CR series engineering level measurement and recording micro- phone adopts 48V phantom power supply, measurement micro- phone cartridge and three core XLR connector. According to the different diameters of the microphone cartridge, CR series recording microphones are divided into three types:  1 inch, 1/2 inch, and 1/4 inch. Each type of microphone has different characteristic parame- ters such as maximum sound pressure level, sensitivity, frequency response range, and equivalent noise level. With corrosion-resistant metal diaphragm, omnidirectional, and high   sensitivity, it is suit- able for on-site pickup in concert halls and acoustic instruments, achieving precise, detailed, and natural sound reproduction.
