The RMB-HMAB1 is a custom-fit protective case for the Lectrosonics HMa UHF wireless transmitter.  The case is designed to extend the life of the transmitter, protecting the unit from light impacts and scratches. 
The case is made using a thin layer of padding wrapped in abrasion-resistant 1000-denier Cordura� material.  There is a clear vinyl window over the transmitter controls and display screen.  The window allows the user to view the display and access the transmitters controls.
There is a convenient belt-clip so that the microphone and transmitter can be clipped to a belt or audio harness.  There is also a �D�-ring for use with a strap (sold separately).
The custom-fit case secures tightly around the transmitter but can be opened quickly to access the unit for battery changes.
