I use it since the beginning of the year, this in several configurations but mainly to feed 2 Sub Dynacord Sub 112. I was already a fan of QSC, very well at the product level. It is true that when we saw the QSC in the 70 and 80 made in the USA, it was the heavy in his hands, but production for China is not unworthy, and then all brands will spend one day either for all or part of the range only the specification and design will be made in the USA. It's really a great product, cheap, reliable, 9 / 10 notes had been max version bridge.
