The LRAS1515AI Active Long Range Acoustic Hailing Speaker System is portable and delivers high sound pressure, highly directional, high-definition audio. Within the system, the LRAS1515PII Acoustic Hailing Player is equipped with a built-in full-digital AI anti-feedback module that effectively eliminates microphone feedback, ensuring clear and stable sound output.
The system is suitable for a wide range of applications, including military operations (anti-terrorism, explosion-proof tasks, border and coastal defense, marine surveillance, sentry posts), public security (crowd control, safety and stability maintenance), public safety (joint defense, fire protection, safety supervision, bird dispersal at airports), emergency response (rescue operations, meteorological and geological early warning), and public address (squares, wharfs, factories, and large-scale projects).
The system consists of the LRAS1515PII Acoustic Hailing Player, LRAS1515S Active Directional Long Range Acoustic Hailing Speaker, and LRAS1515M Handheld Microphone.
