Works like a hot damn! Powering a pair of big old JBL speakers. No hum or noise. Definitely loud enough for me. https://www.st.com/resource/en/datasheet/tda7492.pdf I used both a 15.5V then a 21 V analogue supply. The graphs show that the 21 V should give almost 3 dB higher output and it definitely was louder. As you can see from the chip data sheet it works better with supply voltage near 24 volts -- and if you keep it well below max power THD+N is 0.05%. Remember a “wall wart” supply WILL NOT PROVIDE SUFFICIENT CURRENT. This device can deliver 100 W so you need a supply that will deliver (100 W / amplifier efficiency), at the very minimum. I feed it music from my tablet via Bluetooth. Keep the amplifier board away from your WiFi router as the strong WiFi could de-sense the Bluetooth module on the board and you will lose range.
