- Cardioid Polar Pattern
- Picks up the most sound in front of the microphone and some from the sides. Less susceptible to feedback in high volume environments.
- Adjustable Frequency Response
- Interchangeable frequency response caps for mild and high boosts.

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
- Permanently Biased Condenser
- Frequency Response
- 20 to 20,000 Hz
View Larger - Directional Polar Pattern
- Cardioid
- Output Impedance
- 150 ohms (actual)
- Attenuation Switch
- 0 dB or 15 dB 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
- >50 dB, 20 Hz to 20 kHz
- Polarity

- Dimensions and Weight
- 24 mm (0.950 in.) diameter
- 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.
- Dynamic Range (Attenuator On)
- 5000 ohms load: 133 (136) dB
- 2500 ohms load: 128 (130 dB)
- 1000 ohms load: 122 (125) dB
- Signal to Noise Ratio**
- 75 dB
- **S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted.
