The Outdoor Microphone Nor1214 is a measurement microphone for all-weather conditions. It is intended for temporary as well as permanent outdoor applications.
The microphone system is well protected from rain, snow, dust and insects, satisfying IP 55 requirements.
Further, compared to a standard measurement microphone, the Outdoor Microphone Nor1214 improves the measurement accuracy by reducing the wind noise and by improving the directional response for sound from different directions.
Combined with a suitable sound level instrument like Nor140, the Outdoor microphone Nor1214 satisfy Class 1 specification requirements according to IEC61672-1 and related national standards.
The microphone is intended for vertical mounting only since the act of gravitation forms a part of the rain protection system. The reference direction may, however, be selected to be vertical or horizontal based on the applied frequency compensation.
