Any way to stop this? I've replaced my cables with higher quality ones, etc., but it seems like the speakers themselves are picking up the signal. (That is, I don't think it's my other hardware, like my 828, because even turning the volume down all the way doesn't change the noise.) As you can imagine, it's hard to monitor very clearly with all the radio interference. Any ideas? Thanks!

i know this was an old post but i know how to at least alleviate the situation if not eliminate it..

as you may know the hum comes from the 60hz current in your power cables and unfortunately all the cables have to run behind everything with the damn power cables. the way to minimize it is arrange the cables so that speaker crosses power at 90 degrees, when they run parallel the interfering current leaks into the line more.

its kind of tricky to arrange it at first but its possible..

The only way I know is to put thin copper sheets and chicken wires on all 4 walls of your room.
May be you can do it with less cost for just only chicken wires.

You may want to go to your hardware store and pickup a small electrical tester.
You can pick them up for 4 or 5 bucks they look like a three prong plug with a couple of LEDs on the other end.
Check all your power outputs if you've got a hot ground or reverse polarity some where can cause this kind of stuff as well.

run all your audio gear out of the same wall plug.
make sure you dont have metal halod lights anywhere near the power you are using. light bulbs on the line suck for that to.
i put in a 20 amp breaker and a single line for all of my gear.
board, monitors, outboard gear, motu 828 mkII, computer.
basicly everything that could pickup a ground loop.
if i get a humm, then it is a cable issue for sure.
all other factors gone.

i had some issues when installing my krks... i solved the problem by getting 3 to 2 prong adapters and then putting electrical tape on the ground ring of the prong... saved my sanity

good point its worth the effort if you have to rewire to keep your studio on a separate circuit.
Florescent lights any where near can do strange things as well.
