The XTi 4002 power amplifier from Crown delivers an unprecedented level of power and performance for installed sound systems and live productions. With its innovative Peakx Plus Limiters, enhanced subharmonic synth section and advanced thermal control, the XTi 4002 offers complete command over your system’s sound.
Peakx Plus Limiters Enable Ultimate Control
The XTi 4002’s Peakx Plus Limiters provide total control over threshold, attack and release for optimized system protection and performance. Set your levels with confidence knowing the XTi 4002’s limiters are actively monitoring signal levels to prevent distortion and ensure pristine sound quality.
Enhanced Subharmonic Synth for Application-Specific Tuning
The XTi 4002 features an enhanced subharmonic synth section with controls for frequency, gain and filter type. Easily tune your system’s subharmonic frequencies for the specific demands of your application whether for a house of worship, theater production or other venue.
Advanced Thermal Control for Optimized Efficiency
Three user-defined fan modes – normal, early and full speed – give you flexibility in matching the XTi 4002’s cooling performance to your particular needs. Keep things running efficiently by selecting higher fan speeds for more demanding applications and lower speeds for less intensive uses. Advanced system monitoring provides real-time data on AC line voltage and power supply temperature for complete visibility into your system’s performance.
Remotely Manageable and Built-to-Last
The XTi 4002 works with HiQnet Band Manager and Audio Architect control software for simple remote setup, configuration and monitoring. Its integrated cast-aluminum handles provide maximum durability for handling and racking the amplifier. With Crown’s XTi 4002 power amplifier, you have the power and control to shape sound and move audiences.

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.
