AT88N DIGTAL AUDIO MXTRIX PROCESSOR
Application: Description:It adopts advanced DSP processing technology and has new algorithms such as automatic mixing and feedback cancellation to solve various practical problems in application scenarios. Since most of the controls are operated by software, the appearance can be more concise and bright. The operator only needs to click the mouse lightly, and no longer need to adjust the complex large-scale mixer on the spot to complete the function conversion, which greatly simplifies the difficulty of operation.
