The Crown XTi 4002 is a professional two-channel power amplifier designed to deliver powerful, reliable audio performance for live sound reinforcement, touring systems, DJ applications, theaters, and installed sound environments. Part of Crown's XTi 2 Series, the XTi 4002 combines high-output amplification with integrated digital signal processing (DSP), advanced loudspeaker protection, and an efficient, lightweight design.
Delivering 1,200 watts per channel at 4 ohms, the Crown XTi 4002 provides the power needed to drive professional PA speakers, stage monitors, and subwoofers. With flexible amplifier configurations and onboard processing, it allows audio professionals to optimize system performance without requiring separate external signal processors for many common applications.
Powerful Two-Channel Amplification for Professional Sound Systems
The Crown XTi 4002 provides two independent amplifier channels with output ratings of 1,600 watts per channel at 2 ohms, 1,200 watts per channel at 4 ohms, and 650 watts per channel at 8 ohms.
This versatility makes it suitable for a wide range of professional loudspeaker configurations, including full-range PA systems, passive stage monitors, and subwoofer applications.
The amplifier supports stereo, bridge-mono, and other configurable operating modes, providing flexibility for different system designs and power requirements.
Integrated DSP for Precise Loudspeaker Control
The XTi 4002 includes advanced digital signal processing designed to simplify loudspeaker management and system optimization.
Built-in crossover filters, equalization, delay, and limiting functions allow installers and audio technicians to tailor amplifier output to the connected loudspeakers.
Crown's Peakx Plus limiters provide adjustable output protection, helping control excessive signal levels while maintaining consistent audio performance.
The amplifier also includes an enhanced subharmonic synthesizer with adjustable frequency, gain, and filter settings for applications requiring additional low-frequency impact.
Efficient Design for Touring and Installed Audio
The Crown XTi 4002 features an efficient switch-mode power supply and a rugged, lightweight chassis suited for demanding professional audio environments.
Its compact rackmount design helps reduce equipment weight compared with many traditional high-power amplifiers, making it practical for mobile sound systems and touring racks.
Three selectable fan modes—Normal, Early, and Full Speed—allow users to adjust cooling behavior according to operating conditions.
Integrated cast-aluminum handles and a locking power cord clip add convenience and durability for frequent setup and transport.
System Monitoring and Amplifier Configuration
The XTi 4002 includes a front-panel interface for accessing amplifier settings, monitoring operating conditions, and configuring DSP functions.
System monitoring features include AC line voltage and power supply temperature readouts, allowing technicians to monitor amplifier operation during demanding performances.
Compatibility with Crown's HiQnet System Architect software provides additional configuration and control options for supported computer-based workflows.
