The Lectrosonics MCATA5MUWP Microphone Cable Adapter with TA5 female to micro phone jack connector helps to adapt both 2 and 3 wire lavaliere mics and line level inputs that are properly wired for a Lectrosonics 5 pin transmitter to a Lectrosonics MM400/b/c transmitter or a WM transmitter. The MM and WM transmitters will be water protected from water while this adapter is used though the 5 pin connector itself will not.
