This amplifier is a member of the XTI range of Crown Amps. These amps are professionally designed and made for portable PA applications. The range has 3 different models which are the same but with differing power outputs.

They are the Crown XTI 4000, Crown XTI 1000 and the Crown XTI 2000. They are all tough and low weight and really do offer excellent value against similarly matched amps. These amps have an LCD screen and speaker presets for crossover frequencies EQ limiting delay and a subharmonic synthesiser. Their other features include a switchmode universal power supply, function indicators. Speed fan-assisted cooling, Speakon and binding-post outputs, short-circuit protection and XLR inputs. Their robust qualities give reliability and handle 2 ohm loads and means you get real pumping lows

 

Running down the main features of the Crown XTI 4000 includes:

  • Speaker preset integration with an LCD front panel display
  • An extremely low distortion giving reproducing excellent music and voice.
  • Advanced protection circuits protect against: shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal faults
  • Very versatile handling of a very wide range of speaker impedances and outputs
  • Switch-mode universal power supply
  • Speaker presets for crossover frequencies, EQ, limiting, and delay
  • Fits in 2U of rack space and weighs under 9kg; this sets a new hgh standard for lightweight amplifiers.
