TDA2822 made for 5.1 audio amplifier system

Circuit combination of the 3 IC TDA2822  above can be used for 5.1 audio power amplifier system with low power output . The input signal used is analog signal not digital (SPDIF) , so it needed some input to the jack input. The speakers are suitable for use have impedance 8 Ohms , and with power 4 Watt, to Left , Right , Rear pair , center , and subwoofer speakers. To run this circuit , is also required circuit for volume control as tone control.
