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 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 behavior of volume controllers.
