Koma Elektronik SVF-201 Filter Module

The SVF-201's filter circuit is built up with optical parts (vactrols).

Inputs and Outputs

The SVF-201 comes with CV inputs with attenuators for Cutoff, Resonance and Select/Mix Out, where the last one allows the user to sweep between the three different filter characteristics. The module also has adjustable gain up to +6dB, which gives the user to opportunity send a (slightly) overdriven signal into the circuit which results in MS20-like filter sweeps.

The unit comprises four audio outputs that can be used independently of each other at the same time, a High Pass, Band Pass, Low Pass and the unique CV’able Mix Out. The Mix Out out lets you sweep continuously through the other three outputs by means of a knob and control voltage.

Build and layout

Behind the Cutoff knob there are 2 small LEDs fitted that give a glow. The SVF-201 uses parallel mounted PCBs so it can be used in skiffs as well as in big cases, the total depth is less than 40 mm. 

Specifications:

General

– Size: 3U, 12HP (60,60mm)

– Interface: 2mm white powder coated aluminum front plate + silkscreen printing

Technical

- 4 audio outputs:

• Low Pass
• Band Pass
• High Pass
• Mix Out

- Audio input with attenuator / adjustable gain

- 3 CV inputs:

• CV input for Cutoff with attenuator
• CV input for Resonance with attenuator
• CV input for Mix Out with attenuator 
  (The Mix Out attenuator acts as a normalized CV source if nothing is patched into the Select CV input)

- Large 30mm, full aluminum knob for Cutoff with white backlight (a jumper on the PCB lets you turn it off)

- Large 20mm, full aluminum knob for Resonance
