Push your passive PA with a serious power amp. Pushing a max of 2400 watts of Class D power, the Crown XLS2500 offers variable crossovers and Peakx limiting.

Can an 11-pound power amp drive an entire venue's PA system? The Crown XLS 2500 can. As the most powerful unit in the XLS series, the XLS 2500 packs a whopping 2400 watts into a 2U rack space design that's astonishingly lightweight, yet robust enough to push multiple mains, monitors, subwoofers, or all of the above. Thanks to its lightweight construction, integrated DriveCore Technology, PureBand Crossover System, Peakx limiters, switch-mode power supply, and more, the XLS 2500 is able to provide the headroom you need to drive more passive speakers, without distortion.

DriveCore Technology for a Better Class D Amp

When you have an amp driven by DriveCore Technology, there's no way that faulty power sources can affect your performance. Developed by Crown in collaboration with Texas Instruments, DriveCore Technology -- a proprietary hybrid analog-digital integrated circuit (IC) -- drives the front end of the Class D output stage, allowing the XLS 2500 to overcome setbacks caused by sagging or "dirty" AC lines, such as those that may be powering other equipment at the same time. DriveCore ensures that even if you plug the XLS 2500 into an unreliable wall outlet or if there's simply too much going on at the same time, you won't hear any difference in sound quality.

Complete Crossover Control

With the XLS 2500's PureBand Crossover System, you can vary the crossover frequency at any point between 50 Hz and 3 kHz on read more 1/12 octave centers, which means you get dedicated control over what frequencies you're sending to each channel. Four crossover modes -- Crossover, LowPass, HighPass, and Bridge -- let you engage either a low-pass filter or high-pass filter at your chosen frequency. You can conveniently configure all PureBand Crossover System settings from the front-panel LCD interface.

Built-In Speaker Protection

Thanks to Peakx limiters, Crown's XLS 2500 is able to achieve higher sound pressure levels (SPL) with fewer unwanted artifacts, providing the greatest amount of safe power to your speakers with very little distortion and fewer shutdowns. As with the crossover settings, Peakx limiters can be turned on or off from the XLS 2500's front panel.

A Switched-Mode Power Supply for Lightweight Portability

The XLS 2500's advanced switched-mode power supply is what makes the amp so light. Optimized for maximum power transfer from the AC line through the Class D output stage to the loudspeakers, the power supply sheds the pounds in exchange for ease of use and portability. When you've got a van full of gear to transport and set up at your next gig, having an 11-pound power amp like the Crown XLS 2500 can make things so much easier. With this lightweight power amplifier, you will gladly take your show on the road.

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.

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.

I would like to let anyone considering this amp for home use to go for it. I have been using the xls2500 for my home stereo and it rocks I am using it with a pair of cerwin vega xls-215 and it really made everything sound more clear and pronouced. It is hooked up to my old jvc 884 receiver. I play it loud and it still runs cool and the never comes on. The only thing is a very low hum when at zero volume but goes away the minute I turn up the volume even at low settings. I was skeptical when I ordered it but I am very happy that I tried it. I will be ordering a second one soon with another pair of cerwin vega xls-215 speakers.
