48 channel beamforming microphone array for various measurement scenarios This star array is a 48 channel measurement system designed for outdoor applications. The lightweight aluminum array body is designed as slim as possible to ensure easy handling and accurate microphone positioning. The included high-end tripod allows set-up in almost any measurement environment imaginable. This array is foldable and connects to the data recorder. 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 23 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).
