CRY6151 Electroacoustic Analyzer Introduction CRY6151 electroacoustic analyzer is a PC and Soundcard based audio measurement system. With well-designed hardware and software, CRY6151 suits to test vary electroacoustic transducers. CRY6151 is the next generation electroacoustic analyzer of CRY6136, CRY6135 and CRY6125. With parallel four-channel input and output, CRY6151 can test all items (sensitivity, THD, impedance etc.) simultaneously in 1 second. Base on Windows XP, the software interface is user friendly and easy to use. The following parameters can be tested: Sensitivity(SPL), Impedance, THD, Polarity, Phase, Resonance Frequency F0, Balance of headsets, Left or Right position for headsets, Current and Voltage for microphones, Signal and Noise Ratio (SNR), Directional Response, T&S parameters for loudspeakers, Receive Loudness Rating (RLR), Send Loudness Rating (SLR). Features 1. Four-channel data acquisition, the sensitivity, distortion, impedance, polarity, F0, phase, balance and other parameters can be tested simultaneously in 1 second. 2. Data transmission interface is USB2.0, and two headphones and two microphones components can be tested simultaneously controlled by switches. 3. Available signal generator includes sweep frequency and multi-tone. 4. One of the earliest electroacoustic analyser to test Bluetooth audio product. The Bluetooth devices can be paired automatically. Application CRY6151 series electroacoustic analyzer could test the following electroacoustic transducers:  Headphone, Earphone  Microphones (Electret Mic., Dynamic Mic., MEMS Mic.)  Loudspeaker  Rec

 USB headphone, microphone or combination  Bluetooth speaker, headphone, microphone or combination Technical Specification Signal Generator  Frequency band range: 0.02 ~ 20kHz frequency band can be personalized Frequency Response: ≤ ±0.2dB (relative to 1kHz） Maximum Output Power: Left Channel 20W, Right Channel 1W Frequency Response Error: ≤ ±0.5dB（relative to 1kHz） Level Meter Range: Electrical signal: -100 ~ 10dBV Acoustic Signal: 20 ~ 140dB (0dB=20µPa) Measurement Error: ≤ ±0.5dB Noise: -100dBV
