The MA-Micro is a 360° Mass Notification System with an acoustic output of 118 dB. The lightweight, high power speaker broadcasts live and pre-recorded voice commands and tones over a square mile area; making the MA-Micro the life safety speaker of choice.

Leading the industry in voice intelligibility, the MA-Micro speaker design achieves an exceptional STI 0.84/1.0, ensuring commands are  clearly transmitted and heard, even in high noise environments.  

The MA-Micro comes with an all-composite, waterproof UV-resistant enclosure. Its the little brother to the battle tested MA-1, which has become the trusted mass notification system for the US military’s forward operating bases domestic and in theater.
