    Where to use

    In addition to providing excellent performance for microphone measurements, the MIC42X G2 Module also offers ICP® and voltage input modes.

    • With any 200 V or self-polarized microphones with preamplifier
    • With any ICP® based sensor commonly used to measure vibration, acceleration, force and pressure
    • With any voltage source up to ±12 V in voltage input mode


    • 2 channels
    • 3 input modes of operation:
      • Microphone mode with 200 V or self-polarized microphone capsules with preamplifier
      • ICP® mode with 4 mA, 8 mA or 12 mA constant current at ±12 V or 24 V excitation
      • Voltage input mode with AC or DC coupling
    • Supports TEDS IEEE 1451.4 V0.9, V1.0 (Class 1 and 2)
    • 24-bit resolution, 204.8 kSa/s sampling rate per channel, 90 kHz bandwidth
    • <0.2° @ 10 kHz phase accuracy between channels of the same or any other Module
    • ±(12V, ±1.2V, 120 mV) input ranges
    • ±14.5V at 40 mA microphone pre-amplifier excitation voltage
    • 0 or 200 V polarization output
    • Microphone calibration output to inject test signals into microphone preamplifiers
    • Exceptionally low distortion and noise design
    • There are 3 distinctive input mode options for both ICP® and voltage input modes:
      • Differential or Balanced Float (±12 V excitation)
      • Single-Ended or Unbalanced Float (24 V excitation)
      • Single-Ended or Unbalanced Ground (24 V excitation)
