Crown XTi4000 2u 1200W@4ohm £859.98
Description
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.
