Crown XTi1000 Power Amplifier

Crown XTi1000 Power Amplifier

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.
