Compact Acoustic Hailing Device M-115

The M-115 (Acoustic Device) Active High Output Emitter / Directional Loudspeaker Module has been designed for maximum speech intelligibility over long distances – it is capable of generating over 80 dB at target distances greater than 500 m.
The system features internal integrated DSP controlled power amplification as well as control, level and safety functions including AP-Lock.
These high performance emitters are designed for mobile applications under the harshest weather conditions in military use. Marine and MIL certification for the system is available.
