    Default Ground Loop Hum with Audio 10 when computer is plugged into power

    So I just got 2 Techs, a mixer, and audio 10 and they are great, but I get this electric buzz/hum resembling that of a ground loop hum. If I go directly from TTs to mixer to speakers it is fine. If I set it up TTs->A10->Mixer->A10/Speakers I get the hum if the A10 is connected to the computer. After more troubleshooting I found out that I lose the hum if my computer is not connected to an outlet. Everything is on the same powerstrip and Techs are modded to not need grounding.

    Anybody have a similar issue and maybe a solution?

    You will need a ground loop isolator.

    One for every cable that outputs from the audio 10?

    So I fixed it by using one of those little addons to the power plug on my lappy to get rid of the ground.

    Got a link for this add on? I too have issues with laptop power causing feedback. A ground loop isolator made the buzzing worse for me.
