Outdoor Microphone Types 4952 and 4952-A

Outdoor Microphones Types 4952 and 4952-A are suitable for long periods of unattended outdoor use. Their exterior housing is made of a chemical resistant polymer that provides extremely high protection against corrosion.

The microphones' long-term stability guarantees unattended outdoor use for up to a year without any significant change in 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.

Low weight makes this an ideal choice for portable use.
