The A-131 module is the “sibling module” of the A-130 VCA. In contrast to this, it works with an exponential characteristic, but is otherwise identical. This makes it rather unsuitable for amplifying control voltages, but in most cases it is very suitable for amplifying audio signals. User interface Inputs: Outputs: Controls: A slightly “coloring” VCA … Read more
It’s hard to imagine even more VCAs in a small space than the A-130-8 allows. No fewer than eight independent, linear VCAs are housed here in just 6HP. And because there was still some space on the front panel, there are also sum outputs for inputs 1-4, 5-8 or for all inputs 1-8 together. So … Read more
The A-111-5 is not an oscillator in the traditional sense, but a complete mini synthesizer with VCO, VCF, VCA, ADSR and two LFOs. A “Dark Energy” (first generation) for the modular system! A lot of things here are patchable, but upon closer inspection you’ll see that some signal paths are exclusively internal. For example, there … Read more
The A-130 Voltage Controlled Amplifier is a (very well-equipped) linear VCA. The “sibling module” A-131 works with exponential characteristics, but is otherwise identically equipped. It has already been shown with the mixers A-138a (linear) and A-138b (exponential) that an exponential characteristic of the amplification comes closer to our psychophysiological feeling of a “perceived linear” volume … Read more
The module is small and interesting. A stripped down to two parameters but still flexible envelope generator with voltage control, hardwired to a linear VCA, plus a ducking function. The whole thing is also designed twice on only 8 HP. This is made possible by the new “Slim Line” format with slightly smaller buttons and … Read more
The A-132-3 Dual Lin. / Exp. VCA has two identical sub-modules. Both amplifiers can be switched independently between linear and exponential characteristics. In addition, there is a clear and solid equipment (CV input with attenuator and manual “gain” control), so that the module is very versatile. User interface Inputs (for each of the 2 sub-modules): … Read more
A Lowpass Gate (LPG) is an odd device. It uses a vactrol circuit and couples a low pass filter to an amplifier (VCA). Then why not just use a filter and an amplifier separately? The LPG can be switched between VCF, VCA and the combination VCF / VCA! In addition, the module is built with … Read more
The A-132-8 is a module designed for polyphonic operation with 4 voices with a total of 8 VCAs. Why so many VCAs, one might ask, wouldn’t 4 be enough? Two VCAs connected in series are responsible for each of the four synthesizer voices on the A-132-8: The first VCA always works linearly, the VCA afterwards … Read more
