||Crown XTi Series Amplifiers
The Crown XTi Series amplifiers
are professional tools designed and built for portable PA applications and offer
unmatched value in their class. There are three models in the series which are
identical except for output power and all of which are enclosed in a rugged, lightweight,
2U rack mounting chassis that incorporates the best of design principles and innovative
features. 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 and proportional-speed
fan assisted cooling. Advanced protection circuitry guards against shorted outputs,
open circuits, DC, mismatched loads, general overheating, high-frequency overloads
and internal faults. With their powerful, reliable performance, XTi-Series amps
easily handle 2-ohm loads and are capable of chest-thumping lows.
