The XTi Series of Crown amplifiers are 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 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.
Integrated proprietary DSP with LCD front panel display
