DSPPA LRAS1515AI - active directional long-range sound system

DSPPA LRAS1515AI is a professional active directional long-range sound system designed for applications requiring high sound pressure levels, precise directionality, and clear message transmission over long distances. The system is a complete solution, integrating the LRAS1515PII message player, the LRAS1515S directional active speaker, and the LRAS1515M handheld microphone.

The device achieves a maximum SPL level of 136±2dB (1m), providing an effective message emission range of up to 250m and sound transmission even up to 700m (80dB in controlled conditions). Thanks to the built-in AI feedback reduction module, the system effectively eliminates unwanted microphone feedback, ensuring stable and clear sound quality even in demanding working conditions. The enclosure with an IP65 rating allows for use in outdoor environments.

DSPPA LRAS1515AI is used in public safety systems, military operations, crisis management, infrastructure protection, and in sound installations in large open spaces such as squares, ports, industrial facilities, or airports.
