Crown XTi4000 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, Speakonå¨ 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 Ûªs Three-Year, No-Fault, Fully Transferable Warranty.
