Product Description:

SA3082 is a professional digital audio processor based on digital signal processing technology, with 8 inputs and 2 outputs. This processing module uses ARM processors in conjunction with embedded operating systems, fully digital audio processing algorithms, and debugging systems to achieve beautiful sound effects and simple and intuitive debugging methods. It can also modify any frequency point on music or vocals.

Each input channel of SA3082 has 31 audio processing modules such as parameter equalization and noise gate, which can finely modify and compensate for the characteristics of the speaker, 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 and low pass filters, compressors, and limiters, which can limit the size of the output signal and avoid long-term overload of downstream equipment to protect the amplifier and speaker just now.

Suitable for audio processing in large and small conference rooms, can concentrate conference room audio processing into a tablet control system
