SPECIFICATIONS
USING THE FOAM WINDSCREEN
The foam windscreen, supplied with the CM-2S, fits over the grill portion of the microphone and is designed primarily to decrease bass
rumble (from wind noise pickup) during outdoor live or recording use. It is also useful in keeping mouth spray out of the microphone
head. (Note: Be aware that the foam windscreen will slightly attenuate the high frequency response of the microphone.)
(WARNING: The capsule is the heart of the condenser microphone. If the elements become
s dirty or wet, the sound will be degraded.
Never spray any liquid on the microphone head. Always use a foam windscreen or pop filter if you talk or sing close to the microphone
grill screen.)
