I’ve done quite a lot of searching and testing myself and am 99% sure it’s a hardware fault that’s developed but I was wondering if anyone here might be able to help me out:
I own a UR824 which until very recently was working perfectly. Input channels 5 and 6 were being used for a stereo synth, panned left and right respectively. I frequently use my UR824 in a direct monitoring situation with the monitors plugged into the first set of output pairs and a rough mix set up through the dspMixFX utility. I came to play my synthesizers last night and found that no signal was coming out of the left monitor for the Korg Modwave I have plugged into channels 5 and 6. On looking at the UR824 I could see no signal input light on channel 5 when there was the corresponding light on channel 6.
Of course my first worry was a loose cable / problem with the synth. I checked everything and to cut a long story short, different cables, different synths - nothing seemed to give any signal in input 5. Now of course I was worried that it was a hardware fault with the UR824. Seeing as no computer was involved and all the other channels were still working, I could rule out a software issue. I tried turning the pot for input 5 all the way up with the pad off and suddenly signal came through, albeit horribly distorted and cutting in and out (I’ve attached a video to demonstrate this all). The Modwave is connected to the UR824 via two balanced TRS cables and has worked in this configuration for a good while… Would I be right in thinking that there’s likely a faulty analogue component on input 5?
