Crown XTI1000

The XTI Series of Crown amplifiers are professional tools designed and built for portable PA applications. The series includes three models which are identical except for output power: XTI 1000, 2000 and 4000. All are rugged and lightweight, and offer unmatched value in their class.

XTI-Series amplifiers feature an LCD screen with DSP speaker presets for crossover frequencies, EQ, limiting, delay, and a subharmonic synthesizer. Other features include a switch-mode universal power supply, useful function indicators, proportional-speed fan assisted cooling, XLR inputs, Speakon® and binding-post outputs, short-circuit protection and more.

With their powerful, reliable performance, XTI-Series amps easily handle 2-ohm loads and are capable of chest-thumping lows. Plus, your investment in an XTI-Series amplifier is backed by Crown’s Three-Year, No-Fault, Fully Transferable Warranty.
