Nuevo XTi 2 (Segunda Generacion)

XTi

There's no debate – when you choose Crown's XTi 2 Series, you're choosing one of the most powerful and innovative amplifiers on the market today. That's because the all-new XTi 2 Series amps continue to set the standard for unmatched performance and value, delivering the goods night after night without breaking a sweat.

Next generation features:
  • Peakx Plus™ Limiters provide the ultimate in system performance and protection by allowing full control over threshold, attack, and release
  • Enhanced Subharmonic Synth section provides user control over frequency, gain and filter type for system-specific tuning
  • 3 User-defined fan mode controls – normal, early and fullspeed – for matching fan performance to a specific application
  • New system monitoring provides software visibility of AC line voltage and power supply temperature
  • Integrated cast-aluminum handles for easy handling and enhanced durability
  • Locking power cord clip provides a secure connection between the amplifier and power cord
  • Updated HiQnet Band Manager™ and System Architect™ control software
  • Increased number of presets to a total of 30; 29 of which are user definable


PERFORMANCE
 
Input EQ:
6 parametric filters per channel with adjustable Q, ±15 dB boost/cut. Also adjustable high and low shelving filters. This 8-filter EQ section can be bypassed.

Crossover Filters:
Highpass and Lowpass per channel. Butterworth 6/12/18/24 dB per octave. Linkwitz-Riley 24/48 dB per Octave. Also includes ± 15 dB bandpass gain and polarity control.

Output EQ:
8 parametric filters per channel with adjustable Q, ±15 dB boost/cut. This 8-filter EQ section can be bypassed.

Delay:
For signal alignment of driver; 50 mS of total delay.

SubHarmonic Synth:
Takes the low-frequency content of the input signal and "synthesizes" a new signal that is the same as the input signal but one octave lower. The new synthesized signal is then mixed with the original signal to create the effect. New: Users now have control over frequency, gain, and filter type.

Peakx™ Plus Limiter:
User defeatable limiter that allows users to control Threshold, Attack, and Release times.

Presets
30 total presets, 29 of which are user-definable.
