Studiový kondenzátorový mikrofon, kardioidní charakteridtika. SM 137 má ultralehkou membránu pro dobrý frekvenční rozsah, který kombinuje hladné výšky s pevnými basy. Snáší vysoký akustický tlak.

The SM137 is a versatile, flat-response cardioid condenser probe microphone. 

The SM137 has an ultra-thin diaphragm for a frequency response that combines a smooth high-end with a tight, controlled low-end and a 15db pad for natural sound reproduction in both acoustic and high volume performance applications. 

  • Ultra-thin diaphragm for smooth high end and tight, controlled low end
     
  • 15dB pad for performance consistency across a wider range of high SPL sources
     
  • Low self-noise and transformerless preamplifier circuitry
Cartridge Type

162 mm (6.375 in.) long
195 grams (6.9 oz.)
Sensitivity (typical, at 1000 Hz; 1 Pa = 94 dB SPL)
-41 dBV/Pa
Self-noise (typical, equivalent SPL; A-weighted (IEC 651))
19 dB
Maximum SPL@ 1000 Hz
5000 ohms load (Attenuator on): 150 (165 dB)
2500 ohms load (Attenuator on): 144 (159) dB
1000 ohms load (Attenuator on): 139 (154 dB)
Output Clipping Level*
5000 ohms load: 15 dBV
2500 ohms load: 9 dBV>
1000 ohms load: 3 dBV
*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.
