  • ANALOG & DIGITAL INPUTS – With digital audio transport via HARMAN’s proprietary BLU-Link, plus balanced analog inputs, DCi gives you a tremendous audio advantage – at a much lower cost. The priority input router allows you to specify a primary input, and if audio is lost the amp automatically switches to the other input.
  • NETWORK MONITORING & CONTROL – Better monitoring, control and audio manipulation with the HiQnet™ protocol that’s over standard TCP/IP. Remotely see how all networked DCi amplifiers are performing and control them as needed. In addition, this allows Audio Architect software and the Powered by Crown app to work with DCi amplifiers.
  • PROGRAMMABLE GENERAL PURPOSE INPUT/OUTPUT PORTS – GPIO ports can be configured in many different ways, such as volume controls, recall presets, or to report errors to a master computer.
  • DIGITAL SIGNAL PROCESSING – DSP capabilities include the following:
    • LevelMAX Limiters
    • Input/Output EQ
    • Crossover
    • Delay
    • Matrix Mixer
    • Speaker Line Monitoring
