EA-SDA14 EMBEDDED ACOUSTIC RECORDER Compact – Multichannel – Broadband EA-SDA14 is a compact autonomous recorder able to acquire up to 4 wideband hydrophones simultaneously. Noise impact studies The Acoustic Recorder accepts both passive and preamplified active hydrophones. Its wide band analog input allows up to 1MHz with a dynamic range greater than 100dB guaranteeing efficient signal to noise ratio. Marine Renewable Energies The embedded digital signal processor allows high speed acquisition, filtering and storage. In autonomous mode, data is stored whether on SD Card or hard drive. In wired mode, data is stored then transferred via Ethernet. Its power consumption is between 2.5 to 3.5W in active mode and less than 1mW in sleep mode. EA-SDA14 can be programmed with a mission schedule including date of beginning, sleep and record periods in order to improve battery life. The configuration and monitoring are facilitated through web browser interface. Multichannel: up to 4 synchronized channels Broadband: 3Hz up to 1MHz acquisition Wide dynamic: 24bits recording Versatile: Wired and autonomous modes Easy to use: Intuitive Embedded Web Interface Environmental Monitoring Cetacean Research Seismic / Shipping / Construction Options Up to 4 hydrophones Passive and/or Pre-amplified Up to 2TB memory extension on hard drive Additional battery extensions for larger autonomy Temperature – Pressure Attitude sensor GPS data input Dimensions: 32cm long, 12cm in diameter Weight: 5Kg in air, 2Kg in water Depth: 100 meters /deep sea option Power: 6 or 18 D cell batteries + battery extension packs option Storage: 128GB SD Card, 512GB SSD, 1 or 2TB hard-drive RTSYS – Marine Technologies SAS with capital of EUR 500,000– RCS Lorient 524 201 134 –TVA FR32 524 201 134– Code NAF : 7112B

EA-SDA14 4 Synchronized recording channels Channels are electronically synchronized and calibrated at +/- 0.2dB. Gains are electronically configurable on each channel between -4dB and +16dB. High pass filters are also configurable. Hydrophones are easily plugged in and out from the EA-SDA14 recorder. Broadband High Data Quality Eight recording frequencies going from 39.0625kS/s to 2.5MS/s are selectable. The EA-SDA14 can thus monitor noises and a frequency bandwidth going from 3Hz to more than 1MHz guaranteeing great dynamic and Signal to Noise Ratio (>100dB). This high SNR allows recording...
