PROJECT MANAGEMENT WITH QUESTRA®

With the expansion cards (Ethernet or Ethernet + Dante), IPA DSP installation amplifiers are the hardware backbone behind a QUESTRA installation. In conjunction with LD Systems' QUESTRA® software, the interface card provides flexible and effective configuration and control of fixed audio installations of various sizes - whether in hotels, restaurants, shopping centres, sports facilities, office environments and more. Furthermore, various supported network protocols (TCP, UDP, OSC etc.) enable external audio, lighting, video and control solutions to be seamlessly integrated.
