  • For airbag measurements

FEATURES

  • The preamplifier, cable and its connectors all fulfil electromagnetic compatibility (EMC) requirements
  • LEMO connector for instrument input socket
  • Patented charge injection calibration (CIC) technique for on-site calibration of the whole measuring channel including the microphone
  • Wide dynamic range
  • Very low inherent noise, high input impedance
  • Low output impedance and high output current allow use with long extension cables
  • Wide working temperature range
  • Excellent phase linearity

The low output impedance and high output current capability mean that you can use long cables between the preamplifier and your measuring instrument without loss of signal quality. 

The high distortion limit together with an extremely low inherent noise level gives a wide dynamic range. You can connect ¼" microphones directly and 1/8''-types using an adaptor.
