Ground Loop / Hum
Posted: 06 Feb 2019, 13:09
I'm having what I think are two separate issues...
I have a nasty hum coming though my monitors. At first I thought it was my AX8, but at my drummer's house it is dead quiet. I do notice that, if I turn my guitar away from my computer desk, the hum will fade a little. I've read there are all kinds of variables that can create hum, from outlets to computers to monitors (screen not speakers). Where is the best place to start to track this down?
The second problem is a high-pitched whine that is coming from my interface. I've read that the cause is usually because the USB cable is being used to pull power and creating some sort of loop in the PC power. It it time to find an interface with a power supply?
