The VCA-4MX is a combo-module which besides being four independent premium VCAs also gives diverse mixing functions. Therefore you can also use the module as one 4-into-1-mixer or two 2-into-1-mixers. And of course you can also abuse it as four attenuators.
Four identical VCAs with a frequency range of 0Hz-50kHz. The in- and outputs properly accept loud signals with a voltage amplitude of +/-10V without distorting.
All VCAs have separate outputs but there are also positive and inverted summing outputs that turn the VCA-4MX into a four channel mixer. Likewise there are outputs that carry the mixture of channels 1+2 or 3+4. The level of each channel can be altered manually and/or with a control voltage; the CV inputs have a semi-logarithmic characteristic.
Generally all Cwejman modules are shielded from interferences and contain lots of calibration possibilities on the backside.HP : 10
