The supplied rain protection tube is inteded for protecting the
microphone and the XLR cable connector against direct rain.

Note that the installed tube will slightly affect the frequency
response and the polar pattern of the microphone. This effect
can be minimized by adjusting the tube in such a way that there
is only a short canopy (about 10 mm) in front of the microphone
capsule.

The rain protection tube for the CM16/CMPA microphone can
also be combined with the microphone heating.
