Key Features
-
32-bit High Precision & Flexible Dynamic Range
Equipped with a 32-bit ADC and 5-stage configurable digital gain (0 dB to 50 dB), the DH-100 delivers exceptional dynamic range to capture both faint marine biological sounds and high-amplitude industrial noise without clipping.
- Wideband High-Speed Sampling
Supports sampling rates from 128 ksps up to 512 ksps with a native acoustic bandwidth of 10 Hz – 100 kHz (expandable up to 120 kHz), covering the full spectrum of ambient noise, marine mammal vocalizations, and high-frequency sonar signals.
- Sub-Microsecond IEEE 1588 Multi-Device Sync
Built-in support for IEEE 1588 (PTP) and NTP time synchronization enables seamless multi-hydrophone array positioning (TDOA) and localized sound source tracking.
- Dual Ethernet Architecture & Edge Storage
Features independent 100Mbps Ethernet interfaces for data streaming and system management. Supports up to 2TB local MicroSD card storage for fully autonomous, long-term underwater deployment.
- Auto-Acquisition & Voltage Monitoring
Designed for autonomous systems (AUVs/ROVs/Buoys), the DH-100 automatically starts recording/streaming upon power-on and continuously monitors supply voltage for reliable field deployment.
- Ultra-Low Power Consumption
Consuming only 2.1W at 12VDC, the DH-100 maximizes battery lifetime for autonomous subsea platforms and long-term buoy deployments.
Applications
🐋 Marine Mammal Monitoring & PAM
Tracking, localization, and population assessment of cetaceans (whales, dolphins) across broad frequency bands.
🚢 Ambient & Anthropogenic Underwater Noise Profiling
Real-time monitoring of maritime shipping noise, pile driving, offshore construction, and ocean ambient soundscape.
🌊 Oceanographic Research & Environmental Assessment
Subsea soundscape analysis, hydroacoustic surveys, and baseline acoustic data collection for EIA (Environmental Impact Assessment).
🤖 AUV / ROV / Subsea Glider Integration
Compact dimensions Φ50 mm x H170mm , 80m rating, and low power make it ideal for unmanned underwater vehicles.
🎯 Hydrophone Array & Source Localization
Utilizing IEEE 1588 synchronization to construct hydrophone line arrays, planar arrays, or distributed spatial tracking networks.
