Speaker presets, an LCD screen, and a universal power supply!700W/ch @ 2 ohms, 500W/ch @ 4 ohms, 275W/ch @ 8 ohms, 1,400W bridged mono @ 4 ohms, 1,000W bridged mono @ 8 ohms. The XTI Series of Crown amplifiers are professional tools designed and built for portable PA applications. All are rugged, lightweight, and feature an LCD screen with DSP speaker presets for crossover frequencies, EQ, limiting, delay, 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.
