So last Saturday I forgot to pack the QC power supply for my gig, I did arrive at the venue and the only thing available was the little 1spot charger I normally use for my Shure wireless. So I just tried it.
I knew 9v wasn’t gonna ruin the unit but I also thought that it might not had enough juice to get over booting up.
To my surprise the QC powered up with no problems.
The only downside was that the output volume was significantly lower. The sound engineer told me he had to give me a 41db boost, but he also said that there was no significant noise so he had no problem with it.
I thought that some of my more complicated presets would not work, but everything has run smoothly.
@Avelon Just looked it up; seems to be 1700mA (1,7A), so withing the experimental testing limits posted somewhere in here, but I can’t find the related thread again.
Yes the power supply says max 1.7A, I remember someone mentioning that someone at neural had powered the QC with a one spot. but I was honestly surprised by the low level of noise
That’s pretty surprising. You wouldn’t want to do it long-term as starving a device of voltage drives up amperage draw and can cause key components to run hot. Glad you made it through the gig, though.
That is good to know, and yes not a long term fix just a quick fix to get through a gig. The alternative would have been to do the whole gig with my strat directly DI to the desk. As at the same time I left my POD express in another case and that is usually my backup.
The 1.7A max output of the OneSpot is slightly less than the max current draw that I found in my testing of QC’s current draw. The highest draw I found was 1.76A (during bootup) so it’s really close but the QC does definitely draw more than 1.7A. However since it did boot up with the OneSpot it should be good after that since the highest draw I could generate during actual usage was 1.4A. I think I need to rerun the test under CorOS 4.0.1 to see if anything has changed. Here is the link to my post about the current draw of the QC:
