The Audio-Technica ATM350U is a small-diaphragm condenser mic, with a cardioid polar pattern that ships with a universal clip-on mounting system. The mic itself, fits snugly into the windshield affixed to a 5-inch goose-neck style boom-arm. The ATM350U is capable of handling very high SPL, making it an ideal choice for live applications. The mic can literally be clipped-on via the peg style clip, to any compatible sound source. These include viola’s, violin’s, brass and woodwind instruments.
