doepfer System A - 100A-105 / A-122

1. Introduction

The modules A-105 and A-122 are voltage-

controlled low-pass filters, which filter out the higher

parts of the sound spectrum, and lets lower frequen-

cies pass through.

The cut-off frequencydetermines the point at which

filtering takes effect. You can control this manually, or

by voltage control (filter modulation, for instance by

an LFO). Two CV inputs are available. The cut-off

slope is -24 dB/octave.

Voltage controlled resonance: for both A-105 and

A-122, resonance can be controlled not just manually,

but by voltages as well, right up to self-oscillation. In

this case, the filter behaves like a sine wave oscillator.

The A-105is based on the special circuit SSM2044,

that was used in several devices of the companies

Korg (Polysix, Mono-Poly), Sequential Circuits

(Prophets, Pro-One), PPG, Fairlight, Emu and Kawai.

The circuitry of the A-122uses a Curtis CEM 3320

chip, and is very similar to the classic Oberheim filter

sound. Because of the different circuits the A-105 and

A-122 have considerably different sounds and even

sound different compared to the other filters (e.g.

A-120 Moog-type low pass, A-102 Diode Low Pass or

A-103 18dB low pass, A-124 Wasp filter).

As the functions and controls are the same for both

modules they are a combined in one manual.
