See exactly what your signals are doing! VM is a super-skinny (2HP) volt meter utility module for your Eurorack modular synthesizer. It offers a bar-graph display that gives you a quick, easy to read indication of what your signal’s voltage is and where it’s going, even from across the room. It can indicate voltages between -12.9V and +12.9V, with one LED per volt (and per 0.1 volt). The meter lights red to indicate a positive voltage and blue to indicate negative.
