Shure KSM137/SL Condenser Mic
Product Description for the Shure KSM137/SL Condenser MicThe Shure KSM137/SL is a cardioid condenser studio microphone designed for instrument recording and sound reinforcement. The microphone offers a wide 20Hz-20kHz frequency response making it a flexible microphone for a variety of applications. The KSM137/SL features a cardioid element and permanently biased transducer design resulting in clean, accurate signal reproduction and frequency response. The transformer-less, 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 ambiance, instruments, monitor noise etc.There is a 3-position low frequency roll-off switch, eliminating low frequency rumble noise and counteracts proximity effect. The KSM137/SL handles high sound pressure levels and features a 3-position Pad switch providing attenuation at 0dB, 15dB and 25dB. This allows confident miking of instruments high in transient response such as drums, percussion, and brass. the microphone is suitable for piano, strings, guitar, and woodwind as well.
The cardioid polar pattern is effective in attenuating off-axis signal due to room ambiance, instruments, monitor noise etc.
