DISCO32 Constant Able PTT Adapter

Developed in collaboration with tactical law enforcement teams—including SRT and SWAT operators—and shaped by the insight and lessons learned as communicators in combat, Constant Able was purpose-built to tackle the toughest interoperability and interference challenges in the field.

Push-to-talks aren’t an accessory—they’re the core of what we do. Constant Able delivers unmatched compatibility, rugged simplicity, and bulletproof performance in the field. From headset to radio, it just works.

Constant Able automatically detects PELTOR or NATO-style wiring and supports both high and low impedance microphones, including electret and dynamic (150 ohm) variants — no switches, no setup, no reprogramming. It has been field-proven with a wide range of professional communications gear including PELTOR COMTAC II–VIII, XPI, Ops-Core AMP, TCI/Safariland, MSA Sordin, aviation-style headsets, as well as discreet earpieces like the N•Ear 360 Flexo and Invisio M3.

Broad compatibility with tactical headsets, earpieces, and accessories using any combination of plug type, wiring convention, and microphone impedance described above.

HOW DOES IT WORK?

Attach the Constant Able PTT to your compatible radio. Plug your headset or earpiece into the headset port using a supported connector (U-174/U or U-384 via adapter). The push-to-talk uses embedded proprietary algorithms to quickly decide, rewire, and adjust gain for different wiring and microphone types within 100ms. When you press the button on the Constant Able—protected inside an integrated hot mic shroud—your radio transmits. You speak and listen through your headset with clean, reliable audio.

Whether you’re switching gear mid-mission or managing a mixed headset inventory, Constant Able auto-configures in real time—automatically and instantly.

RADIO INTERFACE:

Engineered for plug-and-play integration with a massive range of commercial and amateur handheld radios, the Constant Able is a standout option for entry-level users, ham operators, and professionals alike.

Support for VCC (accessory power) and non-VCC configurations, Constant Able works reliably with radios like the Baofeng UV5R and others whether or not accessory power is present—a novel feature designed specifically for the unique challenges of the radio community.
