SM137 -- Instrument Microphone
General Description
The Shure SM137 is a versatile, flat-response cardioid probe microphone with an ultra-thin diaphragm. Its fre-
quency response combines smooth high-end and tight, controlled low-end. A 15 dB pad provides natural, consis-
tent sound reproduction in both acoustic and high-volume performance applications.
Features
Performance Characteristics
•Extremely uniform polar response
•Extended frequency response
•Minimal self-noise
•Exceptional low-frequency reproduction
•Able to withstand high SPLs
•High output level
•No crossover distortion
•Superior common-mode rejection and suppression of radio frequency interference (RFI)
Applications
•Brass and woodwind instruments
•Orchestras, choirs, and wind ensembles
•Overhead miking of drums and percussion instruments
•Close-miking of acoustic instruments such as piano, guitar, violins, drums, and percussion
•Low-frequency instruments such as double bass and kick drum
•Electric guitar and bass amplifiers
•Vocals and speech
•Room ambience
Note: Sound quality is strongly affected by microphone location and room acoustics. To achieve the best overall
sound for a particular application, it may be necessary to experiment with microphone placement and room
treatments.

Mounting the Microphone
Use the supplied microphone mount with floor or boom stands. Visit www.shure.com for more mounting options:
•To reduce the pickup of unwanted low-frequency mechanical vibrations, use an isolating shock mount.
•For stereo applications, use the optional Shure A27M Stereo Microphone Adapter.
Setting Attenuation
The attenuation switch lets you reduce the signal level without altering the frequency response. This can prevent
extremely loud sounds from overloading the microphone.
0 dB For “quiet” to “normal” sound levels.
-15 dB For use with extremely loud sound sources such as drums, horns, or loud guitar
cabinets.
Integral Pop Filter
The microphone grille consists of 3 separate mesh layers that act as an integral pop filter. This helps reduce wind
and breath noise. Depending on the performer, an external pop-protection screen or windscreen may be neces-
sary when close-miking vocalists.
Load Impedance
Maximum SPL capability, output clipping level, and dynamic range vary with the input load impedance of the pre-
amplifier to which you connect the microphone. Shure recommends a minimum input load impedance of 1000 Ω.
Most modern microphone preamplifiers meet this requirement. Higher impedance results in better performance for
these specifications.
Power Requirements
This microphone requires phantom power and performs best with a 48 Vdc supply (IEC-61938). However, it will
operate with slightly decreased headroom and sensitivity with supplies as low as 11 Vdc.
Most modern mixers provide phantom power. You must use a microphone cable: XLR-to-XLR or XLR-balanced
to-TRS.
