The XTi Series of Crown amplifiers are professional tools designed and built for portable PA applications. The series includes 3 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 3-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 lbs.; 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
3-Year, No-Fault, Fully Transferable Warranty completely protects your investment and guarantees its specifications
