measuring

Frequency response: 3.15 Hz - 40kHz Sensitivity: 12.5mV/Pa CRY371-CRY507 1/2" IEPE Free-Field Measurement Microphone Kit This kit consists of CRY371 Measurement Microphone and CRY507 IEPE Preamplifier self-developed by CRYSOUND, with a BNC port for output. CRY371 Measurement Microphone can also be combined with CRY510 to launch a kit. Stainless steel case High stability Wide range of applications Compliance with IEC 61094-4:1995 Measurement microphones - Part 4: Specifications for working standard microphones Compliance with GB/T 20441.4-2006 Measurement microphones - Part 4: Specifications for working standard microphones CRY371 is a pre-polarization free-field measurement microphone that measures the undistorted true sound pressure of the microphone before it is placed in the sound field. The presence of the microphone in the sound field will affect the sound field and change its high-frequency sound field. Based on this characteristic, the free-field microphone has its frequency response adjusted to compensate for errors brought to high-frequency sound pressure in the sound field. This kit includes a CRY507 IEPE preamplifier which is powered by constant current source and featured by very high input impedance, very low noise floor, and a very wide frequency response range. It can be used with CRY300 series 1/2'' pre-polarization measurement microphones. The output interface uses a BNC plug, which can be easily connected to a professional measurement system. It is suitable for electroacoustic testers, multi-channel analyzers, noise analyzers and other instruments.
