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 wa y 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 Sigma Studio, users can program this module with our USBi programmer to get more functions which includes equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc. Pins define: Port name Pin name Direction Description External Potentiometers port 3.3V Power Out 3.3V Output A_ADC1 Analog In Treble control A_ADC2 Analog In Midrange control A_ADC3 Analog In Bass control A_ADC0 Analog In Gain control GND - Audio Input GND - ADC1 Analog In Right channel ADC0 Analog In Left Channel Audio Out1 GND - DAC0 Analog Out Left Channel DAC1 Analog Out Right channel Audio Out2 GND - DAC2 Analog Out Left Channel DAC3 Analog Out Right channel Tinysine AMP sub control Port Line Out0 Analog Out DAC0 Line In0 Analog In ADC0 GND - GND - Warning: You need disconnect the soldering pads on the board back side when you connect external potentiometers.
