The sound is great. It can also be used with a 19V 2A power supply. A 24V 2A power supply is sufficient for a small room. Pop noise is huge and dangerous. If you do not take measures, the speaker will break. There is no gain adjustment. I made my own input adjustment circuit. It is a dangerous power amplifier for those who cannot make an input adjustment circuit. Grease squeezed out and shorted the terminals. The shavings of the heat sink were not completely removed. The part number of the generator has changed, but it is unknown whether the constants of the peripheral circuits have been adjusted. The inquiry was silenced.
The left and right RCA inputs are incorrect. I have LM2576 instead of TI LM2575. This evaluation board is wrong in various ways.
