48 channel beamforming microphone array for universal application This ring array is a 48 channel measurement system, which is the most popular and universal microphone array in the portfolio. It is especially used in the field of fault detection and quality control. The custom made carbon fiber array body ensures easy handling and precise array positioning due to its low weight. Furthermore, the geometry secures the greatest versatility and best possible local resolution of the acoustic map. This array can be operated with the data recorder. The lightweight array body is designed as slim as possible and is made of carbon fiber. This ensures easy handling and accurate microphone positioning. The wiring of the microphones is enclosed in and protected by the array body which guarantees the best possible acoustic transparency to measure accurate sound levels. The array design is optimized to provide the highest spatial resolution possible while providing a high depth of field to see all sources in one acoustic map independent of distance (within reason). The built-in studio microphones have an extremely linear frequency response. All mics 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 camera, which can be supplied as USB or Ethernet version, delivered in different sensor sizes, resolutions and frame rates. The included high-end Manfrotto tripod allows a set up in almost any measurement environment imaginable.
