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. Excellent audio quality (THD 0.003%) and the VCA closes completely.
Due it's unipolar design they process only positive CV signals so less suitable for ringmodulation but with a pulse 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.
