CRY3401-S01 Free-Field Microphone Set, 1/4", 15.8mV/Pa

CRY3401-S01 Free-Field Microphone Set, 1/4", 15.8mV/Pa

CRY3401-S01 is a 1/4-inch free-field prepolarized measurement microphone and preamplifier set designed specifically for sensitive acoustic testing in low-noise environments.

The unique design of CRY3401-S01 provides it with very low self-noise and a measurement frequency range of up to 40 kHz. It is capable of withstanding sound pressure levels up to 142 dB. It is an excellent general-purpose measurement microphone set suitable for high-definition audio measurements and other ultrasonic acoustic applications.

  • High-frequency free-field microphone set
  • TEDS microphone set
  • Extensive compatibility
  • Durable, reliable, and high-quality
