3. The power supply current is recommended to be above 2A.
4. The speaker cable should not be too long, and ensure that it is suitable within 1 meter

Chinese Low (price, not the sound quality) Fidelity products steps onto expensive hi-fi world. The sound of this five dollar amp is nothing short of its expensive cousins. I tried this little marvel with an old 12V HardDisk power supply and amazed. The maximum volume was not much with this power supply and tried it with another supply, which was an old 24V, HP printer power supply. And the sound was house filling. At this mode, the amp heated up to higher temperatures. The capacitors could burn fingers. So I lowered the volume. My opinion is the amp, (with the bluetooth) has been sounding very well. But I am suspicious of when will it break down, like many Chinese products. But I hope it will serve a couple of years when I listen at moderate levels. The 12V power supply will be keeping the amp from failure. The picture shows it is on the HP 24V power Unit. I could not figure out, how 3.5 aux and line-out connections works, yet. But it is a good product even it has only bluetooth.
