E3A Recording System (Autonomous Recording Unit)

The E3A system is a “plug and play” system (also referred to as an “autonomous recording unit” or ARU), that can be further configured to the needs of a variety of applications and users. 

For example, the two CZM microphones, pictured here, are configured to a 180 degree pickup pattern positioned in tandem on a mounting bar.  This configuration produces a high resolution ambient stereo recording, within a 360 degree radial.

It has thus become the microphone of choice for recording avian species, amphibians, mammals and any other sort of environmental sounds. Recordings are digital and may be:

  • Monitored during recording by the use of the headphones
  • Downloaded to a computer system for further manipulation, analysis, chart & graphic display, or other applicable use

  • Two CZM microphones (180 degree configuration), equipped with cloth covers
  • Digital recorder (Marantz PMD 670)
  • Calibrated tone generator to provide a recorded reference level
