I encountered a weird problem on my Nomad. One morning, I wasn't able to get a decent level out of input 2. Even with trim and fader maxed out, I was barely able to get enough level to work with. I was testing with my voice, yelling progressively louder and louder in the mic, and I could see the level going up, and when it was getting close to -8dbfs, the signal was suddenly going very loud and distorted. I tried different cables and mics, same problem. I finished the shoot without using this input, and I performed my regular maintenance on it this morning. I started by opening the Nomad to change the internal battery, I did a factory reset, I updated the firmware, and then I performed the trim calibration procedure. Everything went back to normal for about an hour, and then suddenly, the levels went super low again. I performed trim calibration a second time, but this time I couldn't see the levels "creeping up" during calibration on input 2. When calibration was over, I was able to get a normal level of signal in input 2, but now the preamp is VERY noisy. I hear a very annoying buzz that wasn't there before. My guess is that the calibration was performed when the input experienced the "low level" problem and it compensated by maxing out the trim setting. That's why I can hear the noise from the preamp now. I also guess that by some chance, I "fixed" the problem before the first calibration, either by updating the firmware, or by opening the Nomad. My nomad is now read to ship for repair, but I'm still posting here to see if anyone ever had this problem. I'm also curious on what I did the first time that seemed to have fixed it for an hour!
