🔊 WINGONEER TDA7492 Wireless Bluetooth 4.0 250W 2-Channel Audio Receiver Amplifier Board Module Review

Pros: low cost, lots of power, clear sound, accurate playback, compact size, choice of bluetooth or aux input, bluetooth maintains a stable connection anywhere in my 1100 square feet. Feet, Bluetooth installation and connection are reliable. Cons: Must be handy, doesn't come with power adapter or case. Weak noise (probably due to the fact that the PSU is in close proximity). I used a 19.5V 3A universal power supply with a 2.1mm DC plug. I connected this amp to Pioneer A SP-BS22-LR Andrew Jones…

The good news is that Bluetooth works and is completely…

I got what I expected. I knew it would be overrated. I knew there would be other downsides. I first put this amp through some subjective testing with two 4 ohm speakers and several different input voltages. I then used a very expensive Audio Precision unit to accurately measure the power output, signal to noise ratio and frequency response. I also noticed some oddities, so let's get on with it all. 1) It's a far cry from 50Wx2 @ 10% THD as advertised. Even with the lowest gain setting (of the 4
