122 Dual State Variable Filter

Description

This module contains two independent State Variable Filters with three filter modes available concurrently; high pass, band pass, low pass. Each filter type has its own output. 

Each SVF has three audio inputs, two frequency cutoff CV inputs, one resonance CV input. Tall trimmer potentiometer adjusting the levels. Frequency cutoff and resonance are controlled by 30mm slide potentiometers with subtle red LED’s.

The three outputs of SVF1 are normalised into the inputs of SVF2, so that incredible double filter sounds can be created. The module is based on the AS3320 chip, which will self oscillate at higher resonance settings.
