By Dialogo July 19, 2011
The Colombian Army has acquired the LRAD 1000Xi Long-Range Acoustic Device Highly Intelligible Long-Distance Communication system from AROLEN Corporation.
According to its representative in Colombia, speaking to Infodefensa.com, these systems were purchased following a demonstration of their use in June, in the southern part of the country, which led to the demobilization of FARC-EP insurgents (psychological operations).
The success of the demonstration caused the Defense Ministry to begin taking steps to acquire six LRAD 1000Xi systems for deployment by the Army on Sikorsky UH-60L and AH-60L Black Hawk helicopters and one LRAD 500Xi system for the Air Force, which is also testing the 1000 model for possible future acquisition.
The LRAD 1000Xi can be operated manually to provide clear and intelligible communication at distances of up to 3,000 meters.
Among its characteristics, it has a maximum continuous acoustic output of 153 dB SPL at one meter, weighted; a beam width of +/- 15° at one kHz; and a communications transmission range of 3,000 meters.
As far as its mechanical aspects are concerned, it measures 36 inches wide by 40 inches high by 13 inches deep; weighs 81 pounds without accessories; and is made of a molded composite, 6061 aluminum, and 316 stainless steel.
