    Crown’s XLS Series amplifiers define the standard for portable PA systems 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. The integrated crossovers and switch-mode power supply produce superior sound, and Peakx™ limiters protect your speakers. Weighing less than 12 pounds, compared to 40 pounds for its competitors, it’s much easier to set up and move from show to show. Simply put, the XLS is most reliable, versatile, efficient amp available today.

    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:

    1. 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.
    2. 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.
    3. 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.
    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 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.
