CRY6151B is our company newly launched a fully functional electroacoustic device tester, powerful, strong stability, can measure the headset, USB, bluetooth, anti noise), microphone (electret, MEMS, moving coil), the microphone assembly, receiver/headset speakers, speaker/speakers (normal, bluetooth), speakers frequency division device and other performance of the electroacoustic device. For example: sensitivity (SPL), impedance, distortion (THD), resonance frequency F0, balance of left and right earphones, position of left and right earphones, phase polarity, microphone current and voltage, signal-to-noise ratio, microphone directivity, speaker T&S parameters, telephone reception and transmission loudness, etc., the test frequency range can be up to 20Hz - 20kHz.

CRY6151B has high-performance hardware that can be extended to sync 8-channel acquisition / 4-channel output.2. The hardware includes sound card module, power amplifier module, signal processing module and USB communication module.3. Compact case design, simple USB data communication mode, to meet various test environment requirements of customers;Software:1. CRY6151 v8.x is based on Windows7& 32bit system and supports WinXP and Windows7&64bit systems (update drivers are required and customers are required to inform the specific operating environment), with friendly interface and powerful operation functions;2. Support a variety of sweep methods, including effective value, fast step sweep, high precision step sweep, multi-tone test, white noise, pink noise, etc. Choose different methods according to different test occasions and test requirements.3. The measurement and determination of frequency response, sensitivity (SPL), distortion degree, impedance, F0, phase, balance degree, polarity and other parameters can be completed with one sweep, making the test more accurate and faster;4. It is the earliest instrument in China that can test bluetooth audio, which can be paired automatically without manual click;Powerful sequence editing function, with virtual signal generator, multimeter, and has a perfect preservation function, fully adapt to the customer in the laboratory and production line applications.
