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.
• Snap into the groove below the cartridge.
• To remove, spread the gap with a screwdriver
or thumbnail.
• Provides 30 dB of "pop" protection.
