Hi there I'm afraid I'm struggling to find any answers to help with my issue. Board was working fine however during use all sound stopped outputting, initially, I tried using the jack outputs instead of XLR and this worked for a short while however as of today the jack outputs also give no sound. Inputs seem to light up via xlr on all but last two channels 13-14 / 15-16 where i get no led indication of any input from my mic. As I say No audio out either in analog or firewire modes through any output including headphones, making the desk no completely useless in the studio. From what i read online there seems to a common fault with the units 5v regulators. Do you think this could be the route of my issues? Look forward to your help
