KSM137

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.

Performance Characteristics

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

Features

A 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)
Three-position switchable pad (0 dB, 15 dB, and 25 dB) for handling extremely high sound pressure levels (SPLs)
Three-position switchable low-frequency filter reduces background noise and counteracts proximity effect

Directional Polar Pattern: Cardioid/Omnidirectional
Output Impedance: 150 ohms (actual)
Attenuation Switch: 0 dB,15 dB, or 25 dB attenuation
Low Frequency Response Switch: Flat; -6 db/octave below 115 Hz;; -18 dB/octave below 80 Hz
Phantom Power: 48 Vdc +/- 4 Vdc (IEC26815/DIN 45 596), positive pins 2 and 3
Current Drain: 4.65 mA typical at 48 Vdc
Common Mode Rejection: >50 dB, 20 Hz to 20 kHz
Polarity: Positive pressure on diaphragm produces positive voltage on output pin 2 relative to pin 3
Dimensions and Weight: 20 mm (0.8 in.) diameter, 146 mm (5.75 in.) long;; 156 grams (5.5 oz.)
Sensitivity (typical, at 1000 Hz; 1 Pa = 94 dB SPL): -37 dBV/Pa
Selfnoise (typical, equivalent SPL; A-weighted, IEC 651): 14 dB
Maximum SPL: 5000 ohm load (Attenuator on): 145 (160, 170) dB; 2500 ohm load (Attenuator on): 139 (154, 164) dB; 1000 ohm load (Attenuator on): 134 (149, 159) dB
Output Clipping Level*: 5000 ohm load: 15 dBV; 2500 ohm load: 9 dBV; 1000 ohm load: 3 dBV
Dynamic Range: 5000 ohm load: 131 dB; 2500 ohm load: 125 dB; 1000 ohm load: 120 dB
Signal to Noise Ratio**: 80 dB
*20 Hz to 20 kHz; THD < 1%. THD of the microphone preamplifier when applied input signal is equivalent to the cartridge output at specified SPL.
**S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted.
