Condenser ultrasound microphone

Avisoft-Bioacoustics CM16/CMPA

Externally polarized condenser microphone for UltraSoundGate xx16x

part #40011

  • Frequency range : 2 kHz – 200 kHz
  • Approximate input-referred self-noise Level (bandwidth: 30-50 kHz) : 18 dB SPL
  • Approximate sensitivity : 500 mV/Pa
  • Connector: male XLR-5 plug
  • Removeable protection grid
  • Dimensions : 36 x 36 x 60 mm
  • Weight : 65 g
  • Supplied accessories : 5 m extension cable (other lengths of up to 300 m are available on request), high-quality Sennheiser microphone clamp and mini tripod
  • Optionally available USB-powered microphone heating

The condenser microphone Avisoft Bioacoustics CM16/CMPA provides a good compromise between sensitivity and flatness of the frequency response. It consists of an (replaceable) externally polarized metalized film diaphragm and a metal back plate. This microphone model requires an additional 200V polarization voltage that is supplied by the UltaSoundGate base units. An optional USB-powered heating module can prevent condensation when the microphone is being used in the field.
