Is setting the sensitivity to 10dv bad? With the sensitivity set to 4dbu, the signal is significantly lower. I'll check for attenuated settings on the drum machine, but I haven't made any changes there. Should the drum machine's manual tell me flat out if the output is balanced or unbalanced? The only information I could find is that the output is fixed at 4dbu. From a not so helpful Guitar Center rep, and my own assumptions, I took this to mean that the output is unbalanced. I have the same problem with my keyboard's manual, but it only tells me the output is fixed. An attempt to use balanced cables with the keyboard resulted in an fairly lower volume output. Can you offer any advice regarding this?
