Multi-Pattern Dual Diaphragm Microphone
The Shure KSM Microphone Series
KSM 44A is a premium, large-diaphragm, side-address condenser microphone with multiple polar pattern options (cardioid, omnidirectional, bidirectional). The refined and sophisticated design of the KSM-44A features an externally biased, dual 1-inch diaphragms, extensive internal pop filtering and Prethos® Advanced Preamplifier Technology for a ground-breaking threshold minimum of self-noise. The KSM44A is the premier choice for the highest level of professional studio and stage performance.
A milestone achievement in sound reinforcement, Prethos Advanced Preamplifier Technology employs transparent internal circuitry architectures that enable unprecedented audio quality and performance.
→ A milestone technical achievement, Shures Prethos Advanced Preamplifier Technology provides 4dB of self-noise and max SPL of 131 dB for a total dynamic range of 127 dB an increase of 7 dB that defines the new standard for cleanly nuanced audio capture→ Multiple polar patternscardioid, omnidirectional and bidirectionalfor maximum flexibility in a wide variety of recording applications→ Dual 1 inch, externally biased, ultra-thin, 2.5 µm, 24 Karat gold-layered, low mass diaphragms provide superior transient response→ Class A, discrete, transformerless preamplifier for transparency, extremely wide frequency response and no crossover distortion. Minimizes harmonic and intermodulation distortions→ Premium electronic components and gold-plated internal and external connectors→ Subsonic filter eliminates rumble from mechanical vibration below 17 Hz→ Switchable 15 dB 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
