CRY6151 is the newest electro-acoustic analysis system with powerful functions and strong

stability. It can measure the performance of headphones (USB, Bluetooth, ANC), microphones (electret, dynamic, and MEMS),

receivers, micro speakers, speakers, communication helmets, etc. The measurement parameters include frequency response,

sensitivity, impedance, distortion, resonant frequency(F0), balance, the position of headphones, phase polarity, current and

voltage of microphone, signal-to-noise ratio (SNR), directivity, T&S parameters, loudness rating and so on. The frequency

range is 20Hz-20kHz.

Technically, the CRY6151 electro-acoustic analysis system is not only a new breakthrough in the series products of

CRY6125,  but it is also the earliest instrument that can test Bluetooth Audio, as well as realize auto

pair without manually clicking.

The software and hardware of CRY6151 have been fully upgraded.


Use the current most popular USB2.0 interface to transfer the data, to obtain a faster speed and more stable and

reliable data; adopt the four-channel synchronous acquisition method to collect the data, which can realize two

headphones and two microphone assemblies test.


V8.0 is based on Windows 7 & 32-bit systems and supports Win XP and Windows 7 & 64-bit systems (needs to update

the driver). It has a friendly interface, convenient operation, and powerful functions. Besides having all test functions of early

the electroacoustic instrument, the following functions have been added:

1、 Higher and faster test precision;

2、Support a variety of stimulus types, including RMS, Rapid Stepped Sweep, Precise stepped sine sweep, Multitone,

White noise and Pink noise.

3、Single sweep measures Frequency Response, Sensitivity (SPL), Distortion (THD), Impedance, F0, Phase, Balance,

Polarity, etc.

4、 Interface for multiple screens can view a variety of test curves;

5、 All test items are free to be added and deleted;

6、 Strong saving function, to meet the application requirements of laboratory and production line simultaneously;

7、 Devices are classified by sensitivity or frequency response frame, the bar code of the device can be read;

8、 Device type can be selected freely, input and output port of the instrument can be customized;

9、 A strong information system makes it easier for users to operate the software;

10、 Various auxiliary functions, such as showing or hiding the testing curve and so on


1、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.

2、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.

3、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.

4、It is the earliest domestic instrument that can test Bluetooth audio. It is automatically paired without manual click.

5、It has the powerful sequence editing function, virtual signal generator, multimeter, and complete storage function, so that it is fully suitable for customers’ applications in laboratories and production lines.

6、Device grading by sensitivity or by frequency response box; device barcodes can be read in
