CRY343-C1 Microphone Set Composition & Description:   CRY343 Free field measurement microphone CRY547 Preamplifier CRY343 measurement microphone is a pre-polarized 1/4 inch free field condenser microphone. It mainly used for high-level and high-frequency measurements since the sensitivity is low. It can measure high sound pressure levels to 164dB. The titanium diaphragm can achieve high stability and accuracy in harsh environment. CRY547 preamplifier can combine with 1/4 inch measurement microphone to transform the impedance and amplifier the acoustic signal. This preamplifier has the characteristic of high input impedance, low output impedance, lower noise, wide frequency response range, etc. It can be used for the condition of electroacoustic test system or multi-noise analysis.
