Crown's XLS 2500 is a premiere, portable power amplifier 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. This high-performance power amp provides enormous power and flexibility thanks to the integrated DriveCore Technology, PureBand Crossover System and Peakx limiters. Weighing less than 11 pounds, the Crown XLS2500 power amp is much easier to set up and move from show to show.

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 the Crown XLS2500 power amp won't compromised your performance by fluctuating generator power, or overload from 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

The advanced power supply in the Crown XLS2500 power amp 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 Crown XLS line weigh 10 pounds or less with no compromise in performance. This makes the Crown XLS2500 power amp and others in the XLS Series the benchmark for high-performance, lightweight portability.

PureBand Crossover System
The PureBand Crossover System in the Crown 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.

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 sound pressure level (SPL) with 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.

Yeah baby!!!

By Ivory James

from Phoenix, AZ

Comments about Crown XLS2500 DriveCore Series Power Amp:

One word: Awesome. Set up right next to our PV 2600 and sounded virtually identical, just a touch less powerful (which it should be since the PV is a 900W@4 ohm amp vs 775.) However, this amp does 2 Ohms and weighs 11 pounds! The PV weighs close to 50! I've used it for a few shows already in mid-sized bars and small clubs and have tons of headroom on my mixer with the amps only 1/2 way up (or a little more in some cases.) I'm using JBL JRX125 quasi 3 way 4 Ohm speakers, which are daisy chained (resulting in 2ohms) into one channel, and running Yamaha 15" monitors through the other. 1200 watts at 2 Ohms! Awesome. I'm a little nervous about the digital controls and crossovers, but my drummer, who is also an electronics engineer, says don't worry about it. So I won't. Very good sounding, sturdy and powerful product. I gig 2 or 3 nights a week, so even if this thing dies after the 3 year warranty, I will be far ahead. Oh yeah, did I mention it weighs 11 pounds! Two thumbs up.

This is the Amp!

By Hazy Schumacher

from Denver Colorado

Comments about Crown XLS2500 DriveCore Series Power Amp:

I run all my highs with this baby. It puts out enough power to run 4 Harbinger HX152 cabinets. Thats a total of 8 15" woofers and 4 -1 3/4" compression drivers. The sound is amazingly clean and responsive. I cant believe the capabilities when it comes to inputs and links. I had someone show up with a laptop that wanted to record and I had no more outs on the mixer, well the amps have outputs so I just hooked up to one of them. AWESOME!!!!!

Great amp!

By Paul Zutter

from Madison, AL

Comments about Crown XLS2500 DriveCore Series Power Amp:

This is a great amp. I really like it's light weight and built in crossovers. The availability to set up one channel as hi pass and the other as low pass from the front control panel is a great feature. The sound is crystal clear while producing chest thumping lows. I would by another when needed.

A light power amp with clear sound!

By Carleton Norris

from Birch Run, MI

Comments about Crown XLS2500 DriveCore Series Power Amp:

Over the past three years our band has been using Yamaha power amps to run our main and monitor systems. As we get older and move the equipment, it feels like it is getting heaver every day. When we were shopping at our local Guitar Center, the sales person told us about the Crown XLS series power amps that are 11 lbs in weight. So we decided to give an XLS2500 a try. The crown XLS power amp had a bright. clear and natural sound. We liked the sound quality to the point where we replaced both power amps with the new XLS, that save us a total of 30 lbs in our rack. The Crown units are not as deep, so we also have a less cable congested in the back rack area. The extra features includes the PureBand? Crossover System and the Peakx? limiters, we are running the amps in stereo just using the limiters. The controls are at easy access in the front cover. In closing I have to say that the Crown XLS2500 power amps are nice quality, bright clear sound, with a terrific price.
