AMAR G4
Autonomous Multichannel Acoustic Recorder Generation 4
This customizable, fully autonomous underwater sound and data recorder is a robust and effective system. With removable memory and pre-packaged battery packs, it’s quick and easy to refresh the AMAR and put it back in the water. Waveform Audio File Format (WAV) and Comma-separated values (CSV) files are saved to Secure Digital (SD) cards, directly readable by your computer.
The high-level overview for operation is to configure the AMAR, get status updates, and download test data over Wi-Fi. Multiple battery packs can be daisy chained together for year-long continuous recordings.
The innovative design provides a low noise floor of -150 dB re FS per root hertz at all sample rates. We work closely with hydrophone manufacturers to develop the right system for your needs. It includes three real-time clock options, including Chip Scale Atomic Clock (CSAC), for precise data timing.
