Crown's XLS Series amplifiers define the standard for portable PA systems with unmatched performance, technology and affordability. Its advantageous flexibility includes multiple inputs so you can plug in anything and play anywhere, along with several system setup configurations. The integrated crossovers and switch-mode power supply produce superior sound, and Peakx™ limiters protect your speakers. Weighing less than 11 pounds, compared to 40 pounds for its competitors, it's much easier to set up and move from show to show. Simply put, the XLS is most reliable, versatile, efficient amp available today.

XLS Series with Integrated DriveCore™ Technology
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 DriveCore™ Technology, PureBand™ Crossover System and Peakx™ limiters. And weighing in at only 11 lbs. or less, they provide the ultimate in lightweight portability.
Integrated DriveCore™ Technology
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.
Advanced Switched-Mode Power Supply
This advanced power supply is highly efficient and optimized for maximum power transfer from the AC line through the Class D output stage to the loudspeakers. A benefit to this is substantial weight reduction when compared to older 60 Hz transformer-based power supplies. All four models in the line weigh 11 pounds or less with no compromise in performance. This makes the XLS Series the benchmark for high performance lightweight portability.
PureBand™ Crossover System
The PureBand™ Crossover System in the XLS Series adds an enormous amount of flexibility and performance to any system. With this system, the crossover frequency is completely variable allowing the choice of any crossover point between 50 Hz and 3 kHz on 1/12 octave centers. The use of 4th order Linkwitz-Riley filters provides steep slopes for a seamless transition between high and low drivers. All of the PureBand™ Crossover System settings can be fully configured quickly and easily from the front panel using the intuitive LCD interface.
