Shure - KSM44A Large Diaphragm Multi-Pattern Condenser Microphone with Shockmount

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.

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 m, 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 counteracts proximity effect
• Integrated three-stage pop protection grille reduces plosives and other breath noise

Performance Characteristics
• Extremely uniform polar response
• Extended frequency response
• Minimal self-noise
• Exceptional low-frequency reproduction
• Able to withstand high SPLs
• High output level
• No crossover distortion
• Superior common-mode rejection and suppression of radio frequency interference (RFI)

Applications
The KSM44A provides superior results in any application requiring a high quality microphone. Some typical applications are listed below.
• Vocals (studio or live)
• Acoustic instruments such as piano, guitar, drums, percussion, strings
• Brass and woodwind instruments
• Low-frequency instruments such as double bass, electric bass, kick drum
• Overhead miking for drums or percussion
• Choral or orchestral ensembles
• Room ambience or stereo miking

Acoustic environments and microphone placements strongly affect the sound obtained from miking a source, especially with a high-resolution microphone like the KSM44A. You may need to experiment with placement, room treatments, and polar pattern to achieve the best overall sound for each application.
