XH-M543 TPA3116D2 High Power Dual Channel Digital Amplifier Board – 120W

The TPA3116D2 High Power Dual Channel Digital Amplifier Board – 120W is a higher-output Texas Instruments Class D amplifier IC compared to the TPA3110 – same switching architecture, larger output stage. Class D operation keeps efficiency above 85% at typical listening levels, so the board runs warm rather than hot during extended sessions without requiring a large external heatsink. The TPA3116D2 High Power Dual Channel Digital Amplifier Board delivers 60W per channel into standard passive speakers – 120W total across both outputs at a 100 dB signal-to-noise ratio that keeps background noise below what most speakers can reproduce audibly.

The XH-M543 module layout places both speaker output terminals, power input pads, and audio signal input connectors on a single compact PCB. The Xh m543 digital amplifier board rated 60W per channel continuous output is meaningful – the power supply must be sized accordingly. At 24V operation, a supply rated below 5A will sag under heavy output loads, producing distortion before the rated wattage is reached.

Using a properly rated supply at the correct voltage is what separates consistent performance from intermittent clipping during loud passages. The TPA3116D2 XH-M543 connects directly to any line-level source without a preamp stage.The 60 watt amplifier board suits floor-standing speakers, larger bookshelf pairs, and outdoor enclosure builds where the 30W TPA3110 variant leaves insufficient headroom. This xh-m543 tpa3116d2 digital amplifier board available on StemVolt, and uses for building high-power audio systems and DIY speaker amplifier projects.
