The KSM44A/SL Side-Address Condenser Vocal Microphone from Shure is a large-diaphragm, side-address condenser microphone with multiple polar pattern options, including cardioid, omnidirectional, and figure-8. The KSM44A features an externally biased, dual 1" diaphragm, extensive internal pop filtering and Prethos Advanced Preamplifier Technology for low self-noise.

Prethos Advanced Preamplifier Technology provides 4 dB of self-noise and max SPL of 131 dB for a total dynamic range of 127 dB
Multiple polar patterns including cardioid, omnidirectional and figure-8 for flexibility in a wide variety of recording applications
Dual, 1" externally biased, ultra-thin, 2.5 μm, 24K gold-layered, low mass diaphragms provide superior transient response
Class A, discrete, transformerless preamplifier for transparency, extremely wide frequency response and no crossover distortion, minimizing harmonic and intermodulation distortions
Subsonic filter eliminates rumble from mechanical vibration below 17 Hz
Switchable 15 dB pad for handling extremely high sound pressure levels (SPL)
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
