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 30 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.

    Product Research


    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 modes:
      • 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 from:
      • .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 following:
      • 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.

    5 questions already asked

    Is he lying about short circuit protection ?
    [ johnnny  Dec 16, 2022 ]
    1 answer
    This power amp does have a lot of features including short circuit protection however speaking with one of our pro audio specialists would be a great way to dive into more details about it. Give us a call at800.555.9369 and they can get you set up!
    [ Arielle  Dec 16, 2022 ]  Staff
    Can this amp be connected to a home reciver?
    [ Miguel  Jan 06, 2021 ]
    9 answers
    The simple answer is YES, it can be connected using standard RCA connections. I have had the amp for about a year and I'm really happy with it. I have it connected to my home receiver (an Outlaw RR2160) using the "PRE-OUT" connection. It is being used to drive a pair of Polk Audio RTi A9 speakers and it provides all the power those speakers need to sound their best.
    [ JEFF  Jan 07, 2021 ]
    It can be connected but this is not a Hi Fi amplifier. Is a good sounding equipment but is not quiet , you will be hearing "hiss" . This is an amplifier to play music or voice outdoors or some commercial applications.
    [ Luis  Jan 07, 2021 ]
    Most Receivers have a line level output or a tape loop. If your Receiver has such an audio output, simple connect it to the Amplifier`s input. Be careful keep the volume low at first.
    [ Anthony Castrovinci  Jan 06, 2021 ]
    Yes you can but your home receiver would need stereo RCA pre-out
    [ HERBERT  Jan 06, 2021 ]
    Your home receiver needs a PRE OUT connector, to connect to this amplifier.
    [ JC  Jan 06, 2021 ]
    This is a power amplifier. If your home receiver has separate preamplifier outputs, then you connect them into this amp, then connect this amp to your speakers. They are great amps, especially for driving sub woofers! Be careful as they are VERY powerful!!
    [ GREG  Jan 06, 2021 ]
    Yes absolutely. I have it connected to a Yamaha RX-A2000 via sub out to drive my Eminence NSW6021-6. Its enough to shake my whole house and drive my wife mad resulting me in sleeping on the couch :)
    [ A  Jan 06, 2021 ]
    Yes if your home receiver has a pre-out then you can use it to replace your receiver's left/right main channel output.
    [ AARON  Jan 06, 2021 ]
    You should be able to connect to your pe-out, rca's or xlr's on your receiver if your receiver is equipped with these connection options. some of the lower model receivers do not have.
    [ PETE  Jan 06, 2021 ]
    Is the scratch and dent item visibly noticeable?
    [ Mike  Aug 18, 2020 ]
    2 answers
    I never found the scratch or the dent
    [ FRANK H  Aug 19, 2020 ]
    not on my unit.
    [ Michael  Aug 19, 2020 ]
    is it work without any setting on factory setting?
    [ dr anil  Oct 02, 2019 ]
    1 answer
    Thank you for your question. If I have read your question correctly, it will work out of the box, however, there are settings that will help you fine tune your sound.
    [ Jess  Oct 14, 2019 ]  Staff
    Is this a good amp for use in home theater , front left and right ?
    [ Piggy  Apr 06, 2019 ]
    5 answers
    I have researched this amp and the value is great. I have listened with it for less than three hours. I will use it with my two front channels in my system and it is very neutral sounding. It has the power if I want to use it with outdoor venue speakers. So it is versital. But I can adjust the sound of my system anyway I want with my equalizer, programs and hardware. I will also get a class A, B amp... Emotiva. I am just starting out with the amps and can resale or return them if I want. Eventually, I will be satisfied with my system. I hope this helps you.
    [ KIRK  Apr 20, 2019 ]
    While this amp will do what you are asking, it is incredibly powerful and typically used to power 3 to 4 18 inch subwoofers in concert settings. I use it to power 2 custom made 15 inch subs I have. I like to feel the earth/floor move when I listen to my music and this amp does that!!
    [ GREG  Apr 16, 2019 ]
    That's what is mine for . It works well , quiet and stays cool. I am only running mine with 8 ohm speakers so I'm only using the minimal amount of power the amp should provide. If you are using 4 ohm speakers you will should get a lot more power from the amp. I feel it may be a little over rated as far as power output but like I said, I'm only running a 8 ohm load. Nice little amp so far. Had for nearly a year.
    [ Elizabeth  Apr 16, 2019 ]
    I forgot to mention that I am only running mine with a 8 ohm load so it would definitely make more power if you have 4 ohm speakers. Hope this helps.
    [ Elizabeth  Apr 12, 2019 ]
    That's exactly what I'm using it for at the moment. It does a decent job but I feel that the power rating is a little exaggerated (imo) but I have no way of testing this. It does have a lot of features that make it nice for other applications as well with the built in crossovers . I will probably use mine to power another zone in the future when or if I upgrade.
