The Audio-Technica PRO 41 Cardioid Dynamic Handheld Microphone is a ruggedly built microphone that can withstand live performance rigors. It is optimized for vocals to produce clear, full-range reproduction. The superior internal shock mounting reduces handling noise, and its cardioid polar pattern reduces the pickup of sounds from the sides and rear, improving the isolation of the desired sound source. It is also equipped with an on/off switch, which can be locked into the on position if wanted.
