2 x 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 80W x2 at 4ohm load, 10% THD+N. In a higher standard of THD+N of 1%, the output power will … Continue reading TOPPING PA3s Balanced AMP
