doepfer System A - 100 Distortion / Waveshaper A-136

1. Introduction
Module A-136 is a distortion and waveshaping mo-
dule with extensive control possibilities. Different set-
tings of 5 distortion/waveshaping parameters enable a
lot of very complex and extreme waveform modificati-
ons.
The incoming audio or cv signal is divided into 3
sections: original, positive and negative component.
For the positive and negative component, clipping
levels (L) are defined. Only voltages beyond this level
effect the output signal. For each of the three sections
the positive or negative amplification (A) can be adju-
sted.
External control voltages can be used to alter both
clipping levels so that dynamic waveform changes are
possible.
The range of modification goes from simple soft or hard
clipping to completely altered waveforms where the
original signal is no longer recognizable.
Typical applications are audio distortion, and waveform
modification for audio signals as well as for control
voltages (LFO, ADSR, random etc.).

3. Controls
1 A
Control 1 defines the amplification A of the original
signal. The range of the amplification factor is about
-4...+4. This means that one can obtain actual
amplification (range +1...+4), or attenuation (range
0...+1) or even inversion of the original signal (range
-4...0). The table below shows the approximate
assignment of some control settings and the
corresponding amplification factors:

factors

Controls 2 and 3 adjust the positive (+L) and
negative (-L) respectively.clipping levels
In the positive signal section only signal voltages
above the positive clipping level +L are affected by the
amplification control +A.
In the negative signal section only signal voltages
below the negative clipping level -L are affected by the
amplification control -A.
