Protected Mode for Electronics

[radiooff]

Hey all,

I got moOde 7.0.1 up and running over the weekend. And I'd finally had the time hook up my USB DAC to the moOde Pi. Well, I went to power up my Topping D50S and the LCD said "Protect". I thought that ain't good but I could not figure out what had happened.

Well, the low-noise DC power supply I bought was 12V not 5V. Oops. I contacted Topping and they said hook it up to USB and see. I got the reply today at work. My replacement 5V power supply just arrived at home. I was hoping the Topping reply would have been a bit more in depth. Like say, "Oh yes, there's an over-voltage circuit that cuts power in these cases."

So, in general, do electronics that can display at protection status usually has a feature to prevent damage. Or could it just be, "Hey, you're f'ed." I've googled to see if this unit has such protection. I can find protections like this on other DACs, but nothing mentioned specifically on the D50S. I am wondering if I should return the unit or keep it if it does work?

What say you?

I think you need to establish whether it works or not, the protect message would indicate hopefully that it recognised the higher voltage.
I'm not sure of the rationale in returning it if it works?  If it works as before I would keep it certainly.

Thanks, I am going to test it in a little bit.
