MAX-4 Acoustic Hailing Device - Maximum Acoustic eXchange ™
High Power Acoustic Communication System for mobile applications
When you need to be heard!
The MAX-4 High Powered Acoustic Communication System is an extremely effective acoustic transceiver for use in mobile hailing and listening applications. Employing a version of Conquest’s patent-pending Distant Energy Frequency Tailoring (DEFT™) Technology, the MAX-4 optimizes the acoustic signal, providing the most clarity possible and ensuring intelligibility at long ranges where others fall short. In addition, the listen-back feature uses low-noise technology to hear voice sounds originating from the target location.
Unparalleled Voice Intelligibility.
"MAX 4 showed superior voice warning message intelligibility as compared to other AHDs of similar size and power requirements."
"Only AHDs with far greater size, weight, and power requirements outperformed MAX 4"
Penn State Acoustic Performance Evaluation, November 29, 2006*
The MAX 4 is a stand-alone acoustic emitter system ready to operate immediately. Optional mounting systems can be quickly attached to many existing mobile platforms, crew served weapons mounts, tripods, or rooftops. The MAX-4 is also available as a remotely operated device allowing it to be mounted to any one of many remote mounts and pan-tilt mechanisms.
A 12 volt, 12 amp DC accessory power output is standard equipment and can operate searchlights, cameras, radio or other auxiliary devices.
