补充说明：
multiple polar pattern(Uni/figure8/Omni) ·gold-plate diaphragm capsule---to assure low self-noise, high output and the accurate reproduction of even the subtlest sounds, especially high frequency signals not easily reproduced by conventional large diaphragm condenser transducers ·switchable 10dB built-in(nominal)pad and low frequency attenuation----to enable easy handling of very high sound pressure levels and the successful reduction of the pickup of low frequency ambient noise (especially common while on-stage performing) ·undistorted reproduction of high sound pressure level signals at all frequencies ·integrated three stage mesh grille---to protect the microphone from accidental damage and reduce plosives and breath noise ·standard XLR-3P(F) connector---to match all kinds of audio equipment applications: TV studios, recording studios, broadcasting stations, stage performances, percussion and guitar recording
