TOPPING PA3s Balanced Amplifier 80W×80W RCA/TRS Input 2 Channel Class D Amplifier Features： ☑ 2×MA12070 Fully Balanced Class D Amplifier. Each channel of PA3s uses one MA12070 Class D power amplifier chip. ☑ High Output Power. The output power is enough to drive any bookshelf speakers and even some floor speakers. ☑ Balanced & Single-Ended Inputs. PA3s provides TRS balanced input and RCA single-ended input. ☑ “Comfort Zone” with Lowest Distortion. The lowest THD+N of PA3s is in the range of 10-20W output, which happens to be the power range commonly used for listening to music. ☑ With the help of a DAC, the Function is expanded to a greater extent. PA3s can be used with a DAC to expand the categories ofdigital inputs; If used with a DAC + HPA , more comprehen -sive functions can be achieved.
