2.支持信号输入音量增益大小调整方便匹配各种设备电平不同电平输入                                                                                                       

★3.支持4路输出，2路平衡输出和2路6.35不平衡输出                                                                                                          

4.具有输出增益高低可选，方便设备选择调音台前输入或调音台后输出操作选择性强                                                                                        

5.输出设有高音提升和衰减可调节控制键，能很好匹配音箱使人声更好更加突出                                                                                         

★6.支持智能风冷散热，为使本机能长时间稳定运行而增加的对流式设计风冷散热系统，有效保障设备的长时间工作稳定性，而不会出现热机死机现象                                         

7.整机操控面板简约直观，只有一键选择直通信号和防啸叫处理信号切换，极大简化系统调试流程                                                                          

8.完全傻瓜式操作，内置的先进浮点DSP数字算法处理器自动跟踪消除啸叫频点                                                                                     

9.操控面板上具有信号过载PEAK指示、信号动态状态指示、
