KSM137

General Description

The KSM137 is a premium, end-address,
condenser microphone with a cardioid polar
pattern engineered for highly critical studio re-
cording and live sound productions. Its class A,
discrete, transformerless preamplifier provides
extremely transparent sound capture, and a
three position switchable pad and low-cut filter
allows for handling of extremely high sound
pressure levels (SPL) and controlled bass
response. Versatile, durable, and precise, the
KSM137 is an outstanding microphone for both
live and studio applications.
Features
• A highly consistent cardioid polar pattern
• Ultra-thin, 2.5 μm 24-karat gold-layered,
low-mass Mylar

transient response
• Class A, discrete, transformerless
preamplifier for transparency, extremely fast
transient response, no crossover distortion,
and minimal harmonic and inter-modulation
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
• Three-position attenuation switch (0 dB, 15
dB, and 25 dB) for handling extremely high
SPLs
• Three-position low-frequency filter
switch reduces stand vibration noise and
counteracts proximity effect

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)

Model Variations

This microphone can be purchased as a stereo
pair (KSM137/SL STEREO). In addition to the
standard accessories, the stereo pair includes
a stereo stand adapter (A27M) for mounting
two microphones on one stand.
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 experi-
ment with microphone placement and room
treatments.
