It is the latest full-function powerful electro acoustic tester with strong stability and it can test the following device:

headphone (USB, Bluetooth,anti-noise),microphone (electret, MEMS), headphone and microphone, telephone receiver, headphone speaker ,Loudspeaker, loudspeaker box(common, Bluetooth),loudspeaker box frequency divider, and other acoustical device.

Test the following index:

Sensitivity (SPL), impedance, THD, F0 (resonant frequency), balance degree of left and right headphone, position of left and right headphone, polarity, microphone current and voltage, signal to noise ratio, microphone directivity, loudspeaker T&S parameter. 

 

Compared with similar products in domestic and overseas, CRY6151 has clear advantages:

1. CRY6151 is the first instrument to test bluetooth audio in China, and it can perform automatic pairing instead of manual clicking;

2. Four-channel data acquisition system is adopted, and two components of headphones and two microphones can be tested synchronously; 

3.The instrument has high precision and high speed. Frequency sweeping method and psudo white noise test can be selected. One-time-sweep can finish testing and determining parameters, like frequency response,sensitivity (SPL), THD, impedance, F0, phase, balance degree, polarity, etc;

4.Each testing program can add and determine any parameters with strong saving function.It can adapt to application in labtory and production line in all directions.

 

Based on Windows XP, in bilingual Chinese-English, it is easy to operate and it conforms to the usual practice of Chinese.

It has four-channel synchronous acquisition. Components of headphones and microphones can be tested synchronously.

One-time-sweep can test sensitivity, THD, impedance, phase, balance degree and determine all the testable indexes.

 

 

 It can test Bluetooth headphone and Bluetooth loudspeaker with automatic pairing instead of manual clicking 

 

Its precision and speed is much better than of similar instrument in domestic: sensitivity testing precision is less than ±0.2dB and highest testing speed reaches 0.5s.

 

 Various testing methods and sweep range can be selected optionally

Flexibly configure input end and output end

Optional sinusoidal wave effective value and FFT 

 

 

Output qualified code in sub-file and flexibily work with automated test equipment
Support TTL electrical level and PLC connection

There are various miscellaneous functions, such as show or hide testing curve, mean curve, right-and-left difference of balance degree curve

Flexibly add observation program, and optionally add and delete sweep point, impedance, current, T&S parameter, etc



  

There is comparison function of d-value of each of frequency point of sensitivity, testable signal to noise ratio and d-value of microphone directivity coming with the software

Various frame-setting comprehensively can meet customer demand of production line

 

Provides various data formats, such as Word, Access database, TXT, Excel, jpg, etc;

Provides software customization, such as directivity of microphone heart-shaped graph testing, talkback access control system testing, etc
