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.

Guitar --> pedals --> Acoustic Image Clarus --> A&H Mixer --> Peavey Power head

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.

Ok here we go.. I've had this issue for awhile now and I'm finally getting super annoyed with it.

I have a Mackie mixer (profx12) and I have 4 QSC K12 speakers. I use these at my temple as our sound system. I have the mixer in the sound booth and the speakers outside the sound booth. I am running two XLR cables out of the booth from the mixer to the speakers. I use one XLR cable for two speakers.

Hey guys,

Really need some help with this. Hope you've got some time to help me work through this because I couldn't find too specific of information about it on the web for my situation.

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.

Hey everyone! I've got a problem and it seems so basic, but I can't solve it. I'm using Pro Tools to record my acoustic guitar. I have an mbox mini as a USB interface. When I plug the guitar into the MBox, I get this low ringing, electronic sounding buzz.

I am reconfiguring an extremely modest studio (A DAW with Cubase LE4, respectable monitoring, a few mics, and a couple of rack units like compressor, preamps etc).

I understand that it is desirable to have everything powered from one outlet to avoid ground loops, but sometimes that is impractical.

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.
