GENERAL DESCRIPTION
The ShureR 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.
FEATURES
SA highly consistent cardioid polar pattern
SUltra-thin, 2.5 µm, 24 karat gold-layered, low mass MylarR diaphragm for superior transient response
SClass A, discrete, transformerless preamplifier for transparency, extremely fast transient response, no crossover distortion, and minimal harmonic and intermodulation distortion
SPremium electronic components, including gold-plated internal and external connectors
SSubsonic filter eliminates low frequency rumble (less than 17 Hz) caused by mechanical vibration
SThree-position switchable pad (0 dB, 15 dB, and 25 dB) for handling extremely high sound pressure levels (SPLs)
SThree-position switchable low-frequency filter reduces background noise and counteracts proximity effect
