Modification of solid state RFT microphones from Gefell MV 690, MV 691, MV 692, PM 750, PM 860, UM 705 to 48V phantom power and 3-pin XLR connector
(redesign the old plug piece)
We add a small low noise SMD stabilization board to reduce the Phantom voltage of 48V to 12,5V. After modification you can use the microphones directly with a standard 3-pin XLR microphone cable on each standard microphone input with Phantom power of 15-48V.
