KSM44 Studio Microphone

The KSM44/SL is a multiple pattern (cardioid, omnidirectional, bidirectional), externally biased, dual large diaphragm condenser microphone with extremely low self-noise (7dB). Developed to meet the needs of studio recording musicians, the warm, rich sound of the KSM44 delivers exceptional performance, tailored to deliver vivid reproduction of voice for the most critical recordings. The KSM44 also offers great flexibility in a variety of recording applications, working well on acoustic and amplified instruments, as its capacity for managing high SPLs accommodates loud sound sources such as drums and guitar amplifiers.

Features

  • Dual 1-inch, externally biased, ultra-thin, 2.5 micron, 24-karat gold-layered, low mass, Mylar diaphragms provide superior transient response
  • Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response and no crossover distortion; minimizes harmonic and intermodulation distortions
  • Full-range frequency response (20 Hz - 20 KHz) for an extremely accurate reproduction of voice and instruments
  • Extremely low self noise (7 dBA) for critical studio vocal recording
  • Premium electronic components and gold-plated internal and external connectors
  • Subsonic filter eliminates rumble from mechanical vibration below 17 Hz
  • 15 dB attenuation switch for handling high input SPL sound sources
  • 3-position switchable low-frequency filter virtually eliminates unwanted background noise and controls proximity effect
  • Durable zinc die-cast housing and hardened low carbon steel grille to protect cartridge from accidental drops or misuse
  • Uniform polar response provides natural off-axis response for critical recording
  • Integrated three-stage pop protection grille to guard against wind and breath noise
  • Internal shock mount to reduce unwanted handling and stand noise
  • Replacement cartridge:  RPM130

Performance Characteristics

  • Extended frequency response
  • Very low self-noise
  • Exceptional low-frequency reproduction
  • High output level
  • High input SPL capability
  • No cross-over distortion
  • Extremely uniform polar response
  • Superior common mode rejection and suppression of radio frequency interference

Applications

The KSM44/SL is designed as a premium vocal microphone for studio recording. Microphone use, however, is a matter of personal taste. Here is a non-exhaustive list of common applications:

  • Vocals -- solo, background, voice-over
  • 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 have significant effects on the sound obtained when miking any sound source. We encourage users to experiment with these variables to achieve the best overall sound.

User Guides

SHURE MICROPHONES - Large Diaphragm

A selection of large diaphragm microphone from Shure, including cardioid, multi-pattern, and dual diaphragm models. Often found in professional recording studios, these condenser microphones deliver 'smooth and neutral' sound reproduction.


KSM32 Cardioid

Shure KSM32 offers an extended frequency response for an open, natural sounding reproduction of the original sound source. Typical applications for the KSM32 include solo, background, voice-over, and broadcasting vocals; acoustic, wind and percussive instruments; room ambience, and guitar amplification. KSM32 is a versatile microphone and one that may be used for a variety of applications other than those listed.

The class A, transformerless preamplifier circuitry eliminates cross-over distortion to give improved linearity across the full frequency range, whilst a 15dB attenuation switch allows for the handling of extremely high sound pressure levels. A switchable low-frequency filter provides greater flexibility to reduce background noise or to counteract proximity effect, and integrated three-stage pop protection grille reduces "pop" and other breath noise. The microphone has an internal shock mount to reduce the transmission of handling noise.
