A-135-5 Polyphonic Mixer

The long-awaited polyphonic mixer A-135-5 is now finally available since the end of 2023. Yes, of course you could already make do with A-130-8 VCAs, for example. Some poly fans also installed a series of A-138n narrow mixers or A-138f dual crossfaders, but of course it wasn’t all that elegant. The A-135-5 mixer is elegant. … Read more

A-183-5 Quad Attenuator

Four manual attenuators in a slim 4TE module. Ok, this is definitely not an exciting module with lots of bling and two dozen hidden features. This is a tool. Simple, clear, and once you have it – indispensable. For example, I have two A-183-1 Dual Attenuator Modules (now running out of stock modules) in my … Read more

A-131 Exponential Voltage Controlled Amplifier

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

A-111-5 Mini Synthesizer Voice

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

A-130 Linear Voltage Controlled Amplifier

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

A-138f Dual 3-Way Crossfader

The A-138f is a small, dual, three-way crossfader. “Three-way” here means that we have three possible input signals and one output signal. You will look in vain for the extremely sophisticated options of the A-138e, which unfortunately is no longer manufactured. The A-138f simply fades between two signals “A” and “B” and then (from the … Read more

A-142-2 Dual Envelope Controlled VCA

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

A-150-8 Octal Manual/Voltage Controlled Programmable Switches

The A-150-8 is a very extensively equipped module that provides a total of 8 programmable 1:2 or 2:1 switches. What is programmable? Two LEDs per switch indicate which of the two “I/O” sockets on the left is connected to the “O/I” socket on the right. So we can either switch between two input signals at … Read more

A-132-3 Dual linear/exponential Voltage Controlled Amplifier

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
