The SHURE's KSM141-SL STEREO is a pair of instrument microphone that designed for studio use but is also tough enough for live use. It is a rotating-collar dual-pattern end-addressed condenser microphone with a steady cardioid or true omnidirectional polar pattern for smooth and extremely focused sound reproduction. Besides that, it can endure exceptionally high sound pressure levels (SPL) and perfect for recording musical instruments because of its minimal self-noise and wide frequency response.
