TSA1702A is a DSP audio board, it can be powered by a microUSB cable or any DC9V-30V power supply. The TSA1702A 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 has a debug port for Sigima Studio, and users can program this module with our USBi programmer to get more functions that include equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc.

Control buttons:

Not support this function on TSA1702A

 

Potentiometers port:

You can connect external POTs (5K~20K) to control the Main volume, treble, middle, Bass. This is our POT kit

  1. ADC0- Main volume.
  2. ADC1- Bass volume.
  3. ADC2- Middle volume.
  4. ADC3- treble volume.

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

 

DSP programming port:

TSA1702A's DSP detects both Bluetooth signal and Line in signal, but the default program makes Bluetooth has higher prority. If Bluetooth signal is detected, TSA1702B will output Bluetooth audio source, otherwise it will output Line in audio source. You can develop DSP program to fulfill your requirement, then load the new DSP program by using USBi JTAG Sigma DSP programmer.
