Ground loop issue, snipped cable screen connections to pin 1 now monitor pops loud when turned off

Postby zakduff » Sun Oct 25, 2020 2:31 pm

I had a ground loop issue so i found a few posts on here which instructed the following:

“At the speaker ends of both balanced cables, open the connectors and snip out the cable screen connections (to the sleeve or pin 1). “

I have done this and it has resolved my issue and no longer have a buzzing sound however when I turn off my studio monitor it pops loudly. Obviously I’m turning my (powered) studio monitors off first and my volume is down on my audio interface but it still pops really loudly.

Any advice will be appreciated

Update:

Not sure what was causing it but it’s not happening anymore

I did have another XLR cable plugged in to my other monitor which I hadn’t altered yet.

I also did turn it off only about 10 seconds after powering it on.

Guessing it was one of these two factors that was causing it to pop?

But hey ho, its OK now :)

Hi zakduff, and welcome to the SOS Forums! 8-)

Glad to hear you've solved your problem, but if anyone else wants more info on possible XLR pin 1 ground loop problems, have a read of my Q&A here:

Hi Hugh,

Late update but when i’ve just turned my studio monitor on its caused a loud pop similar to that time i turned it off.

It was the same monitor (right) as last time, any ideas? :)

Could be myriad reasons. I wouldn't be concerned u less it becomes a regular thing.

Hi Hugh,

Admittedly I hadn’t turned my monitors on since uploading this post

I have just filmed turning them on and right monitor popped again and then the left monitor started buzzing

Have you checked that the monitors are actually grounded? Do they have a 3 core power cable? Has the power wiring in your studio been checked recently?

Yes, yes and no :D

What checks would that be specifically?

If you are in the UK I'd suggest one of the socket testers with three lights on them like the one at
