Description
The KSM137/SL from Shure is a cardioid condenser studio microphone designed for instrument recording and sound reinforcement. The KSM137/SL offers a wide 20 Hz to 20 kHz 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 counteracting proximity effect. The KSM137/SL handles high sound pressure levels and features a 3-position pad switch providing attenuation at 0 dB, 15 dB and 25 dB. This allows confident miking of instruments high in transient response such as dru
