The M51 PTT(Push to talk) is used to connect your headset to your radio. It allows you to communicate on your half-duplex communication lines, including two-way radio, using a momentary button on the unit to transmit. Both headset and radio should be connected in order to use the PTT.
Your M51 PTT can be seamlessly integrated into your existing Earmor M32 Hearing Protector system or even the headsets of other vendors(MSA Sordin, 3M Peltor, etc..), allowing the operator to have the ability to use their communication system in a high noise environment.
Accepts input from Nexus TP-120 U-174 Military Connector ONLY (NATO Standard)
