The Shure MD40LEMO Microdot adapter is designed to allow you to plug your Microdot-equipped microphone into a compatible wireless transmitter with a LEMO 3-pin input. The Microdot female end supports mics like Shure TwinPlex and models from DPA and Countryman. The locking LEMO 3-pin connector allows proper hookup to Sennheiser 2000 to 9000 Series bodypack transmitters as well as Shure AD1/ADX1 LEMO versions.
