Small But Mighty Amp With 2 RCA Inputs

Ideal for driving bookshelf speakers, the Topping PA3 is a compact power amplifier equipped with ST’s class-D TDA7498E amp chip. It delivers 80 watts per channel at a 4-ohm load—enough to drive 10-inch speakers—and has a curved, screwless front panel design that looks sleek in any setup. Two LEDs indicate the input status, while an MCU monitors issues like overload, overheating, overvoltage, and low voltage. On the rear panel, you’ll find two RCA inputs, which allow you to connect two devices at a time and easily switch between them on the front panel. Additional components include an ALPS potentiometer, EPCOS film capacitors, a Nichicon hi-fi capacitor, and an OMRON relay.

Note: At checkout, you’ll have your choice of color: black or silver.
