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.
