Crown XTI2000 Xti Series 1000 Watt Amp

CROWN XTI Details ^top

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.

Features

• Integrated proprietary DSP with LCD front panel display

• Accurate, uncolored sound with very low distortion for the best in music and voice reproduction

• Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal faults

• Extremely versatile, handling a wide range of speaker impedances and outputs

• Switch-mode universal power supply

• Speaker presets for crossover frequencies, EQ, limiting, and delay

• All products fill 2U rack spaces and weigh under 17 pounds; weight sets a new standard in lightweight amps (20% less)

• Speakon® and binding post outputs, XLR inputs and loop-thrus

• Comprehensive LED status per channel

• Three-Year, No-Fault, Fully Transferable Warranty completely protects your investment and guarantees its specifications

The power ratings per channel for the XTi Series are as follows:

• XTi 1000 is 500 watts per channel at 4 ohms

• XTi 2000 is 800 watts per channel at 4 ohms

• XTi 4000 is 1200 watts per channel at 4 ohms
