the vca-4mx consists of four individual voltage controlled amplifiers. all amplifiers are identical and work in a semi-logarithmic mode. amplifiers accept both dc and ac signals. the vca-4mx has eight outputs for maximal flexibility; all amplifiers has an individual output, two summing outputs 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 (or rather attenuation). the semi-logarithmic transfer function is much more practical than a true logarithmic because it's "imitates" the natural behaviour of volume controllers
