DriveCore Technology – Crown’s proprietary DriveCore technology eliminates hundreds of components within each amplifier, reducing the variability of component values, increasing reliability, resulting in incredible audio fidelity from an efficient design.

Network Control and Monitoring – Through Harman’s HiQnet Audio Architect software, the CDi DriveCore can be controlled, configured, and monitored through standard TCP/IQ network.

DSP – On-board Digital Signal Processor in each amplifier allows for custom configuration

  • Input Router
  • Input Delay – Up to 1000ms
  • Input Parametric EQ – 8 band
  • Crossover
  • Output Parametric EQ – 8 band
  • Output Delay – Up to 100ms
  • LevelMAX™ Limiter

BLU link (BL models only) – Both receive and send channels over HARMAN’s 256 channel, fault-tolerant audio BUS, BLU link

Direct Drive 70/100Vrms Output – Each output channel is capable of provide either 70V or 100V for high impedance applications.

Front-Panel Interface – Completely configure the amplifier using an intuitive front-panel interface.

GPIO/AUX Port – Recall presets, mute channels, monitor faults, power on/off the amplifier, and more through a combined GPIO/AUX Port.
