The VnIcursal VCA is the smallest, most compact Voltage Controlled Amplifier in the eurorack market. It provides 6 OTA(LM13700)-based linear VCAs in 8hp. The 6 VCAs are summed together so it can be used as a voltage controlled mixer. Each VCA is normalled to the sum so they can be removed from the mix and used on their own. When a voltage is inserted into the CV in the potentiometers act as attenuators. With a control voltage of 5 volts the VCA will be at unity gain, anything above that can clip. LED brightness with or without CV in provides constant feedback of each channels amount of gain.
