Long -term stable 4952 outdoor microphones due to high -rotting polymer material
Hottinger Brüel & Kjær
About This Product
The 4952 type outdoor microphone is suitable for long -term use outdoors. 4952 Type Outdoor Microphone exterior parts are made of polymer material with very high corrosion resistance. With the use of this polymer material and the excellent long -term stability of microphones, it is possible to operate outdoors for at least one year without significant changes in sensitivity.
The frequency characteristics are controlled by linear technology and meet the requirements of IEC 61672 Class 1. The upper windscreen and bird spikes (birds) can be removed in a few seconds and can be easily calmed down the microphone. Also, because it is lightweight, it is suitable for using it with a mobile phone.
■ Use
