48 channel system for various measurement scenarios

Depending on a signal’s spectral composition, the recommended measurement distance varies between seven and 500 meters. Longer ranges are possible with consideration of wind and other influences. The wiring of the microphones is enclosed in and protected by the array-body, guaranteeing the best possible acoustic transparency to measure accurate sound levels.The array is foldable and fits in a mid-size station wagon.

This array design represents a compromise between portability, map dynamic, and spatial resolution. Additionally, the array pattern is easy to identify and indicates wrong focus settings while still pointing to the source’s position. As this microphone array has 20 dB backfield suppression by design, it can be used in most outdoor applications.

The built-in studio microphones have an extremely linear frequency response. All are carefully hand-selected and calibrated to ensure stable sound pressure levels (+/- 0.5 dB). To allow long distances, the array is connected to the data recorder via two differential SymBus microphone connector cables (max. 20 m). The array comes with an integrated fixed focus Ethernet camera, delivered in different sensor sizes, resolutions and frame rates. Array and tripod are supplied in transport bags.
