Crown XLS 1000
2-Channel 350W Power Amplifier Rated @ 4 Ohms / Channel


Sorry this product is currently out of stock.

The Crown XLS 1000 is a 2-channel power amplifier rated at 350W @ 4 ohms per channel. 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. This amplifier weighs less than 12 pounds, and is much easeir to set up from show to show, compared to 40 pounds for various competitors, it's much easier to set up and move from show to show.

XLS Series with Integrated DriveCore™ Technology
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. They only weigh 10 lbs or less, and thus provide excellent lightweight portability.

All four models in the series – the XLS1000, XLS1500, XLS2000, and XLS2500 – generate chest-thumping lows and crystal-clear highs to meet demanding audio requirements, reliably and within budget.

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 came up with 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. DriveCore™ Technology provides a 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, making the XLS Series a 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, your system needs are covered:

  • 1. Crossover Mode (CH1= LPF, CH2= HPF) –When chosen, this mode enables a Low Pass Filter on Channel 1 and a High Pass Filter on Channel 2 at the frequency chosen.
  • 2. Low Pass Mode (CH1= LPF, CH2=LPF) –When chosen, this mode enables a Low Pass Filter on both Channel 1 and Channel 1 at the frequency chosen.
  • 3. High Pass Mode (CH1= HPF, CH2=HPF) –When chosen, this mode enables a High Pass Filter on both Channel 1 and Channel 2 at the frequency chosen.
  • 4. 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 Low Pass Filter or High Pass 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 designed to work with this amplifier and power-supply to achieve higher 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.
