Takaab 2VCA - Dual Voltage Controlled Amplifier

The Takaab 2VCA is an affordable dual linear voltage controlled amplifier in 3HP, based on the LM31700 chip. In contrast to our VCA-2180 the 2VCA has a near linear response, is pre-offset to be normally closed, and best of all there are two of them!

A positive voltage applied to the CV input will amplify any signal put through the 2VCA at more-or-less unity gain. So a +/-5V audio signal will be amplified to 5V if there is a +5V applied to the CV input. The 2VCA is DC coupled so it can be used to amplify voltages as well as audio signals.
