OPERATION

Power

The SM86 requires phantom power. This may be supplied to the microphone from an external power supply (such as the Shure model PS1A) or directly from preamplifiers, mixers, or consoles with built-in phantom power. Suitable sources should provide 11 to 52 Vdc phantom voltage.

Impedance

A load impedance of at least 600 Ohms is recommended. The load may be as low as 150 Ohms, but a reduction in output level and output clipping level will result.

SPECIFICATIONS

Transducer Type

Condenser (electret bias)

Frequency Response

50 to 18,000 Hz (see Figure 2)

Dynamic Range (1000 Ω)

124 dB (maximum SPL to A-weighted noise level)

Signal-to-Noise Ratio

71 dB at 94 dB SPL (IEC 651)*

*S/N ratio is difference between 94 dB SPL and equivalent SPL of self– noise A-weighted.

Polarity

Positive pressure on diaphragm produces positive voltage on pin 2 relative to pin 3 of the output connector. See Figure 4.
