Crown XTi Series Amplifers

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.


Features

  • Accurate, uncolored sound with very low distortion for the best in music and voice reproduction
  • HiQnet USB Connector, type B, connects to a HiQnet network.
  • Switch-mode universal power supply.
  • Integrated proprietary DSP with LCD front panel display.
  • Backlit liquid crystal display shows speaker presets.
  • Three buttons below LCD screen for accessing menu items.
  • Speaker presets for crossover frequencies, EQ, limiting, and delay.
  • Precision detented level controls on front panel, one per channel.
  • Power switch on front panel.
  • LED indicates when power is on.
  • LED indicator for signal presence, -10 dB, -20 dB, and clip for each channel
  • LED indicator for temperature/fault status for each channel.
  • LED indicates when amplifier ready to produce audio for each channel.
  • Electronically balanced inputs with XLR connectors.
  • Touch-proof binding post and Speakon output connectors.
  • Extremely versatile, handling a wide range of speaker impedances and outputs.
  • Output power between 275W and 1,600W per channel depending on model and load.
  • Efficient proportional-speed forced air cooling to prevent excessive thermal buildup.
  • Rugged all-steel 2U chassis construction.
