Shure KSM44A Large Diaphragm Multi-Pattern Condenser KSM44A/SL

Shure's 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. The KSM44A/SL includes ShureLock® suspension shock mount, ShureLock® stand mount, carrying case, and velveteen pouch.IncludesKSM44A Large Diaphragm Multi-Pattern Condenser MicrophoneShureLock Stand MountZippered Carrying CaseShureLock® Elastic Shock MountSuspension Shock Mount Elastic Cord, Cristal (contains two)Protective Velveteen PouchFeaturesA milestone technical achievement, Shure’s 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 captureMultiple polar patterns–cardioid, omnidirectional and bidirectional–for maximum flexibility in a wide variety of recording applicationsPremium electronic components and gold-plated internal and external connectorsSubsonic filter eliminates rumble from mechanical vibration below 17 Hz.Switchable 15 dB pad for handling extremely high sound pressure levels(SPLs)Dual 1 inch, externally biased, ultra-thin, 2.5 µm, 24 Karat gold-layered, low mass diaphragms provide superior transient responseClass A, discrete, transformerless preamplifier for transparency, extremely wide frequency response and no crossover distortion. Minimizes harmonic and intermodulation distortions.3-position switchable low-frequency filter helps reduce unwanted stand vibration noise or counteract proximity effectIntegrated three-stage "pop" protection grille reduces plosives and other breath noiseSpecificationsType: Dual-Diaphragm, Externally-Biased CondenserPolar Pattern (selectable): Cardioid, Omnidirectional, BidirectionalFrequency Response: 20 to 20,000 HzOutput Impedance: 50 ΩSensitivity, open circuit voltage, @ 1 kHz, typical:Cardioid: –31 dBV/Pa[1] (29.8 mV)Omnidirectional: –37 dBV/Pa[1] (14.8 mV)Bidirectional: –36 dBV/Pa[1] (16.8 mV)Maximum SPL, 1 kHz at 1% THD:CardioidPad Off, 2500 Ω load: 134 dBPad Off, 1000 Ω load: 131 dBPad On, 2500 Ω load: 150 dBPad On, 1000 Ω load: 147 dBOmnidirectionalPad Off, 2500 Ω load: 140 dBPad Off, 1000 Ω load: 137 dBPad On, 2500 Ω load: 152 dBPad On, 1000 Ω load: 149 dBBidirectionalPad Off, 2500 Ω load: 139 dBPad Off, 1000 Ω load: 136 dBPad On, 2500 Ω load: 151 dBPad On, 1000 Ω load: 148 dBSignal-to-Noise RatioCardioid: 90 dBOmnidirectional: 88 dBBidirectional: 86.5 dBDynamic Range @ 1 kHzCardioid2500 Ω load:
