VCF 1 A-120

1. Introduction

Module A-120 (VCF 1) is a voltage controlled low-

pass filter, which filters out the higher parts of the

sound spectrum, and lets lower frequencies pass

through.

The Cut-Off Frequency determines the point at which

filtering takes effect. You can control this manually, or

by voltage control (filter modulation, for instance by

an LFO). Three CV inputs are available, and the sum

of the voltages from these affects the filter cut-off.

VCF1 is a co-called "transistor ladder" design, with a

cut-off slope of -24 dB/octave, as in various Moog

synthesizers. That’s what gives it its classic, legendary

Moog sound.

Resonance (or Emphasis) is adjustable all the way up

to self-oscillation - in which case the filter behaves like

a sine wave oscillator.
