Descriere

The Shure KSM137 is a versatile, durable, and precise single cardioid polar pattern instrument microphone. The Shure KSM137 is an end-address condenser microphone with a cardioid polar pattern. Designed for studio use, yet rugged enough for live applications, the KSM137 can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording musical instruments. Features A highly consistent cardioid polar pattern Ultra-thin, 2.5 micron, 24 karat gold-layered, low mass Mylar diaphragm for superior transient response Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response, no crossover distortion, and minimal harmonic and intermodulation distortion Premium electronic components, including gold-plated internal and external connectors Subsonic filter eliminates low frequency rumble (less than 17 Hz) caused by mechanical vibration Three-position switchable pad (0 dB, 15 dB, and 25 dB) for handling extremely high sound pressure levels (SPLs) Three-position switchable low-frequency filter reduces background noise and counteracts proximity effect Low self-noise Exceptional reproduction of low-frequency sounds Superior common mode rejection and suppression of RFI (radio frequency interference) Great for Close miking of acoustic instruments such as piano, guitar, violins, drums, and percussion; Overhead miking of drums and percussion instruments; Electric guitar amplifiers; Brass and woodwind instruments; Room ambience pick-up (guitar amplifier or drums); Orchestras, choirs, wind ensembles; Low-frequency instruments such as double bass and kick drum A137C Carrying Case, A100WS Windscreen and A57F Stand Mount included with this microphone Specifications: Cartridge Type: Permanently Biased Condenser Frequency Response: 20-20,000 Hz Directional Polar Pattern: Cardioid Output Impedance: 150 Ohms (actual) Attenuation Switch: 0 dB,15 dB, or 25 dB attenuation Low Frequency Response Switch: Flat; -6 db/octave below 115 Hz; -18 dB/octave below 80 Hz Phantom Power: 48 Vdc+/- 4 Vdc (IEC-268-15/DIN 45 596), positive pins 2 and 3 Current Drain: 4.65 mA typical at 48 Vdc Common Mode Rejection = 50 dB, 20 Hz to 20 kHz Polarity: Positive pressure on diaphragm produces positive voltage on output pin 2 relative to pin 3 Dimensions and Weight: 20 mm (0.8 in.) diameter, 122 mm (4.8 in.) long; 100 grams (3.5 oz.) Sensitivity (typical, at 1000 Hz; 1 Pa = 94 dB SPL): -37 dBV/Pa Self-noise (typical, equivalent SPL; A-weighted, IEC 651): 14 dB Maximum SPL at 1 kHz: 5000 Ohm load (Attenuator on): 145 (160, 170) dB, 2500 Ohm load (Attenuator on): 139 (154, 164) dB, 1000 Ohm load (Attenuator on): 134 (149, 159) dB Output Clipping Level: 5000 Ohm load: 15 dBV, 2500 Ohm load: 9 dBV, 1000 Ohm load: 3 dBV Dynamic Range: 5000 Ohm load: 131 dB, 2500 Ohm load: 125 dB, 1000 Ohm load: 120 dB Signal to Noise Ratio: 80 dB Manufacturer information Shure Europe GmbH Jakob-Dieffenbacher-Str....
