BM-81m - Small Diaphragm Instrument Condenser Microphone


BM-81m is a professional condenser microphones, it adopt pressure gradient transducer cartridge, with a vapor-deposited gold diaphragm, the mics have cardioid polar pattern. The mic have characteristics of high sensitivity, wide frequency response, small distortion, low self-noise, clear and natural sound quality, effective function of reducing the feedback sound. The housings of BM-81m are spray-painted metal-die casting housings, with standard XLR connector, the mic can match with all kinds of audio equipments.
