Effective Protection in Outdoor Environments
Both Outdoor Microphone Unit Type 4198 and Outdoor Microphone Kit UA-1404 use the same protective assembly.
Effective Wind Protection
The windscreen reduces wind noise by approximately 15 dB for wind speeds up to 120 km/h. It is made of a specially prepared porous polyurethane foam, which is resistant to corrosive atmospheres and immune to moisture.
Effective Rain Protection
A rain cover protects the microphone from moisture. The cover surrounds the microphone cartridge inside the wind screen (see Fig. 5). It is specially designed to minimise its effect on the frequency and directional characteristics of the assembly.
Chemical resistant
All essential components are made of stainless steel to withstand tough environments.
Support and Protection
The windscreen is supported by three stainless steel rods that also protrude as rubber-capped spikes, which prevent birds from perching on the microphone. Each of the bird spikes is capped with soft rubber to make them easier to see and to help prevent eye injuries (see Fig. 5).
Long Lasting
The unit provides excellent long-term mechanical stability. Should the frame become bent or the foam worn-out, replacements are available.
Easy Acoustic Calibration
Many all-weather microphone systems provide durability at the expense of microphone accessibility, which makes acoustical calibration difficult. With Type 4198 and UA-1404, the windscreen and rain cover assembly can easily be removed, thus exposing the microphone for easy acoustical calibration (see Fig. 5).
Unattended Outdoor Monitoring
All of the features of Type 4198 and UA-1404 combine to create an assembly that can safely be installed for semi-permanent outdoor sound measurement. The assembly will maintain consistent performance even when left unattended in bad...
