impractical.

Snap-Fit Windscreen
• Snap into the groove below the cartridge.
• To remove, spread the gap with a screwdriver or thumbnail.
• Provides 30 dB of "pop" protection.
Microphone Placement
• Aim the microphone toward the desired source, such as the talker.
• Aim it away from any unwanted source, such as a loudspeaker.
• Place the microphone within 15 to 30cm (6 to 12 in.) of the desired
sound source.
• Always use the supplied windscreen or optional metal windscreen to
control breath noise.
• If four or more microphones will be open at the same time, use of
an automatic mixer, such as the Shure SCM810 or SCM410, is
recommended.
Securing to a Surface
Drill two holes in the mounting surface 50.8 mm (2 in.) apart.
Use #6-32 screws to secure the microphone.
