About the Crown XLi 3500
The Crown XLi 3500 is the no-nonsense two-channel power amp that has been the entry point to "real touring power" for two decades. 1350W per channel @ 4Ω, no fancy DSPDigital Signal Processing — the number-crunching that does EQ, compression, and effects inside a box. More DSP means more processing at once., no networking — just clean analog amplification with bridge-mono switchable for sub duty. Lives in regional touring rigs, schools, churches, practice rooms, and house systems where simplicity and bulletproof reliability beat features.
The Crown XLi 3500 is a two-channel analog power amplifier that has been earning its rack space in regional touring, house systems, and school auditoriums for a long time. It does one thing: take a line-levelThe strong signal that runs between pieces of gear (about a volt) — hotter than mic level, far below speaker level. signal and push serious wattage to speakers — 1350 watts per channel into 4 ohms, or bridged into mono for sub duty. There is no onboard DSPDigital Signal Processing — the number-crunching that does EQ, compression, and effects inside a box.

If you already have a proper processor or crossoverSplits audio into frequency bands so each speaker only gets what it can handle — lows to the subs, highs to the horns. upstream, this amp just gets out of the way and delivers power.
At 14 kilograms and 365mm deep, this is a legitimate chunk of iron in a 2UThe standard slice of rack height: 1U = 1.75″. A 3U box takes three slices; half-rack gear pairs two units side by side in one. frame — plan your rack depth and confirm your rails can take the weight before you commit a shelf position. Idle draw is 350 watts, peaking at 1350 watts under load, so on a shared circuit with other gear you need to do the math before load-in, not during. Inputs accept XLRThe standard 3-pin locking connector for mics and balanced line signals — pin 1 is the shield, pins 2 and 3 carry the balanced pair. or quarter-inch on both channels, which is useful when your patch runs out of tidy options. Speakon outputs are the right call for anything carrying real wattage to a cabinet.
This amp belongs in a rig where budget is real, the signal chain already has processing, and reliability over hundreds of shows matters more than remote monitoring or built-in limiting.

In the rack
- Bridge it for sub duty by using the bridge-mono switch and feeding your subwoofer from the left Speakon output — just make sure your sub cabinet is rated for the impedanceOpposition to signal flow, in ohms. Low-impedance IEMs are easier to drive loud; mismatches shift level and tone. you are presenting in that mode.
- At 14kg, this amp will flex a shallow rack shelf. Either use a deep rack bag with proper rear support or ensure your road case has a full rear rail — let the rails carry the weight, not the front ears.
- Account for the 1350W peak draw before load-in: on a standard 15A circuit shared with a console, a stage boxThe I/O endpoint on stage: mics plug in there and one digital line (AES50, Dante) carries everything to the console.
