The Shure KSM141/SL is a dual-pattern end-addressed condenser microphone with a rotating collar, allowing easy switching between a consistent cardioid or true omnidirectional polar pattern for smooth and extremely focused sound reproduction.Designed for studio use, yet rugged enough for live applications, the KSM141/SL can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response makes it ideal for recording musical instruments. A mechanical polar pattern switch for highly consistent cardioid and true omnidirectional polar patterns; provides flexibility in a wide variety of recording applications Ultra-thin, 2.5 micron, 24 karat gold-layered, low mass Mylar diaphragm for superior transient response Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response, no crossover distortion, and minimal harmonic and intermodulation distortion Premium electronic components, including gold-plated internal and external connectors Subsonic filter eliminates low frequency rumble (less than 17 Hz) caused by mechanical vibration Three-position switchable pad (0 dB, 15 dB, and 25 dB) for handling extremely high sound pressure levels (SPLs) Three-position switchable low-frequency filter to reduce background noise and counteract proximity effect Champagne finish Foam windscreen and carry case includedCheck out Shure’s Listening Lab to get the lowdown on this and every other Shure mic!
