· 厚重大气的3U结构设计,抗震性极好,坚固耐用,故障率低。

· 全平衡超动态重驱技术，在驱动重负载时声音表现自如。

· 信号和削波发光LED指示灯可监视功放的工作状态

· 高信噪比（100dB以上），噪声极低。

· 多重叠加综合保护电路包括延时电源起动，DC（直流）、过流、过压、

   过热、动态自动限幅保护，使功放工作正常稳定。

· 大功率双速风扇随音乐的变化自动调速，有效的节能和降低机内温度，提高系统可靠性。

· 经典的两种工作模式立体声/桥接满足不同系统的搭配。 

XLI2500/XLI3500/XLI4500 features:

* The 3U srtucture design, with good function of resist-shake, sturdiness,durability and low malfunction rate. 

* Dynamic full-balance of ultra-wide drive technology can make natural sound when driving heavy loads.

*  High SNR(above 100db), low noise.

* The signal and shining LED clip indicator can monitor work status of the amplifier.

*  Full-automatic protection circuit which including DC,overcurrent,overvoltage、overheating and dynamic automatic limitation protection, ensure the stabilization and efficience of the amplifier.

* The double-speed and high-power fan automatically reduce inner temperature and enhance the reliability of the system.

* The classical work mode of stereo /bridge meet the different system request.
