The�KSM137/SL�from�Shure�is a cardioid condenser studio microphone designed for instrument recording and sound reinforcement. The KSM137/SL offers a wide frequency response of 20 Hz to 20 kHz, making it a flexible microphone for a variety of applications. The KSM137/SL features a cardioid element and permanently biased transducer design that results 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. The tight cardioid pattern is effective in attenuating off-axis signal due to room environment, instruments, monitor noise, etc. The Shure KSM137/SL is a cardioid condenser studio microphone designed for instrument recording and sound reinforcement.
