Condenser ultrasound microphone Polaroid/CMPA

  • Auditory

  • The Polaroid electrostatic transducer provides the best sensitivity of all available microphones in the frequency range between 20 and 60 kHz. It is comparable to the CM16 capsule but has a larger backplate and a slightly thicker metal film diaphragm. The original Polaroid transducer capsule is fully encapsulated in a protective aluminium housing and can be replaced by releasing a few screws. This microphone model requires an additional 200V polarization voltage that is supplied by the UltaSoundGate base units.
