CRY886-S01 High-Frequency Coupler Kit Components & Description：  CRY886 0.4cc High-Frequency Coupler  CRY342 1/4” Pre-polarized Pressure Field  Measurement Microphone  CRY547 1/4” ICP Preamplifier  BL5706SMB to BNC Cable / 1.5m Introduction CRY886-S01 is a high-frequency Coupler kit which consisting of the above accessories for test hearing aids at frequencies up to 16kHz. The coupler increases the resonance frequency to 30kHz, so that it will not interfere with measurements in the audible frequency range. The coupler volume is 0.4cc, CRY886-S01 has a sensitivity of 1.5mV/Pa and the noise floor 40dB(A). CRY342 measurement microphone is a pre-polarized 1/4 inch pressure 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 168dB. The Titanium membrane 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. And finally, CRY886-S01 Coupler kit is designed for accurate and repeatable use, and also suitable for research, measurement and production test applications.  Meet IEC TS 62886:2016 Electroacoustic – Hearing aids – Method for measuring electroacoustic performance up to 16kHz  Meet IEC 61094-4:1995 Measurement microphones―Part 4: Specifications for working  standard microphones Add: No.31-1, Xianxing Road, Xianlin Industrial Park, Yuhang District, Hangzhou, Zhejiang
