Consistent cardioid polar pattern and special low-mass Mylar diaphragm provides better transient response.

The KSM137 is an end-address condenser microphone with a single 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 instruments.

Versatile, durable, and precise, the KSM137 is an outstanding microphone for instruments ranging from percussion to wind, strings to brass, and piano to guitar.

Shure KSM137 Cardioid Condenser Mic Features:

• Highly consistent cardioid polar pattern
• Ultra-thin, 2.5 micron, 24 karat gold-layered, low mass Mylar diaphragm for superior transient response
• Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response, no crossover distortion, and minimal harmonic and intermodulation distortion
• Premium electronic components, including gold-plated internal and external connectors
• Subsonic filter eliminates low frequency rumble (less than 17Hz) caused by mechanical vibration
• Switchable 15dB pad for handling extremely high sound pressure levels (SPLs)
• 3-position switchable pad (0dB, 15dB, and 25dB) for handling extremely high-sound pressure levels (SPLs)
• 3-position switchable low-frequency filter reduces background noise and counteracts proximity effect
  
  Performance Characteristics
