Additional models joining the Harman’s Crown Audio DriveCore Install (DCi) Network Series of power amplifiers—the new DCi 4|2400N, DCi 2|2400N—made their U.S. debut at the recent InfoComm 2015 show in Orlando.
“The high-power amplifiers fill out our DCi Network Series amplifier line with channel configurations and power ratings that were unavailable before, including 2-channel and 4-channel models with 2,400 watts per channel,” states Dan Saenz, business segment manager, Crown Audio. “With the introduction of the new amps, Crown is now able to offer a complete range of DCi Network amplifiers for every networked installed sound requirement, from smaller house of worship, restaurant, bar or retail installations to large-scale applications requiring multiple channels of high power.”
Both the DCi 4|2400N and DCi 2|2400N deliver 1,900 watts into 8 ohms, 2,400 watts into 4 ohms and 2,100 watts into 2 ohms. All power outputs are minimum guaranteed power ratings. In addition, the ampifiers offer direct drive “constant voltage” capabilities for 70-volt rms and 100-volt rms amplification without the need for a step-up transformer, yielding higher audio quality and delivering their full rated power output in distributed audio applications.
Crown DCi Network Series amplifiers offer networked monitoring and control capabilities via their primary and secondary Ethernet ports. The ampifiers 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. All the amps offer BLU.ink compatibility with a low-latency, fault-tolerant digital audio bus, capable of routing 256 channels using standard Cat-5e cable over a distance of up to more than 300 feet between devices.
Like all Crown DCi Series amplifiers, the DCi 2|2400N and DCi 4|2400N incorporate HARMAN’s proprietary DriveCore amplifier chip for powerful, efficient operation from ab installation-friendly 2RU form factor. The compact Class D PWM DriveCore circuitry combines the amplifier driver stage into the power output stage along with additional audio signal functions.
Both amplifiers provide 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 amplifiers also offer DSP features including LevelMAX limiters for the inputs and outputs with thermal limiting, an input compressor, 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 and the most efficient operation in any country, and their universal AC input accepts voltages from 100 – 240 volts AC, 50/60 Hz (+/- 10 percent). The amplifiers’ cooling system focuses the airflow on where it’s needed most, minimizing heat and noise.
Crown DCi Network Series amplifiers carry a 3-year, no-fault fully transferrable warranty.
