Happy Nerding Isolator
Clean galvanic isolation from modular to balanced outputs
4 HP Eurorack module
The Happy Nerding Isolator is a 4HP Eurorack module that provides galvanic isolation between Eurorack-level inputs and balanced 1/4-inch TRS outputs, eliminating ground loop hum when interfacing a modular system with external audio equipment. It features per-channel ground lift switches for flexible grounding options and a single level knob controlling both output channels, making it an essential utility for clean studio and live performance connections.
