Product information "Doepfer A-135-2 Mini Quad VCA / Mixer"
The popular Doepfer A-135 has been reduced to 8HP, making it one of the most compact voltage-controlled four-channel audio mixers on the market. The new version now offers separate All and Selected outputs for even more flexibility! The volume of each channel can be modulated via control voltage. In addition, each channel has an attenuator and a gain control on both the audio and CV inputs. The module can be used as a mixer, as a dual stereo VCA, as a quadruple VCA or as a quadrophonic distributor. Thanks to DC coupling, it can also be used for processing control voltages.
Module A-135-2 consists of four linear VCAs with mixing function.
The input level is adjusted with the attenuator. The volume control of each input signal can be controlled manually with the gain potentiometer and via a control voltage at the CV input, and can be tapped at the individual output, just like with a normal VCA.
In addition, the A-135-2 mixes the four signals at one of the sum outputs with a maximum gain of 0.6 to avoid clipping.
At the Selected output the sum signal of all VCAs appears, if no patch cable is plugged into the Out jack of the respective VCA. VCAs with a patch cable plugged into the Out jack are removed from the sum.
The All output always mixes all four channels.
Thanks to internal jumpers, the four signal inputs can be normalized with each other. Thus a signal can be distributed to 4 different channels by voltage control (e.g. for quadrophonic distribution of audio signals).

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.
