DSP Module
A professional digital audio processing module with 8 inputs and 8 outputs based on digital signal processing technology. This processing module adopts ARM processor with embedded operating system, all-digital audio processing algorithm and debugging system to achieve beautiful sound effect and simple and intuitive debugging mode, and can modify any frequency point on music or human voice.
Each input has audio processing modules such as 31 parametric equalization and noise gate, which can modify and compensate the characteristics of the sound box, making the sound reinforcement system better adapt to the acoustic characteristics of the building environment. Each output channel has 10 segments of parameter equalization, high-low pass filter, compressor and limiter, which can limit the output signal size and avoid the overload of the rear stage equipment for a long time to protect the power amplifier and speaker.
