CRY3403-S02 Free-Field Microphone Set, 1/4", 4mV/Pa

CRY3403-S02 Free-Field Microphone Set, 1/4", 4mV/Pa

CRY3403-S02 is a 1/4-inch free-field prepolarized measurement microphone and preamplifier set designed for ultra-high-frequency and high dynamic range acoustic measurements.

The CRY3403-S02 is engineered with a unique design that ensures an exceptionally wide and flat frequency response, extending up to 90kHz, and can handle sound pressure levels up to 154dB. This microphone set is an excellent choice for general-purpose measurements, offering superior performance for high-definition audio analysis and a range of ultrasonic acoustic applications.

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