Review on 🔀 Nobsound MC103 Pro 3-in: 3-Way XLR Audio Switch & Converter - Ultimate Passive Stereo Selector Switcher by Patrick Reid

This little box performs exactly as you'd hope it would. Sound (and phantom power) passes through very cleanly, with no distortion, coloration or signal loss. My studio is near some radio towers (I can clearly hear NPR through some of my guitar pedals), but this unit seems immune to RF interference at all, which was a huge relief. I tested it between a Neumann KM 184 stereo pair and an Apollo Twin interface and it sounded the same as plugging the mics directly into the Apollo Twin. Another source I tried (analog synths and a drum machine through a Mackie mixer into a breakout box and then into an Apollo Twin) also sounded perfect. Duct tape and a marker to make the design even more minimal.
