ed to be used with a vinyl turntable equipped with analog outputs (RCA). It provides the dual function of preamplifier and RIAA. This circuitprovidesa total of fourspeakers4 ohmsand40Wat12vpowered. It is thereforeidealfor usein the car. Totalharmonic distortionis rather high, about 10%at full power. Butwithhalf the powerrequirements(20W)is lessthan 2%. Anyway itis not intendedtohave ahigh performancesystemin the car. With theintegratedaudioTDA8571Jdesignedforautomotive applications, this 40w amplifier circuit can expandthe soundof the car radioorconnecta.
