power cable, case screws, and shorting jumpers
Setup & Installation
Route the ribbon-cable power connector to your power bus and mount the panel into your case using
the supplied screws. While this module does include reverse power protection, please be careful
making the connection to your power bus
and double check your connection before applying power.
