Description
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
Featuring integral pop protection and shock-mounting plus a multipattern true condenser capsule and transparent Class-A circuitry with ultralow self-noise, the Shure KSM44A/SL large-diaphragm microphone is built to deliver excellent transient response, neutral tone, and the flexibility to handle most sound sources and mic configurations. Its flat frequency response and selectable settings—two low-cut filter options and a -15 dB pad—make the KSM44A/SL honest and versatile, so it can be used on anything from vocals and guitars to drums and piano.
The cardioid, omnidirectional, and figure-8 polar patterns of the KSM44A/SL allow it work optimally as a close mic, room mic, or single mic for multiple instruments. The built-in pop protection utilizes three separate layers to minimize noise from vocal plosives, breaths, and even light wind. Internal shock-mounting helps to decouple the mic from sources of vibration that could otherwise transfer from the mic body to the capsule. Being a solid-state XLR condenser mic, the KSM44A/SL requires 48V phantom power. Since it comes with a ShureLock shockmount, ShureLock swivel adapter, velveteen pouch, and hard shell carrying case, it is equally ready for the studio and the stage.
- 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
