Shure

collapse expand iconDescription

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

SM137 Condenser Microphone
  • Cartridge Type: Permanently Biased Condenser
  • Frequency Response: 20 to 20,000Hz
  • Directional Polar Pattern: Cardioid
  • Output Impedance: 150? (actual)
  • Attenuation Switch (0dB or 15dB attenuation) 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: >50dB, 20Hz to 20kHz
  • Polarity: Positive pressure on diaphragm produces positive voltage on output pin 2 relative to pin 3
  • Dimensions: 24mm (0.950") diameter, 162mm (6.375") long
  • Weight: 195g (6.9oz..)
  • Sensitivity (typical, at 1000Hz; 1 Pa = 94dB SPL): -41dBV/Pa
  • Self-noise (typical, equivalent SPL; A-weighted (IEC 651)): 19dB
  • Maximum SPL@ 1000Hz:
  • 5000? load (Attenuator on): 150 (165dB)
  • 2500? load (Attenuator on): 144 (159)dB
  • 1000? load (Attenuator on): 139 (154dB)
  • Output Clipping Level*:
  • 5000? load: 15dBV
  • 2500? load: 9dBV>
  • 1000? load: 3dBV
  • *20Hz to 20kHz; THD < 1%. THD of the microphone preamplifier when applied input signal is equivalent to the cartridge output at specified SPL.
    Dynamic Range (Attenuator On):
  • 5000? load: 133 (136)dB
  • 2500? load: 128 (130dB)
  • 1000? load: 122 (125)dB
  • Signal to Noise Ratio**
  • 75dB
  • **S/N ratio is difference between 94dB SPL and equivalent SPL of self-noise A-weighted

    My favorite mic in the studio was always the Shure BG 4.0, but when it shot south, I knew that I could never be happy with anything less. If I could find one not-battery-operated, even better. The SM 137 exceeded my expectations. Noise-free, clear, natural sound. I expected to get the most advantage from my acoustic guitar, but this afternoon I used it in tandem with an SM 58 to record amplified electric. Wow. What I've been missing the last few years. It helps that I am finally recording in 24 bits, but still. I'm quite happy.

  • Easter Choir Miking

    Used this mic along with another one that I already owned to mic a 20 person choir on Easter morning. Our contemporary Praise and Worship band usually runs around 98 db on stage so I was worried that I wouldn't be able to get the choir above the music. I was wrong. The mics have a tight focused pattern that let me really zero in on the choir without picking up a lot of stage noise. My gain before feedback was great with hardly a squeak of feedback and I had to really push them to get that. Didn't use much eq at all. On of the best small diaphram mics I have ever used. The other one I already owned, I used as a drum overhead. Worked very well in that position too.
