Harman's Crown Now Shipping Its New DriveCore Install Series Power Amplifiers

Harman's Crown Audio is now shipping its new DriveCore Install (Dci) Series power amplifiers. Successor to the company's acclaimed CTs Series, the Dci Analog two, four, and eight channel amplifiers incorporate a host of improvements including Harman's exclusive DriveCore technology to set new industry standards in sound quality, flexibility and efficiency.

Twelve models in the Dci Series are available ranging from 300 W to 600 W of minimum guaranteed power into 4 and 8 ohms and 70Vrms and 100Vrms. The first number in the model is the amount of channels and the second number indicates the watts-per-channel power rating. All amplifiers are just 2U rack spaces high, to conserve valuable installation space.

"We designed the Dci Series to be the new world standard for amplifiers in installed sound applications," says Daniel Saenz, business segment manager of install sound at Crown. "In fact, the Dci Series could be nothing less, considering the CTs Series established itself as the benchmark power amplifier for fixed installations. The Dci Series lives up to the task and then some and audio professionals worldwide will appreciate its greatly improved performance, flexible features, high efficiency, and compact form factor."

At the heart of the Dci Series is Harman's proprietary DriveCore amplifier IC chip. 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. DriveCore and the Dci Series' leading-edge amplifier topologies dramatically reduce size and power consumption requirements and yield much more energy-efficient operation that conforms to Harman International's GreenEdge environmental initiative.

DriveCore technology dramatically reduces the footprint of the amplifier by replacing more than 500 parts from a typical amplifier design with one single IC. Smaller amplifier engines means more channels can be put into a 2 RU box with more capabilities.

Crown Dci Series amplifiers can be operated into 8-, 4- or 2-ohm loads and offer direct drive "constant voltage" capabilities for 70Vrms and 100Vrms amplification without the need for a step-up transformer, yielding higher audio quality and more power available at the speaker in distributed audio applications, the company says. The amplifiers incorporate an exclusive Power Factor Corrected (PFC) global power supply that is designed to deliver maximum power in any country and their universal AC input accepts voltages from 100 - 240 VAC, 50/60Hz (+/- 10%).

The Dci Series is Crown's greenest amplifier line ever, with a PFC power supply, a selectable powersave auto-standby mode where the amplifier will power down after 30 minutes of no input signal and consume less than 1 W. In addition to the amplifiers' balanced three-pin input connectors and two-pin terminal strip output connectors, a rear-panel AUX port enables the amplifiers to be integrated into control systems for remote on/off and amplifier fault monitoring.

Crown Dci Series amplifiers are built for the most demanding conditions of continuous professional use and carry a three-year, no-fault fully transferrable warranty.
