This module gives you no less than three fully independant linear VCAs with very similar response between each VCA in the same module or between modules.

The 3xVCA is great for adding extra life and dynamics to CV modulations as well as for regular audio duties such as a good sounding Amplitude Modulation all the way thru the audio spectrum.

This module requires calibration in several steps, achieved precision depends on the precision of your multimeter. It can be calibrated for either 5V or 8V CV. Assembled modules are calibrated to 1.00x gain (0dB) at 5.00V CV, that means 8.00V CV will give a 1.65x gain (4.35dB).

Kits comes supplied with PCB, front panel (PCB material), component kit, power cable and mounting screws. Solder and tools are not supplied.

Another nice RYO buildReview by Sam
The RYO build guides are so clear and concise that it's hard to go wrong. As a relative beginner the BOM made it easy to source my own parts.

The panel is precisely cut and the board is high quality and easy to solder. It took about 2 hours to put together and 30 minutes or to calibrate (I used 5V from 2 power cables).

This module has already opened a world of options in my small (and rapidly growing!) set up.

I will highly recommend this module and I'll definitely be building more from RYO.

Like everything I've bought from Modular Addict the shipping to NZ is amazing and makes DIY incredibly accessible (and addictive!).
