Ground-Lift for Laptop

Hey,

I'm currently a technical manager in a theatre and I was advised that I buy a ground lift for one of the stereo inputs on our desk which is generally fed from a laptop with cuing software as a slight buzz can be heard when a laptop is charging.

I did a slight bit of research and all I could find was people saying that there's no way a laptop would require a ground lift whilst others argued otherwise; none actually suggested an item.

Anyhow, any ideas?

i have never heard of a ground lift being needed for computer either. are you getting unwanted noise*? is all the equipment being plugged into the same outlet?

edit: i see you're getting noise when the laptop charges... dunno if a ground lift is gonna help ya. i was worried more about the other equipment. most people won't notice 'a little noise'

No it's not all plugged into the same outlet. One other thing that was mentioned was our induction loop, I can't remember what was said about it though...

What you most likely need is this:



Does it make extra noise when you move the mouse and such? I had issues with noise on my laptop, as did another UGer a whie back, and this solved the issue. I have no clue why, as I'm no electrician, but it works.
