Overview
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
