The Shure KSM141/SL Small Diaphragm Microphone is a dual pattern instrument microphone that delivers exceptional flexibility and refined sonic accuracy for professional recording and live sound applications.
Designed for engineers and musicians who need one microphone that can adapt to multiple recording situations, the KSM141/SL features switchable cardioid and omnidirectional polar patterns, making it equally comfortable capturing intimate acoustic instruments, spacious room ambience, percussion, piano, strings, choirs, and more. At the heart of the KSM141/SL is a dual-diaphragm design with an ultra-thin, 2.5 micron, 24 karat gold-layered Mylar diaphragm that provides fast transient response, natural detail, and remarkably consistent off-axis performance. Its Class A, transformerless preamp circuitry delivers transparent, low-noise operation while maintaining the depth and realism critical for professional studio work. The KSM141/SL is built to handle demanding recording environments with ease. A switchable attenuation pad allows the microphone to capture high-SPL sources without distortion, while the selectable low-frequency filter helps reduce unwanted rumble and proximity effect. Whether you need focused cardioid precision or open, natural omni capture, the KSM141/SL offers the versatility and performance that make it a valuable addition to any microphone locker.
