1. Introduction

Module A-106-1 is an unique low/high pass filter and has it's

origin in our experiments to built a MS20 filter clone. In

contrast to other filter designs it has different audio inputs

for low and high pass, but only one audio output. The type

of filter (12dB low pass, 6dB high pass or any mix) is

defined by the shares of the audio signal fed to the

corresponding inputs. Even two different audio signals can

be used as low and high pass input. A special feature is the

polarizer at the high pass input that allows to add/subtract

the high pass to/from the low pass share, leading to pseudo

band pass and notch responses (details concerning pseudo

in the next chapter).

Another special feature are the clipping controls, which

allow independent adjustment of the positive and negative

clipping level. The resonance goes up to self-oscillation, but

with a clearly different behaviour than on other filters. At

certain resonance and clipping settings the self-oscillation

generates rectangle or short sawtooth shaped pulses.

In general the A-106-1 is a very strange and awesome filter

and far away from being perfect (e.g non-linear control

scale, self-oscillation with all sorts of waveforms except

sine, a lot of roaring, rattling, noise or other unpredictable

sounds at high distortion and resonance settings, high

distortion or audio level overrides the resonance, significant

CV feedthrough …). But the A-106-1 has a lot of character –

probably much more than any other filter of the A-100 – and

is able to generate filter sweeps which are not possible with

any other filter.
