Product Overview

The RP21C is a lightweight, portable LRAD (Long Range Acoustic Device) designed for high-intensity acoustic hailing, voice warning, and public address applications. Leveraging directional acoustic technology, it delivers high speech intelligibility over long distances, making it ideal for airport bird control, law enforcement, and mass notification. Equipped with USB, AUX, and MIC interfaces, this acoustic hailing device ensures stable, reliable performance for professional use.

Description of Characteristics

• Outstanding High-intensity Sound Performance

The device delivers a peak sound pressure level of 153 dBA@1m and a maximum range of 1,259 m, enabling effective long-range sound coverage and powerful sound dispersion.

• Excellent Acoustic Directivity

At a frequency of 2 kHz, the beam angle is only ±15° (-3 dB attenuation), minimizing indiscriminate sound wave diffusion and enabling more precise directional interference/notation.

• Outstanding Broadcasting and Voice Projection Performance

The device supports a frequency response ranging from 250Hz to 7000Hz, covering human voices, alarm sounds, and common audio frequency bands with exceptional sound reproduction quality.

• Portable Design

A perfect balance between performance and size/weight, with dimensions of 485mm × 207mm × 249mm and a weight of 11kg, making it ideal for mobile deployment scenarios such as single-person or vehicle use.

• Comprehensive Functionality and User-friendly Operation

The back features ergonomic control buttons, knobs, and interfaces such as USB and AUX, offering extensive and versatile functionality. All operations can be performed effortlessly via these controls, even when wearing gloves or in extreme weather conditions.

• Military-grade Environmental Adaptability and Reliability

The product has passed rigorous tests under the U.S. military's MIL-STD-810H standard, including high/low temperatures, humid heat, sand/dust exposure, rain immersion, and drop tests, while featuring IP65 protection for stable operation in extreme climates and harsh environments.
