A little gadget for coupling a pair of BM9 ribbon mics at 90 degrees to one another.
Simply remove the top caps from the mics and screw the adapter in place.
Made from high quality Delrin engineering plastic, which isolates the microphones from one another and prevents ground loops forming.
Also fits Black Ops and the old BM3 / BM4 mic from B&O.
Price includes postage.
