CROWN / XTi 4002

The CROWN (AMCRON) / XTi4002 is a power amplifier equipped with a high-performance DSP that can drive large speakers with high output performance. Various settings such as crossover, equalizer, delay, and limiter can be set on the LCD display. Using the dedicated software Band Manager 2, more advanced settings are possible on a PC.

The "XTi 4002" is equipped with a high-performance DSP, and can execute various audio processing with one unit without preparing a separate processor. The crossover slope can be freely selected from Butterworth (6,12,18,24,48dB / oct) or Linkwitz Riley (24,48dB / oct), and the frequency can be set to any value in 1Hz steps. Each channel also has a parametric EQ with 8 input points + 6 output points and a delay of up to 50mS. In addition, a sub-harmonic synthesizer that synthesizes ultra-low frequencies based on the input signal and outputs powerful heavy bass is also installed.

Up to 49 DSP settings can be saved as presets in the main unit and recalled instantly, making setup quick and easy. Equipped with a convenient pink noise transmitter for checking the system. Detailed DSP settings and presets can be saved from HiQnet System Architect software on a USB-connected PC. HiTinet Band Manager software dedicated to XTi is also available.

The "XTi4002" has an output performance that exceeds the class in a lightweight and compact body. Equipped with a high-efficiency switching power supply that generates less heat, 1,600W + 1,600W in a 2Ω stereo, and 3,200W output in a 4Ω bridge mono. Drive large speakers with a margin. In addition, the Peak X Plus limiter, which allows detailed settings for threshold, attack, and release, maximizes output performance. It is also lightweight and easy to carry, making it ideal for temporary PAs.

“XTi 4002” input signals can be routed inside the unit. A link terminal for splitting the input signal is also provided. The output prepared two terminals, a binding post and a speed controller. In addition, the front panel has a large backlit LCD display for recalling presets and DSP settings. A lock function that prohibits operation of the display is also provided. Additionally, the handle is integrated with the cast aluminum front panel for easy portability.
