The Global Leader in Long Range Acoustic Hailing Devices

LRAD 500X MMT

Powerful, Intelligible Air-to-Ground
Communication

LRAD 500X MMT Helicopter-Mounted System

The LRAD-500X MMT is an advanced air-to-ground communication system that is self-powered and completely autonomous from other aircraft systems. The LRAD 500X MMT broadcasts loud, highly intelligible voice messages and attention commanding warning tones out to 2,000 meters over wind, engine and rotor wash. Classified as a payload by the FAA, the LRAD 500X MMT easily mounts to the cabin floor of a wide range of helicopters using cargo tie-down quick disconnect fittings. Featuring a rugged mount with a full range of pan & tilt motion and an integrated rechargeable power pack that provides 4 to 6+ hours of continuous operation, the LRAD 500X MMT significantly enhances the operational effectiveness of airborne law enforcement in a variety of missions.
