Developed with SRT and SWAT operators to tackle the toughest interoperability challenges. Auto-Sensing The Intelligence Core Push-to-talks aren’t just an accessory—they’re the core of comms. The Constant Able uses embedded proprietary algorithms to decide, rewire, and adjust gain within 100ms. Microphone Support Dynamic (Low Impedance / Mil-Spec) Electret (High Impedance / Civilian) 150 Ohm Variants Wiring Handling US NATO Standard Peltor Wired (EU Standard) No switches. No reprogramming. Radio Interface: Hytera 13-Pin (H4) Direct-connect 13-pin interface for Hytera PD and HP series portables. Compatible Models: PD6 Series (PD600, PD602, PD662, PD680, PD685) X1 Series (X1p, X1e) HP Series (HP5 / HP6 / HP7 including HP602, HP682, HP705, HP785) TD560 H3 vs H4: Hytera uses two different multi-pin connectors. The H4 (13-pin) fits the PD6xx/X1/HP series above. If your radio is a PD7xx, PD982, or PT580, you need the H3 (16-pin Hytera) connector instead. Proven Compatibility Field-proven with professional comms gear: Peltor Comtac II–VIII Ops-Core AMP MSA Sordin OTTO NoizeBarrier N-Ear 360 Connectors: U-174/U (NATO J11) or U-384 (Dual Comm Split Audio*) — If your headset downlead has red rings, you will require the TP-105 O-ring. Mission Specs Zero batteries required IP67 Sealed (Waterproof/Dustproof) Integrated hot mic shroud Rotating ambidextrous clip Buy American Act Compliant Compatibility Note DISCUS pairing: DISCUS requires a dynamic (low-impedance) microphone. You can run DISCUS in-line with Constant Able when the headset mic is dynamic. If your headset uses an electret or amplified boom mic, use Constant Able alone — DISCUS will not drive those mics. If the downlead on your headset has red rings, you will require the TP-105 O-ring as an addition to this PTT. Red rings typically indicate the U-384 (Dual Comm Split Audio*) configuration. Mission Add-ons PTT Retainer by Spiritus Systems — $8 Low-profile MOLLE mount secures your PTT to plate carrier, chest rig, or shoulder strap. Ambidextrous, shock-cord retention. Made in USA. Tactical Earpieces Dynamic and electret in-ear options — the Constant Able auto-detects either type. No variant selection needed. Looking for the legacy option? The U-94/A Hytera H4 provides basic push-to-talk without auto-sensing — available in dynamic or electret variants. Warranty DISCO32 limited warranty — 1 year from original purchase for defects in materials and workmanship under normal use. Support starts with a troubleshooting ticket at [email protected].
