• Snap-fit foam windscreen
• RF filtering
MX400 microphones are available with 305 mm (12 in.) or 457 mm (18 in.)

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.
Microflex microphones use interchangeable
cartridges that allow you to choose the polar
pattern for different installations.
