The Topping PA3 is a compact stereo amplifier that comes with ST’s class-D TDA7498E amp chip. It delivers 80 watts per channel at a 4-ohm load, which is enough to drive 10-inch speakers. LEDs on the front panel indicate the input status and the MCU monitors issues like overload, overheating, and high/low voltage. Two RCA inputs allow you to connect two devices at a time and switch between the inputs using the button on the front panel. Finally, the PA3 comes with ALPS potentiometer, EPCOS film capacitors, a Nichicon hi-fi capacitor, and an OMRON relay.
