curve (a) is valid when the receiving amplifier is not driven or when MUTE =LOW (Contek TEA1062 is
HIGH) .curve(b) is valid when MUTE=HIGH(Contek TEA1062 is LOW) and the receiving amplifier is
driven;Vo(rms)=150mV,R L=150W.The supply possibilities can be increased simply by setting the voltage drop
over the circuit VLN to a high value by means of resistor RVA connected between REG and SLPE.
