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. The potentiometers control the amount of gain, and 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 the input. LED brightness with or without CV in provides constant feedback of each channels amount of gain.
The VnIcursal is not a perfect scientifically spec’d VCA. Analog VCAs can only close so much, or be so silent. In certain situations based on power supplies and gain stages the VCA can experience some bleed or noise mainly at the sum out as all channels are passively summed then buffered.
