Crown XLi 2500 - 750W 2-Channel at 4-Ohm Power Amplifier

The Crown XLi 2500 is a powerful and versatile 2-channel power amplifier, designed to provide professional-grade audio performance for a wide range of applications, including musicians, DJs, entertainers, houses of worship, discos, pubs, and more. Part of Crown's XLi Series, the XLi 2500 offers an excellent balance of power, reliability, and affordability, making it an ideal choice for those seeking a dependable amplifier with plenty of features.

Delivering 750 watts per channel at 4 ohms, 500 watts per channel at 8 ohms, and a robust 1500 watts in bridged mono mode at 8 ohms, the XLi 2500 provides the flexibility and power necessary for a variety of speaker configurations. The amplifier supports stereo, parallel, and bridge-mono modes, allowing users to adapt to different sound setups and environments, whether for live performances, installations, or mobile sound systems.

The XLi 2500 features user-selectable input sensitivity settings, allowing users to choose between 0.775V or 1.4V, making the amplifier compatible with a wide range of audio sources. This flexibility ensures that the XLi 2500 integrates easily into any system, whether used with professional mixers or consumer audio devices. The amplifier is equipped with both RCA and XLR inputs, providing convenient connectivity options, while Speakon and binding post outputs ensure secure and reliable speaker connections.

Built for long-term reliability, the XLi 2500 includes a number of protection features designed to safeguard the amplifier and connected speakers. This includes protection against shorts, no-load conditions, on/off thumps, and radio-frequency interference (RFI), ensuring consistent and dependable performance even in challenging environments. Additionally, the amplifier's forced-air cooling system prevents excessive thermal buildup, keeping the amplifier running smoothly even during extended periods of use at high power levels.

On the front panel, the XLi 2500 is equipped with two independent level controls, allowing precise adjustment of each channel. The power switch and power LED are easily accessible, while six LEDs per channel provide clear visual feedback on signal presence, clipping, and fault conditions, enabling users to monitor the amplifier's status at a glance. These indicators ensure that any potential issues are quickly identified and addressed, reducing the risk of damage to the amplifier or speakers.

With a frequency response of 20Hz to 20kHz (+0/-1dB), the XLi 2500 ensures full-range audio reproduction with minimal coloration, making it suitable for a wide variety of audio applications. Its total harmonic distortion (THD) of less than 0.5% across the entire frequency range ensures clean, accurate sound, while the intermodulation distortion (IMD) rating of less than or equal to 0.35% further enhances audio fidelity by reducing distortion during complex signal reproduction.

The XLi 2500 features a slew rate greater than 10V per millisecond, which ensures fast response to dynamic signal changes, delivering crisp, detailed sound, even with rapid transients. The amplifier's 33 dB voltage gain and damping factor of over 200 provide precise control over speaker drivers, resulting in tight, well-defined bass response and smooth overall sound. The signal-to-noise ratio of greater than 100dB ensures that unwanted background noise is minimized, contributing to a clean, professional sound quality.

With a crosstalk rating of -75 dB at 1kHz and -59 dB at 20kHz, the XLi 2500 offers excellent channel separation, preserving the stereo image and delivering clear, distinct audio from each channel. The amplifier's input impedance of 20 kOhm (balanced) and 10 kOhm (unbalanced) ensures compatibility with a wide range of audio equipment, while the AC line voltage and frequency rating of 120V, 60Hz makes it suitable for use in standard North American power systems.

The Crown XLi 2500 is built with durability and portability in mind, featuring a sturdy construction that ensures reliable performance over time. Weighing in at 29.7 lbs and measuring 19 x 12.4 x 3.5 inches, the amplifier fits into a standard 2U rack space, making it easy to integrate into existing setups or transport between gigs.

In summary, the Crown XLi 2500 is a versatile, powerful, and reliable amplifier that delivers professional-grade sound quality and performance in a durable, easy-to-use package. Its combination of features, including selectable input sensitivity, multiple input and output options, and advanced protection circuitry, make it an excellent choice for anyone in need of a high-quality power amplifier for live sound or installation applications.
