Meet the new XLS DriveCore™ 2 Series

The next generation of XLS got a makeover with a sleek new look, a LCD display that is three times larger, and more DSP with higher capabilities. Like its predecessor, the new XLS is ultra-efficient with Crown’s patented DriveCore technology and can drive 2400W at 4Ω bridged with tons of headroom guaranteeing a clean, undistorted signal straight to your speakers. The XLS DriveCore 2 assures that you will be heard as you deliver a powerful, pure sound experience for any venue.

• Class D amp with Crown's ultra-efficient DriveCore technology weighs less than 11 lb 
• Higher DSP capabilities: More control; has band pass filter per channel 
• Increased lighting functionality; turn off all LED indicators except clip and thermal to reduce distraction in dark venues
• Selectable input sensitivity; 1.4Vrms and .775Vrms options so that amp can be driven at full power
• Set sleep mode after specified time without having to press a button
• Security setting disables menu buttons; menu locked/unlocked by entering combination
• System reset allows factory settings to be restored
• Remote power trigger
• Peakx™ Limiters provide maximum output while protecting your speakers
• XLR, 1/4", RCA inputs provide flexibility
• Integrated PureBand™ Crossover System for better performance and control
• Efficient forced-air fans prevent excessive thermal buildup 

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:

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.

Peak_x™ limiters 

Peak_x™ 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 Peak_x™ 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.

NEWS - April 2015

FRANKFURT, Germany — HARMAN’s Crown Audio today announced the introduction of the XLS DriveCore™ 2 Series two-channel power amplifiers, offering a host of upgraded features including more flexible DSP band pass filtering, selectable input sensitivity, remote power trigger operation and sleek new styling. Four new XLS DriveCore 2 models are available including the XLS 2502, XLS 2002, XLS 1502 and XLS 1002, with power ratings from 350 to 775 watts per channel at 4 ohms and 1100 to 2400 watts at 4 ohms bridged. Setting new performance and value benchmarks at their respective price points, Crown’s XLS DriveCore 2 Series amplifiers feature HARMAN’s exclusive DriveCore amplifier circuitry that combines high power output with exceptional energy efficiency, all under 11 lbs (5 kg).

“The XLS Series has been a true industry workhorse and with the introduction of the XLS DriveCore 2 models, the amplifiers are even better suited for a wider range of live, portable PA and installed sound applications,” said Craig Lambrecht, Business Segment Manager, Crown Audio. Crown XLS DriveCore 2 amplifiers now offer a bandpass filter on each channel in addition to the previous low and high pass filters, enabling more precise DSP crossover tuning, loudspeaker matching and system EQ capability. All models allow the front-panel LED indicators (except the clip and thermal indicators) to be turned off if desired, reducing distraction in dark venues. All the amplifiers have selectable input sensitivity of either 1.4 Vrms or .775 Vrms, facilitating their use in a wider variety of applications and enabling the amplifiers to be driven at full power.

XLS DriveCore 2 amplifiers now offer a remote power trigger function, to turn the amp on and off from a distance. The amplifiers also feature a display sleep mode that turns the display lighting off after a specified time. All models provide a security setting that disables the front-panel menu buttons; the menu is locked and unlocked by entering a simple button combination. In addition, a system reset function enables all factory settings to be restored. Power ratings of the XLS DriveCore 2 models (per channel into 4 ohms) are as follows: XLS 2502, 775W; XLS 2002, 650W; XLS 1502, 525W; XLS 1002, 350W. All incorporate Crown’s proprietary DriveCore Class D amplifier design, which is the size of a postage stamp yet combines the amplifier driver stage into the power output stage along with additional audio-signal functions to provide remarkably efficient, cool-running operation that conforms to HARMAN International’s GreenEdge™ environmental initiative. All the amps are just 2U rack spaces high.

Crown XLS DriveCore 2 amplifiers can power 8- 4- or 2-ohm loads and can be bridged for 8- or 4-ohm mono operation. Additional features include Peakx™ limiters that deliver maximum output while protecting the speakers; balanced XLR, 1/4-inch and RCA inputs; touchproof binding post and Speakon® outputs and more.
