Leading the industry in voice intelligibility, the MA-1 speaker design achieves an exceptional STI rating of 0.91 out of 1.0, ensuring commands are clearly transmitted and heard, even in high noise environments.
Housed in an all-composite, waterproof UV-resistant enclosure, the battle-tested MA-1 has become the trusted mass notification system for the US military’s forward operating bases in Afghanistan and Iraq. Ideal for rapid deployment, the MA-1 system can go from its road case to fully operational in under five minutes.
The MA-1 is the “clear” choice for alerting and facilitating a response before, during, and after an event!
