The XLS Series of power amplifiers from Crown define the standard for live sound systems with unmatched performance, technology and affordability. This high-performance line consists of four models, each providing enormous power and flexibility thanks to the integrated PureBand™ Crossover System and Peakx™ Limiters.

Class D amplifiers are notable for extraordinarily high efficiency and being well suited for driving difficult reactive loads such as subwoofers. However, their performance can suffer impaired performance on marginal and unstable AC line supplies.  To overcome this obstacle, Crown engineers developed DriveCore™ Technology – a proprietary hybrid analog-digital integrated circuit (IC) developed with Texas Instruments that drives the "front end" of the Class D output stage. Over 60 years of Crown's design knowledge and experience went into the development of this technology resulting in truly remarkable benefits.

DriveCore™ Technology provides an extremely wide-tolerance with regards to sagging or "dirty" AC line conditions providing consistent performance without affecting audio quality. This means that your performance will not be compromised by fluctuating generator power or overloading by lighting rigs, backline gear, etc.

In addition, DriveCore™ Technology's patented feedback and PWM modulation circuits enable fast recovery on peak transients, accurate reproduction of low-level detail, and precise tracking of low-frequencies at high power levels for maximum subwoofer output.

And weighing in at only 11 lbs or less, they provide the ultimate in lightweight portability. Generating chest-thumping lows and crystal clear highs, the four models in the series – the XLS 1000, XLS 1500, XLS 2000, and XLS 2500 – are engineered to meet any demanding audio requirements – reliably and within budget.  With over five decades of experience designing and building rock-solid products, Crown is the standard in amplifier technology. So check out the Crown XLS Series. They are a powerful argument for performance, flexibility and value.
