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 10 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 XLS1000, XLS1500, XLS2000, and XLS2500 – are engineered to meet any demanding audio requirements – reliably and within budget. Every XLS Series amplifier is backed by Crown's unequaled Three-Year, No-Fault, Fully Transferable Warranty that covers everything. 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! 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 60Hz transformer-based power supplies. All four models in the line weigh 10 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 50Hz and 3kHz 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. And with four crossover modes to choose from providing the ultimate in flexibility, all of your system needs are covered: - Crossover Mode (CH1=LPF, CH2=HPF) – When chosen, this mode enables a LowPass Filter on Channel 1 and a HighPass Filter on Channel 2 at the frequency chosen.
- LowPass Mode (CH1=LPF, CH2=LPF) – When chosen, this mode enables a LowPass Filter on both Channel 1 and Channel 1 at the frequency chosen.
- HighPass Mode (CH1=HPF, CH2=HPF) – When chosen, this mode enables a HighPass Filter on both Channel 1 and Channel 2 at the frequency chosen.
- Bridge Mode (LPF or HPF) – When the amplifier is put into Bridge-Mono, you are still able to use the crossover system and employ either a LowPass Filter or HighPass Filter at the frequency chosen.
All of the PureBand™ Crossover System settings can be fully configured quickly and easily from the front panel using the intuitive LCD interface. Peakx™ limiters Peakx™ limiters provide the ultimate in performance and protection for your entire system. This advanced algorithm was specifically developed and tuned to work with this amplifier and power-supply to achieve higher SPL will less audible artifacts. This means less distortion, less shutdowns, and maximum safe power delivered to your speakers. The Peakx™ limiters can be easily turned on or off by channel right from the front panel eliminating the need to be digging around in the back of the dark rack.
