Hey guys, this is sort of a combo question, but I guess this is the right place to post. First of all, I have a GK MB112, and I seem to be getting no output from the DI out. I have tried this from the MB directly to a mixing desk and also directly to a PA amp, but nothing. I have yet to open this to see if there is a wiring fault (are these wired or straight to the board?) as it is only 4 months old, but I bought this amp in Italy, and I currently have it in Spain, so I can't just take it back to the store under guarantee. Anyone know if these have a European/Worldwide guarantee, or do I need to return to the place of purchase? Secondly, I have an active/passive DI, but for some reason, the output of this (even in active mode) is not powerful enough to drive a QSC amp without going through a mixing desk first. Is this common?? Thanks in advance for your help, as always!!!
