CATCH series Voltage Controlled Amplifier
The VCA-AB is a Unipolar Linear Dual VCA. The unit contains two independent voltage controlled amplifiers (A en B) with linear response.
Due it's unipolar design they process only positive CV signals so less suitable for ringmodulation but with a puls signal to the CV input it's possible to create nice ringmodulation sounds ( the output signal level then needs to be amplified a bit).
The input signal is slightly amplified if the CV knobs are set more then 3/4. So you can level out some weak input signals.
