The A-132-8 is a four-channel dual VCA. It was created to influence polyphonic patches in volume and to make them playable dynamically. The first VCA per channel works in a linear fashion. The second circuit can be switched to exponential behavior. A Sum Out eliminates the need for a mixer at the end of polyphonic signal chains.
The module A-132-8 consists of four channels with two VCAs each. The amplifier circuits are labeled GL (Gain Linear) and GX (Gain Variable). There is an audio input, control voltage paths for the VCAs and an audio output per channel. Global GL and GX potentiometers allow you to open the amplifiers manually. The first VCA works in a linear fashion. It is intended to be used with an envelope. The second VCA can be switched between linear and exponential behavior. This circuit is predestined for amplitude modulation, e.g. using velocity. Besides individual outputs, there is a Sum Out connector.
WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
