CRY6151B Electroacoustic analysis system

CRY6151B is a full-featured electroacoustic device tester newly launched by CRY Sound. It is powerful and stable. It can measure the performance indicators of headphones (USB, Bluetooth, anti-noise), microphones (electret, MEMS, moving-coil type), headphone and microphone assemblies, receivers/headphone speakers, speakers/loudspeakers (common, Bluetooth), loudspeaker crossover devices, and other electroacoustic devices, such as sensitivity (SPL), impedance, distortion (THD), resonance frequency F0, left and right headphone balance, left and right headphone position, phase polarity, microphone current and voltage, SNR, microphone directivity, speaker's TS parameters, telephone receiving and sending loudness ratings, etc. Its test frequency range can be up to 20 Hz - 20 kHz.
