FEATURE：

A. 96KHz / 192Khz sampling rate switching, with both functions, brings more application scenarios. B. Dynamic equalizer is automatically optimized for large signal or small signal. C. FIR filter can perfectly correct the phase distortion caused by system parameter adjustment. D. The delay of each channel is up to 1200ms, and the precision is optimized to 0.01ms with the fine adjustment of sound field or phase. E. 4-way input and 8-way output, complete routing assignment, can be set to multiple working modes. F. Color LCD display, real-time dynamic level display, Chinese and English interface optional. G. One key mute and global total volume control. H. Equipped with WiFi / RS485 central control and drive free USB control interface, which can be adjusted by the control software at the PC.
