GENERAL DESCRIPTION
The Shure
R
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.
