DriveCore: DriveCore Technology
seamlessly integrates the amplifier drive stage into the power output stage
fusing everything into a chip the size of a dime. The foundational DriveCore
circuitry is based on breakthroughs by Crown's own Gerald Stanley with five
patents applying to the advanced feedback, modulation, and output stage
technologies. DriveCore's front-end drive circuits leverage the inherent
efficiency of Class D output stages while also maintaining superb sonic
characteristics. The end result is an ultra-efficient one-piece audio amplifier
circuit that exhibits the exemplary audio quality of a highly evolved Class AB

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. 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
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.
Inputs: The XLS Series amplifiers provide XLR (one per channel), 1/4"
(one per channel), and RCA (one per channel) for flexible connectivity. The
1/4" inputs can be used as a loop-thru to
distribute signal to additional amplifiers.
Outputs: The XLS Series amps feature two 4-Pole Speakon
output connectors that will accept 2-pole or 4-pole Speakon connectors. The
Channel 1 Speakon
connector is wired for both channels so it can be used for bridged-mono wiring
or for stereo wiring of two speakers to a single Speakon connector. There is
also one pair of back-panel binding posts per channel that will accept banana
plugs or bare wire.
Note: The amplifier's two channel outputs are equipped with independent
Gain (Level) control.
LCD Screen: The amplifier's front-panel, back-lit LCD screen allows
for crossover configuration, amplifier mode configuration, and limiter
Flow-Through & Forced-Air Cooling: The XLS Series amplifiers employ
flow-through, front-to-back ventilation and internal heat sinks with forced-air
cooling for rapid, uniform heat dissipation.
Protection Circuitry: XLS Series amplifiers provide extensive
protection and diagnostic capabilities, including output current limiting, DC
protection, circuit breaker, and thermal protection.
LED Indicators: The power amplifier features ten LEDs (five for each
output channel) to indicate status of amplifier.
- Single Presence: Two green LED's, one for each channel,
illuminate when the channel input signal exceeds -40dBu.
- -10: Green LED flashes when output signal level exceeds -10dB
- -20: Green LED flashes when output signal level exceeds -20dB
- Clip: Two red LED's, one for each channel, illuminate when the
channel's output is being overdriven.
- Thermal: Two red LED's, one for each channel, illuminate when
thermal compression begins.
