Crown XTI4000 Power AmplifierCrown XTI Power Amplifiers are rugged and lighweight power amps that offer unmatched value in their class.
The series includes three models which are identical except for output power: XTI 1000, 2000 and 4000. All are professional tools designed and built for portable PA applications.
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. Dimensions: 3.5 x 19 x 12.25 inches.
