The Cwejman VCA-4MX Quad VCA / Mixer is one of the purest sounding VCA's out there in the ÿeurorack world. Its true transparency is sought-after, a lot of users tend to use it as the final VCA-mixer in their system.


The Cwejman VCA-4MX Quad VCA / Mixer consists of four individual voltage controlled amplifiers.

All amplifiers are identical and work in a semi-logarithmic mode. The semi-logarithmic transfer function is much more practical than a true logarithmic because the semi-logarithmic mode "imitates" the natural behaviour of volume controllers. Amplifiers accept both DC and AC signals.

The VCA-4MX has eight outputs for maximal flexibility. All amplifiers has an individual output, two summing otputs for all amplifiers (both normal and inverted) and additionally two summing outputs for VCA1 + VCA2 and VCA3 + VCA4. The VCA-4MX can be used as quad attenuator (using all four amplifiers separately), as a four input mixer (using summing outputs) and as two separate two inputs mixers.

All amplifiers has a dedicated level controller (knobs) and CV inputs which controls outgoing signals attenuation in semi-logarithmic mode. The manual controllers (knobs) determinates the maximal amount of controlled gain.
