Description
TSA1700 Audio DSP Board
The TSA1700 is a complete audio digital signal processing module. The main DSP chip on this module is ADAU1701. The application range is active loudspeaker concepts (digital 3-way 3-unit, 2-way 2-unit crossover, bass enhancement, etc.), and transformation from 2.0 to 2.1 is realized. It also has four potentiometers, and with the 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 access additional functions, such as equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc.
