The KSM137 is an end-address condenser microphone with a single 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. Versatile, durable, and precise, the KSM137 is an outstanding microphone for instruments ranging from percussion to wind, strings to brass, and piano to guitar. Features
Performance Characteristics
Applications Some typical applications for the KSM137 are listed below. Microphone use is a matter of personal taste and the KSM137 may be used for a variety of applications other than those listed.
Specifications Cartridge Type Permanently Biased Condenser Frequency Response 20 to 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 (IEC26815/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 Selfnoise (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 *20 Hz to 20 kHz; THD < 1%. THD of the microphone preamplifier when applied input signal is equivalent to the cartridge output at specified SPL **S/N ratio is difference between 94 dB SPL and equivalent SPL of self noise A-weighted. |
