Crown Audio XLS2502 Overview

The Crown XLS 2502 Stereo Power Amplifier offers 775W at 4 Ohm in a lightweight chassis using the company's ultra-efficient DriveCore Class D amplification platform. The amplifier includes built-in DSP with a dedicated band pass filter per channel, an integrated PureBand Crossover System, and Peakx Limiters to provide maximum output while protecting your speakers.

For inputs, the rear panel includes a pair of XLR-3F connectors, 1/4" and RCA inputs for flexible connections with a selectable input sensitivity of either 1.4 Vrms or 0.775 Vrms. Outputs are provided on both speakON and binding post connectors.

You can set the amplifier's sleep mode for a designated period of time without having to press a button, as well as turn off all LED indicators except for clip and thermal to reduce distractions in dark venues. A security mode can be engaged to disable menu buttons, which can be locked and unlocked by entering a combination code. Full system reset allows for factory settings to be restored and a remote power trigger allows you to turn the unit on and off.

Crisp Sound

By Andreas
Rated 5 out of 5
Date: 2025-11-12

I've Used These In A Couple Of Fitness Studios. After Replacing The Old Amps In The Studios With These, The End-users (instructors) And Their Customers Note That The Audio Sounds A Lot Cleaner And Crisper Than Before. The Studios Aren't Pushing These 2502s Particularly Hard So I Suspect They'll Have Long, Easy Lives.

Excellent amplifier

I own 2 XLS 2502 amplifiers and a Crown XLS 2500. I purchased them for sound reinforcement but have listened to them through my Martin Logan electrostatic speakers using a McIntosh MX136 to drive them. These amplifiers are sonically very neutral with none of the classic class D brightness one often finds. The XLS2502 amps are extremely powerful and quiet, provided you use the XLR connections. The RCA connectors do seem to pickup some ground loop noise. These amplifiers have much higher gain than my Adcom GFA 5802 amplifiers and if you use RCAs, in a high resolution stereo, consider reducing the input gain controls to about 3/4s full. This lowers the RCA noise floor to an acceptable level. The XLR connectors are dead quiet. Resolution of low level detail is good and the soundstage in stereo is both wide and deep. The top end is very smooth and polite. I slightly prefer the Adcom amplifiers but without a direct AB reference, I would be happy with the Crowns in my system.

How loud are the fans when playing at high volumes?
Asked by: dennis
The fan used is specified at 28.3 db/A. An engineer at Crown did a test and was getting between 71 and 75 dB right at the fan, and about 45-55 dB at 1 meter. The test was done in a lab with multiple amps and DSPs running in the background as well; so the unit alone would be much quieter.

what will be the RMS wattage be with 6 ohm ...

what will be the RMS wattage be with 6 ohm speakers, eg, cerwin vega xls 15 ?
Asked by: JAMES
Crown has not provided wattage ratings for 6 ohms, but they do list ratings for 4 and 8 ohms. We can use the specs listed for peak wattage to calculate RMS wattage at 4 and 8 ohms. 6 ohms is going to be right in the middle so you can get a better idea of how it would perform with your speaker. At 4 ohms, the XLS 2502 is rated at 775W per channel and 2400W bridged for peak power, which works out to approximately 550W per channel and 1700W bridged for RMS power at 4 ohms. At 8 ohms, the XLS 2502 is rated at 440W per channel and 1550W bridged for peak power, which works out to approximately 310W per channel and 1100W bridged for RMS power at 8 ohms.

Is that 775watts at hz or khz?

Is that 775watts at hz or khz?
Asked by: dennis
Neither. The power rating for an amplifier is not related to the frequency response. The 775 Watt power rating for the Crown XLS 2502 Stereo Power Amplifier is for each channel when the amp is operating at 4 Ohms. This means the amp will deliver 775 Watts to each channel to drive a 4 Ohm speaker. The maximum power the amp can output will vary depending on the impedance of the speakers that are connected. With an 8 Ohm speaker the amp delivers 440 Watts per channel and with a 2 Ohm speaker the amp delivers 1200 Watts per channel. When speakers with lower impedance ratings are use the amp will deliver higher amounts of power.

I am thinking of running the amps in bridged mode, can put one amp on top of the other without causing heating problems. I don't have a rack.
Asked by: dennis
For proper venting, it would be best to leave them side by side if you don't have a rack.

How does the remote trigger work? Is it a separate piece of hardware? Is it signal sensing?
Asked by: Mark
Is the xls 2502 stronger than an xli 3500 or vice versa?
