I have three Behringer mixers (UB502, UB802, UB2222FX) and all of them work flawlessly. I'm convinced that they aren't of inferior quality to Yamaha's, for example. I had another one in the past, the UB1204FX (one I bought from
www.musik-service.de with whom I had a bad purchase experience). When I took the mixer out of the box, I noticed that it had a little problem in the power supply (in the switch). A problem of quality control, for sure. If it had been purchased in Portugal I think it would been changed for a new unit, but the people at
www.musik-service.de simply ignored all my e-mails... I easily solved the problem locally with an additional 20 euros, but decided it would be the last time that I would purchase something from
www.musik-service.de. Mackie, Behringer, Yamaha, they are all made in China, these days.
