Crown XLS2500 Power Amp

The XLS 2500 is a leader in portable amps, with DriveCore Technology, PureBand Crossover System, and Peakx limiters.


Crown's XLS 2500 power amplifier is a premiere portable PA system 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 12 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.
