CRY6151B Electroacoustic Analyzer

CRY6151B is a robust and reliable electroacoustic analyzer with a frequency range spanning from 20Hz to 20kHz. It is designed to evaluate a diverse array of devices, including USB, Bluetooth®, and noise-canceling headphones; electret, MEMS, and moving-coil microphones; receivers; speakers; Bluetooth loudspeakers; and loudspeaker crossover devices.

Technicians can assess device performance using key metrics and procedures such as sensitivity (SPL), impedance, total harmonic distortion (THD), resonance frequency (F0), headphone balance, headphone positioning, phase, polarity, microphone current and voltage, signal-to-noise ratio (SNR), microphone directivity, speaker Thiele/Small (TS) parameters, and telephone loudness ratings. The CRY6151B offers comprehensive capabilities for thorough and precise evaluation of electroacoustic equipment.
