AHD Acoustic Hailing Device Long Range Communication Highpower loudspeaker M-415

Long Range Acoustic Hailing Device M-415

The M-415 (Long Range 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 2.000 m.
The acoustic device 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 long range mobile applications under the harshest weather conditions in military use.

Marine and MIL certification for the system is available.
