TA8210 based on the circuit input in addition to the mix, there mic mp3 player can be connected circuit with 12 volts works only source fed mixer circuit used in the opamp NE5532 Feed dredging simple with regula made instead L7805 Regulator integrated use more healthy quality leads 🙂
Also made with TA8210 amp circuit also has a somewhat simpler
