This has been posted before, but it's far from the worst thing Behringer has done...
A few years ago, they stole Mackie's mixer design, everything about it. Mackie sued and lost, only because they had not secured their patents early enough. The court still acknowledged that Behringer had stolen the designs. The funniest thing was that the manual was exactly the same, down to the misprints!
I've compared a Behringer of that era against a Mackie with the same content going through the same speakers, and it's hilarious how much worse the Behringer sounds. Lower output, more noise, and really cheesy feeling knobs and switches.
Behringer is a brand best avoided...
This is 100% true:
