Well, a power supply section, either sub-standard caps or the aforementioned DC-to-DC converter, would definitely explain something like this, as these issues can indeed temporarilly go away after the PS section’s spent enough time charging up that the voltage sags are no longer occurring. Lousy caps can cause a bunch of other issues, too, so the DC-to-DC just not bringing the voltage up enough is way more specific to the issue that’s been described and makes sense for this case.
20 years later and InMusic is still having power supply issues on their standalone players. Deja Vu the Numark Axis 8s.
My immediate questions:
Are these just a bad batch of recent DC-to-DC converters or all SC5000Ms affected?
Regardless of the first question, does it only affect certain nations’ voltages?
Tentatively, it looks like there’s a couple people above in 120V countries, and at least one person with one unit that’s having this problem and another unit that’s not.
Has anyone who has the issue now definitely never had issues until just recently, or has everyone afflicted had this issue they think from the beginning and perhaps just didn’t notice it early on?
I can’t help but wonder if the voltage step up issue might have been the root cause for the early M motor speed up bug that they later put in some software mitigation for the motor controller.
Edit:
Neither of my Ms do this during the first 10 minutes of operation, so considering that, a few of the above 120 volt people, and the guy with one unit doing it and his other not, I’m leaning towards some people are getting substandard DC-to-DC converters and/or they’re eventually going bad, and that this might affect all standard input voltages. I should also note that I was an early adopter of the Ms. So maybe it’s just certain production lots affected. I did take a year off from using them and perhaps didn’t use them as much as other people did even before that, so perhaps mine just haven’t been worn as much.
Interestingly, everyone with the issue that’s posted pics or videos, which now includes two other threads, seem to have their gear right up against each other. I can’t help but wonder if the failing DC-to-DC voltage step up converters that are causing this might be cooking from poor ventilation. Anyone with the issue now always ensured some significant space around their Ms on all sides like I do?
