I am not totally sure if it was a complete failure yet but I think so. Josh of course greeted me like he knew me forever and invited me to make my self at home and get comfortable. Any how, hot show but I never ran sound board into my UA5>NJB3 before and was using the back rca inputs in and optical out to my NJB3 w/ the XLR cables still plugged into front (Forgot to unplug) but phantam power off. I am not sure why I could not see levels on my NJB3 even though I cranked up the little knob in back past 3 o'clock. Tonight I am going to check out why it failed if it was a complete failure or not. I am pretty sure I got no signal goin' into NJB3 but was not sure why because when I saw that I tried a SDIf rca cable and I changed the input Digital/anolog also I played w/ moniter on and off. Still no clue.
