DESCRIPTION
FULLY BALANCED AND HIGH-PERFORMANCE CLASS D AMPLIFIER
Introducing the latest Topping PA3s, a fully balanced Class D power amplifier to bring life to your HiFi speaker setups. Equipped with two independent MA12070 class D power amplifier chips, the Topping PA3s offer impressive power output to drive your bookshelf as well as floor speakers with ease. It has a balanced architecture where users can connect it with Topping’s latest TRS Balanced DAC’s such as D10 Balanced and E50. As a Class D amp, it uses far less power than Class A amps, making it super-efficient.

FEATURING DUAL INDEPENDENT CLASS D POWER AMPLIFIER CHIPS
In the Topping PA3s, each channel is amplified independently by its dual Class D MA12070 power amplifier chips. By separating the audio signals, the PA3s achieves reduced crosstalk and better audio performance. Independent chip for each channel reduces the overall load on each chip and effectively improves the stability and lifespan of the chips. The PA3s being a Class D Amp means it is power-efficient and produces less heat than a Class A amp. That makes it perfect for a discrete bookshelf unit where heat dissipation can be an issue.


AMPLE OUTPUT CAPABILITY TO POWER YOUR BOOKSHELF SPEAKERS
The Topping PA3s is designed to bring the best out of your Bookshelf or Floor speakers by delivering them with ample and clean power. Topping PA3s provides an output power of up to 80Wx2 @ 4ฮฉ with THD+N at 10%. For THD+N 1%, the PA3S churns out 65Wx2 @4ฮฉ. Drive any bookshelf or floor stand speakers with 80Wx2 of power at 4ฮฉ load. The low THD+N value of PA3s is in the range of 1โ20W output, which happens to be the power range commonly used for listening to music. This value sets everything in just the optimum condition of functioning.


OFFERING BALANCED AND SINGLE-ENDED INPUTS FOR CONNECTIVITY
Users can feed the audio signal to the Topping PA3s using both single-ended RCA and Balanced TRS connections. Topping PA3s offers both fully balanced and single-ended inputs so you can connect them to multiple sources. The balanced input option eliminates potential ground loop problems, providing pristine audio without hum. Either TRS or Single Ended input is selectable using the front panel button, and the PA3s will remember the last selected when you turn it on. With an output power of 80W x2 @ 4ฮฉ, the PA3s can drive small to medium speakers.



ENHANCE THE PERFORMANCE WITH TOPPINGS LATEST DACS AND AMPS
Topping PA3S is a balanced power amplifier with TRS input connectors. The PA3s house a TRS input option selectable via a toggle switch on the front. Topping has designed it particularly for their latest E50 and D10 Balanced desktop DAC systems. Both of these DACs have TRS balanced line-out ports. Complete a powerful Desktop HiFi speaker system with the Topping PA3s for exceptional performance. When you need a more comprehensive audio system, a combination of PA3s + DAC + HPA is most efficient.
