Each S.A.F.E. 1000 system is matched and shipped from factory with a unique security code. The encryption eliminates the possibility of additional wireless receivers from intercepting the signal. Even additional S.A.F.E 1000 receivers cannot intercept the signal. This system is packaged with the SAFE 1000 receiver and SAFE-HD handheld transmitter with Electro-Voice ND/767 microphone head. The transmitter accepts lavaliers, head-worn microphones and instrument cables terminated with a TA4 connector.
