About the Crown XLS 2502
Give your speakers the power they deserve
Give your speakers the power they deserve
Crown's XLS 2502 2-channel power amplifier can put out 440 watts per channel at 8 ohms, 775 watts at 4 ohms, 1200 at 2 ohms, and up to 2400 watts when bridged — enough to cleanly power a wide variety of loudspeakers. This highly efficient Class D amp employs internal heat sinks with forced-air cooling to keep the internal temperature under control, and an automated rear fan that kicks in when you're pushing the amp hard.
Controls you'll use
The amp's front panel offers independent gain control knobs, LED level/clip indicators, an on/off switch, LCD screen, and three menu control buttons. The LCD screen lets you configure the amp mode, set the limiter, and adjust the crossover configuration with the push of a few buttons. The rear of the XLS 2502 is a veritable treasure trove of connections — balanced XLR, 1/4", and RCA inputs, so you can get creative with your audio sources. The 1/4" line-level outputs let you add more amps to the mix. You'll find binding posts and Neutrik Speakon® outputs for the speakers, plus a built-in circuit breaker to protect against overload.
Technology under the hood
Crown's patented DriveCore technology allows their XLS amps to maintain high efficiency even when they're being powered by untrustworthy AC current. Unstable electrical loads typically introduce heavy noise into most Class D amps, but the DriveCore circuit keeps the distortion to practically zero. So even if you've got to plug in near a lighting rig or other backline gear, XLS amps wipe away interference so your signal always remains clean.
Built-in PureBand™ Crossover System
Are you working with subwoofers, multiple speakers, or floor monitors? You can maximize the XLS 2502's energy by employing its integrated PureBand Crossover System to tailor the sound to fit each of your speakers. It lets you choose the crossover point just about anywhere between 50 and 3000 Hz, and gives you steep 24 dB/octave slopes for seamless transitions between different drivers. Your choice of three different crossover modes, high-pass, low-pass, and bandpass, let you configure your system to nearly any situation or speaker setup, whether you need big-time bass or just need to hear the vocals clearly above the thrash and thunder. And the settings can all be adjusted right from the amp's front panel.
Peakx Limiters keep you out of trouble
Crown's Peakx Limiters give you the confidence to push your system hard without shutting down the entire production. You'll be able to push the volume up safely without fear of sonic distortion littering the audience's ears or wrecking your speakers. Crown put independent Peakx Limiters on every channel, and they're defeatable right from the front panel.

Overview: Crown's new XLS DriveCore 2 series of power amplifiers feature an upgraded look with a larger display. Like their predecessors, the new XLS amps are equipped with Crown's patented DriveCore technology. The XLS 2502 can drive your speakers with 2400 watts (at 4Ω bridged) of clean power with very low distortion.
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 design.
Power Rating: The Crown XLS 2502 can power 8Ω, 4Ω, or 2Ω loads, and can be bridged for 8Ω or 4Ω mono operation. The maximum average power in watts at 0.5% THD, 1 kHz is as follows:
|Impedance Load||Dual Mode (stereo)||Bridged Mode (mono)|
|2 ohm||1,200 watts||N/A|
|4 ohm||775 watts||2,400 watts|
|8 ohm||440 watts||1,550 watts|
PureBand Crossover System: The PureBand Crossover System in the XLS DriveCore 2 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 30Hz and 3kHz on 1/12th octave centers. The use of 24dB/octave Linkwitz-Riley filters provides steep slopes for a seamless transition between high and low drivers. You can choose from three filter types: Low Pass, High Pass, and Band Pass.
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 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.
Inputs: The XLS DriveCore 2 Series amplifiers provide one balanced XLR, one 1/4", and one RCA connector 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 DriveCore 2 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.Level Controls: The amplifier's two channel outputs are equipped with independent Gain (Level) control. These front panel rotary controls let you raise or lower the gain as you view the LED indicators to provide an optimal signal to the amp.
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 below clip.
- -20: Green LED flashes when output signal level exceeds -20dB below clip.
- 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.
Main Menu: The amplifier's back-lit LCD screen allow you to navigate through the main menu and make adjustments to the amplifier right from the front panel:
- Amp Mode: Allows you to select one of three amplifier
- Stereo: Channels 1 and 2 function as independent amplifiers
- Bridge: The output is set into a bridge configuration
- Input-Y: Drives the two channels with the same input signal
- Crossover: Lets you select the filter type and frequency for each amplifier output channel. In Stereo or Input-Y mode, you will first be prompted to select which amp channel to set up. Once the channel has been selected, or if you are in Bridge Mode, you can choose from the following: Low Pass, Band Pass, or High Pass
- Input Sensitivity: Input Sensitivity enables you to set
the input sensitivity for the optimal system performance. You can choose
- .775V - High: For sources with inherently low output levels, select this mode to drive the amplifier to full power. Typically, sources that use the RCA connections require the High setting.
- 1.4V - Normal: For all other audio sources, the input sensitivity should be set to normal
- System Menu: The System Menu lets you select the
- Display Sleep: Sets the display to go into sleep mode after a predetermined idle time: 30 sec, 1 min, 2 min, 5 min, or sleep mode off.
- Lighting: Lets you toggle on or off the blue panel lights and the green signal level indicators. The thermal and clip indicators cannot be turned off.
- Security: Allows you to lock the menu buttons so that the settings cannot be disturbed once they have been set up.
- System Information: Lets you access additional information, such as the model number, internal temperatures and voltages, firmware version, etc.
- Factory Reset: Lets you reset the amplifier to the factory default settings. This allows you to start your setup from the beginning, if you desire.
Flow-Through & Forced-Air Cooling: The XLS DriveCore 2 Series amplifiers employ flow-through, front-to-back ventilation and internal heat sinks with forced-air cooling for rapid, uniform heat dissipation.
Aux Connector: A 3-pin Aux connector on the rear panel lets you remotely trigger sleep mode through a contact closure on pins 1 and 2. An amp status signal is available on pin 3.
