Harman's Crown Expands DCi Network Series Amplifier Lineup with Two New ModelsHarman's Crown Audio today announced it has added two models to the DriveCore Install (DCi) Network Series amplifier lineup with the introduction of its DCi 4|2400N, DCi 2|2400N, and DCi 2|1250N power amplifiers. The new amplifiers incorporate Harman's exclusive DriveCore technology to deliver high power output from a compact, energy-efficient form factor, and offer extensive networked system control capabilities. "The high-power amplifiers fill out our DCi Network Series amplifier line with channel configurations and power ratings that were unavailable before, including two-channel and four-channel models with 2400W per channel," said 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 installedsound 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 1,900W into 8ohms, 2,400W into 4ohms, and 2,100W into 2ohms. All power outputs are minimum guaranteed power ratings -- Crown DCi amplifiers are guaranteed to deliver at least their rated power over a longer period of time than any competing amplifier. In addition, the ampifiers offer direct drive "constant voltage" capabilities for 70Vrms and 100Vrms 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 comprehensive 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 Cat5e 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 a lighter-weight, installation-friendly 2RU form factor. The ultra-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 - 240VAC, 50/60Hz (+/- 10%). The amplifiers' cooling system focuses the airflow on where it's needed most, minimizing heat and noise. Crown DCi Network Series amplifiers are built for the most demanding conditions of professional use and carry a three-year, no-fault fully transferrable warranty.
