Topping PA3s, balanced and powerful

The Topping PA3s is a compact, balanced and powerful class D amplifier.

It features two Infineon MA12070 chips and single-ended balanced connections and superb performance for your headphones.

Class D balanced amplifier

The PA3s is based on a pair of Infineon Merus MA12070 class D amplifier chips to develop 2x65W power below 4Ω or 2x37W below 8Ω with high efficiency.

This balanced architecture, with one chip per channel, significantly reduces crosstalk with precise level restitution. Here, heat is dissipated by a radiator covering the two amplifier chips.

Adapted to all

The Topping PA3s has dual inputs to suit all needs and systems.

There is a single-ended stereo RCA input and a dual balanced 6.35mm TRS jack input. The use of these inputs eliminates any possible looping problems to provide a clear sound.

All inputs can be selected directly from the front panel button.
