The Shure KSM141/SL is a dual-pattern condenser instrument microphone featuring a mechanical polar pattern switch that allows easy transition between cardioid and true omnidirectional modes. With its ultra-thin 24K gold-layered Mylar diaphragm, transformerless preamplifier, extended frequency response, and low self-noise, the KSM141 is ideal for both studio recording and live applications.

It handles extremely high SPLs with a three-position pad and includes a subsonic filter to eliminate low-frequency rumble caused by mechanical vibrations.
