Review on 🔊 12V Amplifier Board - DROK 15W+15W 2.0 Dual Channel Digital Stereo Audio Amplifier Board PAM8620 DC 8-26V 24V, Mini Power Amplify Circuit for DIY Sound System Speaker by Rashad Ross

This is for the 15+15 version, not the smaller ones. I hooked it up to a 12v power supply and some old PSB floorstanding speakers. It gets along very well with the speakers. However! The "Differential Audio Input" is very noisy even when using a ground loop isolator. I was planning on using RCA/differential inputs but there was plenty of that and other stuff even with the jumpers removed. Using the 3.5mm input was ideal though, and even at the lowest volume there's not much (if any) background hiss or hiss. So minus one star for the useless RCA inputs (they aren't true "balanced" or "differential" audio inputs because balanced audio has three jacks per channel instead of two like RCA jacks), but plus four stars for what they do are so great . in such a small package.
