Shure KSM137 Condenser Microphone

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.

Features:

A highly consistent cardioid polar pattern

Ultra-thin, 2.5 micron, 24 karat gold-layered, low mass Mylar(TM) 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

Features:

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

Both the acoustic environment and microphone placement strongly affect the sound obtained from miking a source. You may need to experiment with microphone placement and room treatments to achieve the best overall sound for each application.
