Module A-120 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..

Module A-119 (External Input / Envelope Follower) is designed to allow external audio signals to be integrated into the System A-100. It comprises a pre-amp, envelope follower, and comparator.The pre-amp has two inputs: an unbalanced input for line level signals, with a gain factor of from 0 to 20, ..

Module A-118 is (as you might have guessed) a noise and random voltage generator. It produces three types of signal: white noise, colored noise, and random voltage. The noise signal is generated 100% analog by amplification of the noise of a transistor. White and colored noise can be used as audio s..

Module A-117 (DNG) is a combination module, including a digital noise generator and an 808 source.The digital noise generator uses random sequences of square waves (18 step shift register with multiple feedback), whose rate can go from random clicks to noise. The colour of the noise is very differen..

Module A-116 provides voltage-controlled dynamic waveform modification of audio signals. It can produce new waveforms from the standard VCO shapes, and modulate these changes in real time. The signal first of all goes through an input amplifier, which can attenuate the signal as well as amplify it b..

Module A-115 is a four-way frequency divider. The frequency of a signal at the input is halved (half frequency = first sub-octave), quartered (1/4 frequency = second sub-octave), and so on. In this way, the DIVIDER produces four sub-octaves (F/2 down to F/16).At the output, the A-115 produces a summ..

Module A-114 contains two separate ring modulators. A ring modulator outputs the product (Multiplication X • Y) of the signals at inputs X and Y. It's similar to a VCA, but whereas a VCA only responds to positive voltages at the inputs (2-quadrant multiplication), the ring modulator responds to both..

Module A-113 is a new sound source that derives from an incoming pulse signal four so-called subharmonics (German: Subharmonische). The term subharmonics was introduced by Oskar Sala in connection with his so-called Mixtur-Trautonium. A subharmonic means  in t..

Module A-112 is the combination of a voltage controlled 8 Bit Sampler and a wavetable oscillator. On top of it the module is able to generate some special effects. A-112 was designed as an additional sound source with the typical sounds of the early 8 bit samplers and is not comparable with the mode..

Module A-111-3 is an extremely space-saving precision VCO/LFO with a 4HP panel only. Essentially it's the same basic circuit as the A-111-2 but with reduced features:triangle corefully analog designmin. 15 octaves pitch range in each mode (VCO/LFO):VCO mode: typ. 0.5 Hz - 20 kHz ..

Module A-111-2 is the successor of the obsolete High End VCO I A-111-1.Here are the most important features of the planned module:triangle coremin. 15 octaves pitch range (typ. 0.5Hz - 20kHz)perfect 1V/octave tracking over min. 10 octaves (typ. 20Hz - 20kHz)exponential frequency controls and in..

A-110-6 is a Trapezoid Thru Zero Quadrature VCO. The module is based on an idea by Donald Tillman from 2003 but has been revised for the use of modern electronic circuits (no OTAs/CA3280). Because of it's unique trapezoid core it's totally different compared to other VCOs. But the trapezoid cor..
