Headset Compatibility
Compatible with tactical headsets using the standard U-174/U downlead.
Impedance Matching
Dynamic Mics (Low Impedance): Standard for military headsets — Ops-Core AMP, 3M Peltor COMTAC, MSA Sordin. These require amplification in the PTT circuit.
Electret Mics (High Impedance): Standard for civilian headsets, Earmor, Howard Leight, and most earpieces. No amplification required.
All PTTs below require a standard U-174/U (TP-101) downlead. If you have a U-384/U (TP-105) plug, you need our Adapter Pack.
