I´m using a UR28M and I´ve just plugged in my studio monitors (Alesis M1 Active 520USB) through Output A (1/L 2/R) with a pair of balanced TRS cables. But the signal on the 1/R is weaker, like it´s panned to the left. I´ve checked the monitors, they´re fine as far as I can tell. If I keep the cables in the UR plugged in but switch the R/L inupt in the monitors the left speaker gets the weak signal, so the problem is definitely in the UR28M. I get the same effect if I switch to Output B or C. And the headphone output on the UR28M is in balance . Does anyone have an idea whats going on here?
