A-142-2 Dual Envelope Controlled VCA

The A-142-2 consists of two VCAs, which are controlled by envelopes.
Each of the two units is a combination of a simple AD / ADSR / AR envelope generator. The type of envelope can be selected using a toggle switch.
With the help of internal jumpers, it is possible to determine, for each unit, which parameter(s) should be controlled via the CVT input (e. g. only A or only D / R or A and D / R) and in which direction.
