Shure KSM137/SL Cardioid Condenser Instrument Microphone w/ Foam Windscreen and Carrying Case (Champagne)

Shure KSM137/SL Cardioid Condenser Instrument Microphone w/ Foam Windscreen and Carrying Case (Champagne)
Camcor Item No.	136017335
Mfg. Part No.	KSM137/SL

Shure KSM137/SL instrument microphone cardioid condenser microphone offers smooth and extremely focused reproduction of the original sound source. Its low self-noise and extended frequency response make it ideal for recording instruments. Versatile, durable, and precise, KSM137/SL is ideal for a wide range of instruments ranging from percussion to wind, strings to brass, and piano to guitar.

The KSM137/SL is an end-address condenser microphone with a single cardioid polar pattern. Designed for studio use, yet rugged enough for live applications, the KSM137/SL can withstand extremely high sound pressure levels (SPL).

Includes KSM137/SL, case, windscreen, clip, and user guide. Champagne color.

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 17 Hz) caused by mechanical vibration

Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs)

3-position switchable pad (0 dB, 15 dB, and 25 dB) for handling extremely high sound pressure levels (SPLs)

3-position switchable low-frequency filter reduces background noise and counteracts proximity effect

Extended frequency response

Exceptional reproduction of low-frequency sounds

Can withstand high sound pressure levels (SPL)

Superior common mode rejection and suppression of radio frequency interference

Foam windscreen

Carrying case

Champagne finish
