Shure KSM9 Hypercardioid/Subcardioid Condenser Microphone in Black

Features Dual 3/4 gold layered, low mass Mylar® diaphragms provide superior frequency response. Dual polar patterns (Hypercardioid and subcardioid) for even greater flexibility in demanding performance applications. Class A, discrete, transformerless preamplifier provides transparent, extremely fast transient response with no crossover distortion and minimal harmonic and intermodulation distortion. Advanced suspension shock mount system that isolates cartridge from handling and stand noise. Premium electronic components, including gold-plated internal and external connectors. Three-stage grille reduces “pop” and breath noise. Also available as ULX-D® and QLX-D™ digital wireless handheld transmitters and Axient® and UHF-R® wireless handheld transmitter SKUs Specifications Cartridge Type: Condenser (Electret Biased) Frequency Response: 50 to 20,000 Hz Output Impedance: 145 ohms (actual) Phantom Power: 48 Vdc ± 4 Vdc (IEC-268-15/DIN 45 596), positive pins 2 and 3 Current Drain: 5.2 mA typical at 48 Vdc Common Mode Rejection: >60 dB, 50 Hz to 20 kHz Polarity: Positive pressure on front diaphragm produces positive voltage on output pin 2 relative to pin 3 Polar Patterns: Hypercardioid, Subcardioid Sensitivity (typical; at 1000 Hz;1 Pa = 94 dB SPL): Hypercardioid: -50.5 dBV/Pa / Subcardioid: -53.0 dBV/Pa Self-noise (typical, equivalent SPL; A-weighted, IEC 651): Hypercardioid: 20.7 dB / Subcardioid: 22.7 dB Maximum SPL @ 1000 Hz 2500 ohms load: Hypercardioid: 150.8 dB / Subcardioid: 153.0 dB 1000 ohms load: Hypercardioid: 150.9 dB / Subcardioid: 153.1 dB Output Clipping Level* 2500 ohms load: 7.0 dBV 1000 ohms load: 6.4 dBV Dynamic Range (@ 1 kHz) 2500 ohms load: Hypercardioid: 130.8 dB / Subcardioid: 130.1 dB 1000 ohms load: Hypercardioid: 130.1 dB / Subcardioid: 130.6 dB Signal to Noise ratio: Hypercardioid: 73.3 dB / Subcardioid: 71.3 dB Dimensions and Weight: 49 mm (1 15/16 in.) maximum body diameter, 191 mm (7.5 in.) long 300 grams (10.6 oz.)
