KSM44A on August 18, 2015 | Marketing Team Multi-Pattern Dual Diaphragm Microphone Premium microphone with three polar pattern options (cardioid, omnidirectional, bidirectional). 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 andPrethos® 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 Preamplifier 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 μm, 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
