1.1 Product Overview
CRY6151 is the newest electro-acoustic analysis system developed by CRY Sound with powerful functions and strong
stability. It can measure the performance of headphone (USB, Bluetooth, ANC), microphone (electret, dynamic and MEMS),
receiver, micro speaker, speaker, communication helmet, etc. The measurement parameters include frequency response,
sensitivity, impedance, distortion, resonant frequency(F0), balance, 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, CRY6151 electro-acoustic analysis system is not only a new breakthrough in the series products of
CRY6125, CRY6135, CRY6136, but it also the earliest instrument that can test the Bluetooth Audio, as well as realize auto
pair without manually click.
The software and hardware of CRY6151 has been fully upgraded.
Hardware:
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.
Software:
V8.0 is based on Windows 7 & 32 bit system and supports Win XP and Windows 7 & 64 bit system (needs to update
the driver). It has friendly interface, convenient operation and powerful functions. Besides having all test functions of early
electroacoustic instrument, the following functions have been added:
Higher and faster test precision;
Support a variety of stimulus type, including RMS, Rapid Stepped Sweep, Precise stepped sine sweep, Multitone,
White noise and Pink noise.
Single sweep measure Frequency Response, Sensitivity (SPL), Distortion (THD), Impedance, F0, Phase, Balance,
Polarity, etc.
Interface for multiple screen can view a variety of test curves;
All test items are free to be added and deleted;
Strong saving function, to meet the application requirements of laboratory and production line simultaneously;
Devices are classified by sensitivity or frequency response frame, the bar code of device can be read;
Device type can be selected freely, input and output port of instrument can be customized;
Strong information system make it easier for users to operate the software;
Various auxiliary functions, such as showing or hiding the testing curve and so on
