MicroStepping Voltage Controlled Amplifier

Category: VCAs, mixers and modifiers

The JEµVCA provides basic amplitude modifications based on CV input. It is not able to handle quick changes in envelope, but it is therefore available at a lower price. It has both linear and exponential (logarithmic) responses, which needs to be pre-selected before installation. There are three individual modules on each 4 HP front panel, and a small light indicates weather or not it is working in linear mode. The amplitude is adjusted in 128 steps, making the sound a little bit similar to a S&H module at work, with pronounced digital stepping.
