Shure KSM44A Multi-Pattern Dual Diaphragm Microphone

Multi-Pattern Large Dual-Diaphragm Side-Address Condenser Microphone

The KSM44A is a premium, large-diaphragm, side-address condenser microphone with multiple polar pattern options (cardioid, omnidirectional, bidirectional). The refined and sophisticated design of the KSM44A 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.

Features:

• Prethos Advanced Preamplifer Technology: Class A, discrete, transformerless preamplifier provides transparency, extremely fast transient response and no crossover distortion. Minimizes harmonic and intermodulation distortions.
• Groundbreaking specifications: 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 patterns-cardioid, omnidirectional and bidirectional-for maximum flexibility in a wide variety of recording applications
• Dual 1 inch, externally biased, ultra-thin, 2.5 mum, 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 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
