Crown XTi 4000 Stereo Power Amplifier

The Crown XTI 4000 Amplifier. Powerful, reliable performance, rugged and lightweight for portable PA applications.

The Crown XTI 4000 is a part of the XTi Series of Crown amplifiers, 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 speaker presets for crossover frequencies, EQ, limiting, delay, and a subharmonic synthesizer. Other features include a switchmode 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. The main features of the Crown XTI 4000 include:

* Integrated speaker presets with LCD front panel display

* Accurate, uncoloured 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

* Fits in 2U of rack space and weighs under 19 pounds; weight sets a new standard in lightweight amps
