🔊 Zerone TDA7498 Audio Amplifier Board with Built-in Fan - 2×100W Class D Digital Power Amplifier DIY Circuit Module, Immersion Design, DC 9-34V, Protective Shell Review

This amplifier is a waste of money. The sound quality is average at best and the protective casing is bulky and unattractive. The amplifier runs warm after a few hours of use and the fan is loud and distracting. The only positive aspect of this product is its affordability. However, in the world of electronics, you truly get what you pay for.

The screws for the fan were too short and I had to use others to hold the fan in place, also the right audio connector doesn't work so I only get MONO sound from the left Side. The plexiglass on the lid was not cut properly and the bottom of the lid broke in the process the circuit board is larger than the container which was disassembled and I had to reassemble what is the red switch 1, 2 on and off for?

I would like to start by not being able to test this amplifier and the reason is that it did not come with a manual. Assembly instructions would be nice, but not a must. I'm sure everyone could understand that. The missing instructions are the audio in/out cables. I would suggest that the front side with the potentiometer (volume/gain control) would be the input using standard audio cables and the opposite side with the left and right signals screwed together would be the output. But who knows?
