CRY6151 Electroacoustic analysis system
CRY6151 Electroacoustic Analysis System is a full-featured electroacoustic device tester launched by CRY Sound. It has a history of 10 years. It is powerful and stable. It can measure the performance indicators of headphones (USB, Bluetooth, common), microphones (electret, MEMS, moving-coil type), headphone and microphone assemblies, receivers/headphone speakers, speakers/loudspeakers (common, Bluetooth), communication helmets, 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.

Hardware
CRY6151 adopts a 4-channel data acquisition system, which can achieve the testing of 2 headphones and 2 microphone components in the same instrument.
Its hardware includes sound card module, power amplifier module, signal processing module, USB communication module. It is combined with software to perform various electroacoustic device tests.
Its chassis design and simple USB2.0 interface for data transfer can meet customers' various test environment requirements.
Software
CRY6151 V8.X supports WinXP and Windows 7 (32-bit) systems (corresponding drivers to be installed. It is necessary to inform the specific operating environment). It has a user-friendly interface, easy operation and powerful functions.
It supports a variety of sweep methods, including effective value, fast-stepping sweep, high precision stepping sweep, multi-tone test, white noise, and pink noise, etc. Choose different methods according to different test occasions and test needs.
The frequency response, sensitivity (SPL), distortion (THD), impedance, resonance frequency F0, phase, balance, polarity and other parameters can be measured and determined in one sweep, with higher test accuracy and faster speed.
