The Shure BETA 57A is a high output supercardioid dynamic microphone designed for professional sound reinforcement and project studio recording. It maintains a true supercardioid pattern throughout its frequency range (50-16,000 HZ). This insures high gain-before-feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration. Excellent for acoustic and electric instruments as well as for vocals, the versatile Beta 57A provides optimal warmth and presence. Some vocalists like this mic as it provides great feedback rejection -- perfect for situations on loud stages where it is hard to isolate signals.
