Harman’s Crown Audio has expanded its DriveCore Install (DCi) Series amplifier range with the introduction of the DCi Network Display 8|600ND and 4|1250ND power amplifiers, providing both front-panel status displays and AVB (Audio Video Bridging) connectivity.

According to Crown Audio, the new 8- and 4-channel DCi Network Display amplifiers will be the first professional audio amplifier to be certified by the AVnu Alliance. DCi Network Display amplifiers will deliver reliable audio performance and networked operation in AVB-based audio/video systems.

“Since their recent introduction our Crown DCi Series amplifiers have set a new standard for installed sound, and our new DCI Network Display amplifiers build upon this industry-leading performance by offering certifiable compatibility with AVB-based installations, along with easy setup and operation and unshakable reliability. Combining DriveCore technology with AVB represents another first from Crown as we continue to lead the way for professional amplifier innovation for the most demanding large-scale environments,” said Daniel Saenz, business segment manager, Crown Audio.

Both DCi Network Display amplifiers include a front-panel display and LED indicators that provide at-a-glance indication of key parameters. A large multifunction knob and push buttons enable instant access to control functions.

The amplifiers are compatible with Harman’s HiQnet Audio Architect system setup and control software and utilize TCP/IP-based protocol in HiQnet for network monitoring and control.

The 8-channel DCi 8|600ND delivers 600 watts into 8 ohms (300, 600 and 300 watts into 16, 4 and 2 ohms) and the 4-channel DCi 4|1250ND provides 1,250 watts into 8, 4 or 2 ohms (625 watts into 16 ohms). Both amplifiers offer direct drive “constant voltage” capabilities for 70 volts rms and 100 volts rms amplification without the need for a step-up transformer, yielding higher audio quality in distributed audio applications with power outputs of 1250 watts and 600 watts, respectively.

Like all Crown DCi Series amplifiers, the DCi 8|600ND and DCi 4|1250ND utilize HARMAN’s proprietary DriveCore amplifier IC chip for powerful, highly efficient operation from a compact form factor measuring 2 RU. The DriveCore chip combines the amplifier driver stage into the power output stage along with additional audio-signal functions, yet is about the size of a postage stamp. The DriveCore-based Class D, next-generation PWM design reduces size and power consumption and yields much more energy-efficient operation.

Both amplifiers provide a host of networking and control features to ensure reliable operation, including continuous load monitoring, comprehensive error reporting, pilot tone monitoring and programmable general purpose input/output (GPIO) ports. The DCi 8|600ND and DCi 4|1250ND offer extensive DSP capabilities such as LevelMAX limiters for the inputs and outputs, with thermal limiting, input and output delay, input and output EQ, built-in crossovers and a built-in signal generator.

The amplifiers incorporate an exclusive Power Factor Corrected (PFC) universal power supply that is designed to deliver maximum power in any country and their universal AC input accepts voltages from 100 – 240 volts AC, 50/60 Hz (+/-10 percent). A newly-designed cooling system focuses the airflow on where it’s needed most, yielding maximum efficiency even under demanding operational conditions.

Crown DCi Series amplifiers carry a 3-year, no-fault fully transferrable warranty.
