SHURE KSM137SL Details
KSM137/SL with foam windscreen and carrying case, champagne finish
KSM137
The Shure KSM137 is an end-address condenser microphone with a cardioid polar pattern. Designed for studio use, yet rugged enough for live applications, the KSM137 can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording musical instruments.
Performance Characteristics
Extended frequency response
Low self noise
Exceptional reproduction of low-frequency sounds
Can withstand high sound pressure levels (SPL)
High output level
No crossover distortion
Uniform polar response
Superior common mode rejection and suppression of radio frequency interference
Applications
Some typical applications for the KSM137 are listed below. Microphone use, however, is a matter of personal taste. The KSM137 may be used for a variety of applications other than those listed.
Acoustic instruments -- such as piano, guitar, drums, percussion, strings
Wind instruments -- brass and woodwind
Low frequency instruments -- such as double bass, electric bass, kick drum
Overhead miking -- drums or percussion
Ensembles -- choral or orchestral
Room ambiance pick-up -- guitar amplifier or drums
