I have Sony wireless headphones that I put in all the connectors to use with the PreSonsus AudioBox 1one. I get a hum from the preamp no matter what I do. I have replaced/changed the cables connecting the headphone to the preamp, but I still get the hum.
I am using an HP laptop, studio4 software. Interesting, when I unplugged the computer's main power supply, the humming actually got louder!
Is there any quick fix to this? Do I need another set of headphones? Is there a problem with the grounding of the system? It's very annoying.
I am simply recording speeches and do not do any of the sound editing.
