  • Sensitivity 50mV/Pa
  • IEPE constant current supply 2-20 mA | Bias: 12.5 Volt 
  • Polar Pattern: Omnidirectional
  • Frequency Response: 1.5 Hz – 20 kHz
  • Acoustic noise floor 16 dB A-weighted
  • Measuring range 16 dB(A) to SPL Peak (3% Dist.) 135 dB

Scope of delivery:

  • MP40 ½” microphone capsule pre-polarized
  • PA-1 ½” IEPE mic preamp
  • WS-RG-80 windscreen
