The TSA1701 is a complete audio digital signal processing module. The main DSP chip on this module is ADAU1701. The application range from active loudspeaker concepts (digital 3 way 3 unit, 2 way 2 unit crossover, bass enhancement, etc.) and realize the transformation from 2.0 to 2.1. It also has four potentiometers and with default program loaded. Customers can adjust the gain, bass, midrange and treble.
It also has a debug port for Sigima Studio, and user can program this module with our USBi programmer to get more functions that include equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc.
