Available as an assembled Module and as a DIY project.
This Module is discontinued.
Specs are approved by the manufacturerSimple PCB layout with common, easy to source components.
The GMSN! Pure range is aimed squarely at Synth DIY. We’ve stripped it right back to the bare essentials. No bells. No whistles. Just Pure Modular Synthesis.
The GMSN! Pure VCA is an exponential voltage controlled amplified based on the THAT2180 VCA chip. It has control over the Offset and CV In level. There are inputs for the Signal In, CV In and Signal Out. It can be used to control both audio and CV signals. The THAT2180 VCA chip is used in high end audio kit giving excellent signal to noise ratio.
The circuit board is laid out cleanly to make component population and soldering a breeze and the build documentation includes step by step instructions, as well as fault finding hints and tips. There is also a full explanation of how the module works, broken down into the basic building blocks. This isn’t just a kit, it’s a comprehensive introduction to analogue VCA circuit design.
The GMSN! Pure VCA is available as a PCB, PCB and Panel, Full Kit or Pre Built and Tested Module.
