The Sennheiser EW 512 G3 is a wireless lavalier microphone system intended for theatre and video production purposes.  The included MKE-2 EW is a discreet omni-directional electret lav mic that is easily hidden within clothing while still picking up clear and concise speech. The mic then connects to the small SK 500 G3 body-pack transmitter which can be placed on a belt line or within a pocket. Sennheiser’s scan and sync functionality means communication and signal transmission between the transmitter and the EM 500 G3 rack receiver is a quick and easy process.
