Crown XLi 3500 - 1350W 2-Channel at 4-Ohm Power Amplifier

The Crown XLi 3500 is the most powerful model in the XLi Series of power amplifiers, offering 1350 watts of output per channel at 4 ohms, 1000 watts per channel at 8 ohms, and an impressive 2700 watts in bridged mono mode at 8 ohms. This makes it ideal for musicians, DJs, entertainers, and various venue applications such as houses of worship, discos, and pubs. The XLi 3500 combines affordability with professional-grade features and rugged construction, ensuring reliable performance and high-quality sound in demanding environments.

Designed with versatility in mind, the XLi 3500 operates in stereo, parallel, or bridge-mono mode, giving users flexibility in configuring the amplifier for different sound setups and environments. Whether powering a large speaker system or delivering high-fidelity sound in smaller venues, this amplifier provides exceptional output and sound clarity. The XLi 3500's efficient forced-air cooling system ensures it can perform at high power levels without overheating, making it suitable for extended use in live performances, installations, and events.

The amplifier includes both RCA and XLR input connectors, allowing easy integration with various audio sources and systems. User-selectable input sensitivity of either 0.775V or 1.4V offers compatibility with professional and consumer audio equipment, ensuring optimal performance in a wide range of applications. The XLi 3500's output section features Speakon and binding post connectors, providing secure and flexible speaker connections to suit different setups.

To protect the amplifier and connected speakers, the XLi 3500 incorporates a suite of protection features, including safeguards against shorts, no-load conditions, on/off thumps, and radio-frequency interference (RFI). These built-in protections ensure the long-term durability and reliability of the amplifier, even in challenging operating conditions. The amplifier's rugged build quality, along with its solid internal components, makes it a dependable choice for mobile and fixed installations alike.

The front panel of the XLi 3500 is equipped with two independent level controls, making it easy to adjust the output levels for each channel. The power switch and LED indicators provide clear operational status, while six additional LEDs per channel give real-time feedback on signal presence, clipping, and fault conditions. These indicators allow for quick diagnostics and monitoring, ensuring that the amplifier is operating correctly and minimizing the risk of damaging speakers or the amplifier itself.

With a frequency response range of 20Hz to 20kHz (+0/-1dB), the XLi 3500 ensures accurate and detailed audio reproduction, making it suitable for a wide variety of sound reinforcement applications. Its low total harmonic distortion (THD) of less than 0.5% and intermodulation distortion (IMD) of less than or equal to 0.35% ensure clean and precise sound, even at high output levels. The amplifier's slew rate of greater than 10V per millisecond guarantees fast response to dynamic audio signals, producing crisp and clear audio with minimal lag.

The XLi 3500 offers a voltage gain of 36 dB and a damping factor of greater than 200, providing tight control over speaker drivers for enhanced bass response and overall sound quality. Its signal-to-noise ratio of over 100dB ensures quiet operation, minimizing background noise and delivering professional-grade sound clarity. With crosstalk ratings of -75 dB at 1kHz and -59 dB at 20kHz, the amplifier ensures excellent channel separation for immersive stereo sound.

The XLi 3500 is built for durability and portability, weighing 43 lbs and fitting into a standard 2U rack space (19 x 14.4 x 3.5 inches). Its robust construction and compact size make it easy to transport and install, whether in a permanent setup or for mobile use. The amplifier is designed to operate on standard 120V, 60Hz AC power, making it compatible with most North American electrical systems.

In conclusion, the Crown XLi 3500 is a high-powered, reliable, and versatile amplifier that delivers professional-grade sound performance at an affordable price. With its comprehensive feature set, rugged design, and built-in protections, the XLi 3500 is an excellent choice for musicians, DJs, entertainers, and venues that demand high-quality audio amplification.
