TOPPING PA3S Power Amplifier 2xMA12070 Fully Balanced Class D Amplifier 80W*2
【2×MA12070 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.
【High Output Power】PA3s could output 80×2 at 4ohm load, 10% THD+N. In higher standard of THD+N of 1%, output power will be 65W×2 at 4ohm load. 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. 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. PA3s will remember the input selected when it was turned off.
【“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. Everything is just in the right condition.
【D10B Could Be Best USB DAC for PA3s】D10 Balanced can provide high-fidelity USB decoding and TRS balanced output. When used with PA3s, it is equivalent to adding a high-performance USB input to PA3s. This combination is simple and efficient.
