Shure KSM44A Multipattern Condenser Mic Features:
- Prethos Advanced Preamplifer Technology: Class A, discrete, transformerless preamplifier provides transparency, extremely fast transient response and no crossover distortion, as well as minimizes harmonic and intermodulation distortions
4dB of self-noise and max SPL of 131dB for a total dynamic range of 127dB—an increase of 7dB for cleanly nuanced audio capture
Multiple polar patterns-cardioid, omnidirectional and bidirectional—for maximum flexibility in a wide variety of recording applications
Dual 1", externally biased, ultra-thin, 2.5µm, 24 Karat gold-layered, low-mass diaphragms provide superior frequency response
Premium electronic components and gold-plated internal and external connectors
Subsonic filter eliminates rumble from mechanical vibration below 17Hz
Switchable 15dB pad for handling extremely high sound pressure levels (SPLs)
3-position switchable low-frequency filter helps reduce unwanted stand vibration noise or counteract proximity effect
Integrated three-stage "pop" protection grille reduces plosives and other breath noise
Includes ShureLock Suspension Shock Mount, ShureLock Stand Mount, carrying case, and velveteen pouch
