●  Broadband and High Sensitivity

The operating frequency band spans 10 Hz to 10 kHz, featuring excellent reception sensitivity across the entire spectrum. It is capable of comprehensively capturing underwater acoustic signals ranging from low to mid-to-high frequencies, offering a wide signal pickup range and a flat frequency response.

●  Ultra-Low Equivalent Self-Noise

With an equivalent noise sound pressure spectral level as low as 29.1 dB at 1 kHz, it exhibits exceptional intrinsic noise performance and outstanding weak-signal detection capabilities, enabling the precise identification of faint underwater acoustic signals.

● Self-Contained Integrated Design

Integrating signal acquisition and data storage capabilities, this system eliminates the need for external front-end acquisition terminals; it can be deployed directly underwater to operate independently *in situ*, offering simple deployment and convenient operation.

● Reliable Metrology and Stable Operation

Calibrated by the Level I Hydroacoustic Metrology Station of the National Defense Science, Technology, and Industry Bureau, the system features traceable measurement values and precise, reliable core performance indicators. Designed for compatibility with underwater marine environments, the complete unit operates with exceptional stability, fully meeting the requirements for long-term.
