A-100 analog modular Website
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 module is no longer in production. The A-111-1 was the high-end model among Doepfer’s oscillators and is only available on the used market. The successor model with some detailed improvements is the A-111-2. Compared to the A-110-1 or A-110-2, the A-111-1 offers expanded synchronization options, an additional input for linear frequency modulation, and a … Read more
An almost ideal VCO for small, portable module systems: The A-111-3 measures just 4 TE! At its core, it is the same VCO as the A-111-2 High End VCO II, which, however, is much more luxuriously equipped. So, again, we’re dealing with a highly tuning stable oscillator that offers pretty perfect tracking of 1V/octave over … Read more
The module is no longer in production. The A-121 is an early but very neat filter design by Doepfer. Unfortunately, the Curtis module CEM 3320 used is no longer available, so the module is no longer commercially available. It’s a shame because it has a very unique sound character and some interesting technical features. From … Read more
After the Curtis chip CEM3320 was no longer available, Doepfer had to stop production of the A-123 24 dB highpass filter. It’s a pity, because there were simply no other 24 dB high-pass filters on the market! In the meantime, however, a replica is available with the AS3320, so that there is now a 24 … Read more
The module is no longer in production. Of all the modules that are no longer in production for one reason or another (most often it was the unavailability of certain Curtis chips, like the CEM3320 here), the A-123 filter was probably the most difficult to replace. There were simply no other 24dB high-pass filters, neither … 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
The family of A-111 oscillators now includes an impressive 6 variants, all of which use the Curtis chip CEM3340 (or replica) with its triangular core and allow very precise tracking over 10 octaves and more. The A-111-4 is – nomen est omen – designed fourfold and also has a common “master” section, which affects all … Read more
