Hangzhou Crysound Electronics Co., Ltd. CRY341 Measurement microphone sets CRY341-CRY547

Frequency response: 4 Hz - 40kHz; sensitivity: 4 mV/Pa CRY341-CRY547 1/4" IEPE Free-Field Measurement Microphone Kit This kit consists of CRY341 Measurement Microphone and CRY547 IEPE Preamplifier self-developed by CRYSOUND, with a SMB port for output. Features Standard-compliant 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 Typical frequency response curve of CRY341 CRY341 Microphone is a 1/4'' pre-polarization free-field measurement microphone that measures the actual sound pressure on the surface of the microphone diaphragm (including changes in the sound field due to the presence of the microphone itself). 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. Preamplifier This kit includes a CRY547 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 1/4'' 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. It is also compatible with other brands of measurement microphones. Stainless steel grants it excellent corrosion resistance and protection, so it is very suitable for various harsh test environments.
