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 has four potentiometers and with default program loaded. Customers can adjust the gain, bass, midrange and treble.

It also have a debug port for Sigima Studio, User can program this module with our USBi programmer to get more functions which includes equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc.

Warning: You need disconnect the soldering pads on the board back side when you connect external potentiometers. Or the ADC port may burned. Potentiometers value: 1Kohm-100Kohm.
