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.

Not sure? The Constant Able PTT auto-detects impedance — no manual selection needed. Use our PTT Configurator to find the right match.

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.
