Crown XTi2000 Power Amplifier

Wikispecs.org - The Largest Product Database,the biggest product specifications database in the world

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.

Protection XTi-Series amplifiers are protected against shorted, open or mismatched loads; overloaded power supplies; excessive temperature; chain destruction phenomena; excessive output current, input overload damage; and high-frequency blowups. They also protect loudspeakers from input/output DC, large or dangerous DC offsets and turn-on/turn-off transients.
