I think I was not the only one who thought so. You can understand what is fed from the PC, about the lace in the kit.

And who said that USB is a computer port? Maybe this is a PSU connector? And 2 amperes is with terrible distortions, so no one will listen. Even with standard 10%, the current is less than 1.5 A. And with 10%, too, a normal person will not listen.

But nothing that is limited to a current of 500mA. And the pam in the load eats up to 2 amperes. What we get is either burning usb or limiting the power of the amplifier.

Why is the word "active" in the title? What electronic amplifier can be passive?
