The exterior housing of Outdoor Microphones Types 4952 and 4952-A is made of a chemical resistant polymer that provides extremely high protection against corrosion. This - and the microphones’ excellent long-term stability - guarantee outdoor use for at least a year with no significant change in measuring sensitivity.
Frequency response is precisely controlled, such that, with the appropriate linearization, IEC 61672 Class 1 requirements are fulfilled.
The windscreen upper part and bird spike can be removed in seconds, enabling easy acoustical calibration of the microphone.
