Main features and benefits Strong and stable power delivery: The main circuit uses SMD electrolytic capacitors with a total of 4 x 470 uF to provide robust power supply and smooth current for continuous operation, reducing ripple and maintaining performance under load. Efficient, quality amplification: Uses the TPA3116 classD amplifier for reliable, efficient audio performance in a compact package. Low noise, clean signal: quality resistors are selected to optimize signaltonoise ratio across the entire device, enhancing overall sound clarity. Durable, well‑built PCB: The PCB is 1.6 mm thick, doublesided sheet metal, with a copper thickness of 2.0 A and a tinsprayed finish to promote good current flow. Firstclass PCB quality. Typical use scenarios Desktop stereo or compact HiFi setup: pair with 48 ohm speakers for clear, efficient amplification in a small living or workspace. DIY audio projects: ideal as the power amp module in custom speaker builds, soundbars, or project enclosures where reliable amplification is needed. Upgrading or replacing: suitable as a replacement amplifier stage in small home theater or multimedia devices that require a compact, efficient power amp.
