500RXL – High-Power Directional Acoustic System.
Long Range Acoustic Device 500RXL by Revoluce is a compact yet powerful directional acoustic system engineered for demanding defence, maritime, industrial and border security environments. Optimized for clear voice transmission, high-intensity warning tones, and focused long-range output, the 500RXL maintains exceptional intelligibility even in high-noise, offshore, and extreme climate conditions.
With an effective audible range of up to 3.5 km and a broad 200–9,000 Hz frequency spectrum—including the critical 1,000–4,000 Hz band most responsive to human and avian hearing— the Revoluce 500RXL delivers unmatched communication precision and deterrence capability.
Its ±15° directional beam angle ensures highly targeted acoustic projection with minimal noise spill, while continuous 360° servo-driven rotation and sweep speeds of up to 50° per second enable rapid target tracking for crowd control, coastal surveillance, border patrol, and wildlife management applications.
Built using advanced straight-sound projection technology, the 500RXL achieves peak sound pressure levels of up to 158.3 dB at 1 kHz, independently certified by the Korea Marine Equipment Research Institute (KOMERI). This level of performance ensures dominance in long-range communication and non-lethal deterrence scenarios.
Designed for operational endurance, the system integrates LiFePO₄ (lithium iron phosphate) battery systems with optional auxiliary alternator support, enabling extended autonomous missions while minimizing maintenance.
Engineered for harsh climates, the 500RXL features an IP67-rated weatherproof enclosure, ensuring reliable operation across Indian, UAE, GCC, coastal, desert, and high-humidity environments.
With increasing demand for maritime security, disaster-warning systems, coastal defence, industrial safety, and critical-infrastructure protection, the Revoluce 500RXL stands out as a professional-grade, mission-ready, long-range acoustic solution for government, defence, and industrial operators.
