Are the outlets isolated? Will this device eliminated ground hum?

Mine does not have this high pitch you're talking about, just a loud hum, rather like a window air-condition unit. Since it is in my basement, it does not bother me. Maybe you have a bad unit?

Ground Lift changes the polarity so if you are experiencing "humming", switch the lift and this should remove any un wanted noise. Coaxial inputs are to plug in an external recording devise. Hope that helps you!

I hear no humming associated with this item. I have purchase two of them ( for home & Beach Condo) and have had no problems.

It's possible they'll help, and they're certainly the cheapest possible fix, but it's unlikely they'll completely take care of the problem. The RF is probably mostly switching noise from the inverter - I'd look at putting an isolation transformer near the AC output of the inverter and shielding the inverter itself as much as you can.

Unfortunately no. I don't know a lot about this stuff, but I understand optical can eliminate hum. Others will be more knowledgeable. I myself would like to know if the annoying hum would be eliminated. Anyone know?

I not totally sure, but I know if there is humming you have some electrical interference. The cables are possibly too close to the conduit in the walls or some other issue. I've had no problems with my setup, but when I turn my microwave on the sub hums. Not a big deal for me since it's not used much. So it's worth a try, if not return it.

I power it on separately. Maybe there is another way to interface them, but haven't discovered it yet. The subwoofer is also separate power, but I guess you could leave it on. I have forgotten to turn it off a couple times with no issues.

I don't know. All I can tell you is that I have a tv, computer, two stereos and dvd player plugged in. If I connect any one of the to another or turn all on at once I get no hum or static. The volume is a little reduced with each button pushed down but no other issues. It shouldn't matter but maybe a shielded cable? I used to have an old computer that produced radio frequency interference. It made static on the older tube type television if it was close to it when I connected cheap audio cable to it.. just throwing that out. Good luck.

In my experience, no. I tried this for the same use. I purchased two of them and tried them in varying places around the cable from one end to another. Surprisingly, I got a little better signal with 2 of them on one cable, but not good enough to be happy. You may want to try one other fix. If you have one of those 2-to-3 prong power adapters that people use to get rid of their ground, sometimes putting one of these on your power strip will completely eliminate buzz. Good luck!

I don't know. I was unhappy with the general sound of the unit and just disconnected it.

not noisy at all and no outlets to the outside. Mine only lasted about 6 months then died. So for me I would not order another one of these

I can't confirm it, but I'm using nearly all the ports and there's no hum coming from my pedals

Is it a ground hum? Because if the speaker has a hum, there is nothing wrong with the speaker itself.

I listened really closely (ear right next to the switch) and too can hear a very faint electrical hum (maybe 60 kHz?). But from any reasonable distance, I can't hear it at all.

not sure exactly, but have you tried using a different cable and/or mic to see if the hum goes away? perhaps one of them is faulty.

Mine have been great! A horrible hum sounds like a power problem. This unit did not come with a power adapter...
