Selecting Low-Frequency Response

A three-position switch on the back of the microphone lets you adjust the low-frequency response. 

Use the low-frequency filter to reduce wind noise, room noise, or proximity effect.

Flat response.

 Provides the most natural sound in most applications. 

Low frequency cutoff.

 Provides an 18 dB-per-octave 

cutoff at 80 Hz. Helps eliminate floor rumble and low-fre-

quency room noise from heating and air conditioning sys-

tems. This setting may also be used to compensate for 

proximity effect or to reduce low frequencies that make an 

instrument sound dull or muddy. 

Low frequency rolloff.

 Provides a 6 dB-per-octave roll-

off filter at 115 Hz. Use this to compensate for proximity ef-

fect or to reduce low frequencies that could make an instru-

ment sound dull or muddy. 

Setting Attenuation

The attenuation switch lets you reduce the signal level without altering the frequency response. This can 

prevent extremely loud sounds from overloading the microphone circuitry.

0 dB

 For "quiet" to "normal" sound levels. 

-15 dB

 For use with extremely loud sound sources such as drums, horns, or loud guitar cabinets. 

Load Impedance

Maximum SPL capability, output clipping level, and dynamic range vary with the input load impedance 

of the preamplifier to which you connect the microphone. Shure recommends a minimum input load 

impedance of 1000 Ω. Most modern microphone preamplifiers meet this requirement. Higher impedance 

results in better performance for these specifications. 

Integral Pop Filter

The microphone grille consists of 3 separate mesh layers that 

act as an integral pop filter. This helps reduce wind and breath 

noise. Depending on the performer, an external pop-protection 

screen or windscreen may be necessary when close-miking 

vocalists.
