4-pole high-pass and low-pass VCFs on SSI2140

Nonlinearcircuits · 8 HP · 3U

Panel · 40.6 × 128.5 mm

Description

Two SSI2140 filters: a 4-pole high-pass and a 4-pole low-pass, each with voltage-controlled cutoff and Q. The high-pass output feeds the low-pass input's switch, so the pair makes a band-pass VCF; otherwise they are two separate filters.

Key features

  • High-pass: IN HP, FR CV, Q CV in, HP OUT; HI-PASS FREQ, FREQ CV, Q, Q CV
  • Low-pass: IN LP, FR CV, Q CV in, LP OUT; LO-PASS FREQ, FREQ CV, Q, Q CV
  • 8 HP; Nonlinearcircuits publishes no current draw, depth or assembled price (it sells the DIY PCB and panel), and ModularGrid lists none
