Just getting phantom power noise when mounting Sanken CS-M1 to Ronin 4D ext XLR plate. Anyone else done this before and had it work?

Have tried different cables, different ext plates, and no luck, but it works with other 48v mics, and the Sanken works when plugged in to a mixer/recorder - just not when plugged in to the camera.

+48 switch is toggled on.
