When you choose Crown's XTi 2 Series, you're choosing one of the most powerful and innovative amplifiers on the market today. With such innovations as a universal tracking switch-mode power supply and a fully integrated suite of speaker processing tools, these amps are at the top of their class when it comes to thermal efficiency and system flexibility.

You also have greatly improved control capabilities. The addition of Peak x Plus Limiters gives you full command over threshold, attack and release, and we enhanced the Subharmonic Synth so you can easily manage frequency, gain and filter type, allowing for application-specific tuning.

Plus, you'll now be able to tailor fan speed for specific applications and have software visibility of the Power Supply Temperature and AC Line Voltage. Combine all of that with integrated cast-aluminum rack handles for maximum durability and portability and you have the power to move you – and the world.

• Integrated Processing
  
• 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.
  
• Peak x 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.
