TOPPING PA3S Power Amplifier 2xMA12070 Fully Balanced Class D Amplifier 80W*2 ¡¾2¡ÁMA12070 Fully Balanced Class D Amplifier¡¿Each channel of PA3s uses one MA12070 Class D power amplifier chip. This allows separation in layout improving performance and reducing crosstalk. The power is shared across two chips, the heat dissipation is also halved for each chip, improving reliability and extending the lifespan of the product. ¡¾High Output Power¡¿PA3s could output 80¡Á2 at 4ohm load, 10% THD+N. In higher standard of THD+N of 1%, output power will be 65W¡Á2 at 4ohm load. The output power is enough to drive any bookshelf speakers and even some floor speakers. ¡¾Balanced & Single-Ended Inputs¡¿PA3s provides TRS balanced input and RCA single-ended input. The use of balanced input eliminates potential ground loop problems giving the pristinely clean audio without any hum. Two inputs are selectable using front panel button.
