DAQ: Data Acquisition Card

The SMRU Consulting Data Acquisition card provides reliable, low power, and cost-effective digitization of audio data. We use this same DAQ card in our Acoustic Processing System (APS) which is integrated into our other Passive Acoustic Monitoring (PAM) systems. Our DAQ card is available as a stand-alone device suitable for integration into other PAM systems or for development purposes.

Compact and easy to integrate into other systems, a single card is capable of sampling up to four analogue   channels simultaneously at up to 1MHz per channel at 16 bit depth, outputting the data over a USB 2.0 connection.

Multiple cards may be stacked (connected vertically) to provide up to 16 channels ALL sampling simultaneously and synchronized through a card synchronization connector.

Input/output

  • One input using pluggable screw terminal connectors providing 12vDC power in

  • Four inputs Chan 0, 1, 2, 3A and Channel 3B using pluggable screw terminal connectors each providing:

  • +12v DC Out, Signal + in, Signal – in, 0v/Ground.

  • The last Input Channel 3B is available with some user configurability.

  • Audio outputs for all input channels are brought to a multipin connector.  

  • One Mini USB 2.0 Data connector, for connection to a PC or other OEM equipment.

Applications

Analogue Audio Data collection using:

  • HYDROPHONES, MICROPHONES, GEOPHONES etc. with or without pre-amplifiers.

  • High Volume Data Analysis.

  • Marine environmental noise measurement/recording and analysis including Marine Mammal vocalizations.

  • Terrestrial noise and sounds e.g. bats, structural stress and civil construction work.

  • Ideal for single or multi-channel applications in research, industry, & security work.

Use Cases
