The KSM141/SL from Shure is a switchable-polar-pattern condenser studio microphone designed for instrument recording and sound reinforcement. The capsule’s pattern is switchable between omnidirectional and cardioid pick up. Omnidirectional offers a more generous pickup area while cardioid offers attenuation of noise and ambiance at the off-axis sections of the microphone. In addition, the microphone offers a wide 20 Hz to 20 kHz frequency response making it a flexible solution for a variety of applications. The KSM141/SL’s element features a permanently biased transducer design resulting in clean, accurate signal reproduction and frequency response. The transformerless Class-A output circuitry provides a noise-free-output signal path while maintaining high gain levels.

There is a 3-position low-frequency roll-off switch, eliminating low-frequency rumble noise and counteracting proximity effect. The KSM141/SL handles high sound-pressure levels and features a 3-position pad switch providing attenuation at 0, 15, 25 dB. This allows for confident miking of instruments high in transient response such as drums, percussion, and brass. The microphone is also suitable for recording piano, strings, guitar, and woodwinds. The KSM141/SL ships with a case, a microphone clip, and a foam windscreen.
