The ideal choice for everything from meeting rooms to massive stadiums, the highly efficient DCi Series saves you time because it configures quickly and is simple to use. Plus, its lighter, space-saving design makes it easy to install wherever you want.
Designed, engineered and manufactured to the industry's highest quality standards for analog or network installations, the DCi Series provides system integrators with effortless, unmatched performance time after time.
Designed for minimum size and maximum power, DriveCore offers greater accuracy, reduced weight, and best-in-class signal-to-noise performance. The front-end drive circuits leverage the inherent efficiency of Class D output stages while also maintaining superb sonic characteristics. DriveCore means the patented feedback and PWM circuits provide fast recovery on peak transients, accurate reproduction of low-level detail and precise tracking of low frequencies at all power levels. Plus, fewer parts results in increased reliability - and the legendary performance you expect from Crown.
With extremely wide tolerance for AC line conditions, whether you're on a normal power grid or fluctuating back-up generator power for Life-Safety systems, DriveCore amps deliver sound that's never compromised. A proprietary hybrid analog-digital integrated circuit that's bolstered by multiple patents, DriveCore leads a new era of sustainable excellence. It also represents another historic milestone in our ongoing commitment to delivering audio products demanded by professionals - and that please audiences worldwide.
