Cwejman VCA-4MX


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.

We currently do not accept pre-orders for Cwejman products. If you are interested in this module, please use the availability notification. The number of Cwejman circuits is limited. Therefore, we recommend you to order online IMMEDIATELY when a module becomes available. Enquiries via e-mail or telephone are usually not fast enough. (More detailed information can be found on the product page.)



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.

All Cwejman modules are screened against interferences, protected against reverse polarity and contain calibration options on the backside. (See photograph.)

Attention: Unlike other manufacturers, the red stripe of Cwejman's flat ribbon cable indicates the positive +12 V rail, not the negative one!


We currently do not accept pre-orders for Cwejman modules. For some products, there are waiting lists with pre-orders from the years 2013 to 2017, which are being processed as a matter of priority.
If you’d like to be informed as soon as this module is back in stock, please activate the availability notification via e-mail.
Please note: The number of Cwejman modules is always limited and much lower than the number of interested parties. Therefore, we recommend to order IMMEDIATELY and ONLINE if a Cwejman product becomes available. Enquiries via e-mail or telephone are usually not fast enough.
If the demand is higher than the supply, unfulfillable pre-orders will be deleted. In this case you’ll receive an e-mail. (Pre-orders on the waiting lists mentioned above are excluded from this policy.)
