It consists of multitrack audio amplifier IC, microcontroller PIC 16F73, DAC, speaker, etc. Normally in audio amplifiers, the base, problems in different tracks are adjusted by variable resistors. In this project the variable resistors are constructed in a digital way.
The microcontroller produces digital signal and the DAC section produces the corresponding analog voltage. This analog voltage is given to the particular Audio IC track. Therefore, the base / problem of the particular track can be changed.
In this way, we can operate multiple tracks in a digital system. The output of the audio amplifier is output to the corresponding speakers. The microcontroller used is the PIC 16F73 and the program of the microcontroller is written in assembly language
