I'm getting a high pitch noise (attached) that has something to do with the pedals (also attached)
Noise only happens when going through .
No noise when plugging directly into mixer, or into Clarus, then Mixer.

Microphone Ground Loop Problem

Hi, I have a new microphone and it has a electrical buzzing sound when i try to record using it. It is not the soft buzzing sound that can be removed, after searching up about it i realised that it should be the cause of ground loop. So i decided to buy a ground loop insolator for the problem but it still doesnt help. Does anyone have any experience or any idea to solve this?

I wanted to extend my monitors out to another room for a different perspective. So I ran 2 longer cables to the other room, but after hooking them up 1 of the monitors has a hum in it (the other monitor is just fine). I thought it might be something with the 1 cable so I switched the cables to the monitors, but the exact same monitor still hums.

A condition where current circulates in the ground wiring system, due either to the grounds at the end of a length of cable being at different AC potential, or where a video or audio system has multiple paths to ground. Manifests itself usually by varying levels of hum (in audio systems) or as rolling bars in the picture of a video system.

can someone explain how i get rid of the ground loop hum created when i plug my preamp into my interface. i assume this is what i'm experiencing. the preamp is powered by a 2 prong wall wort. the interface is usb bus powered.

i've read that i have to lift the groung from one end of the chain and not the other but i don't know how to do that.
