Crown Xti 4000 STEREO POWER AMPLIFIER

Xti 4000 STEREO POWER AMPLIFIER description:

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
