HELP!!!! Hissing from Studio 1824c main output

asked Jul 13, 2021 in Studio Series USB Interfaces by mattycartwright (150 points)
I have just received a brand new Studio 1824c and it has an un-bearable hissing from the main outputs into my studio monitors.  I was hoping I could simply unplug my monitors from my other interface into this one, but I haven't been so lucky! I have now used several different cables, changed the position of the plugs, where things are plugged in, everything humanly possible to sort it out and I can't find a single thing to get rid of it.  I plug my monitors back into my other interface and it works absolutely perfectly, no hiss, no nothing.  I also notice that the main L & R channel metres on the front of the interface are flashing constantly with one bar, even though nothing is plugged in or routed to it, it's just turned on!

Is it a fault with PreSonus or are there any fixes?  Thoughts please!

Make sure you're using Balanced TRS cables and not unbalanced TS cables.

Hi. I just bought one & am having the exact same problem. Have you sorted this yet or is it a problem with these units?

I was having the same issue and I changed the sample rate in the universal control from 44 kHz to 48 kHz and that cleared up all the white noise.

I was having this issue also and the answer given by  eahudimac also solved it for me: Switching between 44.1 and 48k sample rate stopped the hiss. The hiss is quite severe and seems to happen randomly when I boot up my computer, which is a bit frustrating, but this solution works for now!
