I just bought a set of powered monitors - SP-8B's. My first proper monitors... They sound great. However, I notice a low hum in both speaker cabinets when no sound is going through them. Is this normal with powered monitors (sound of the transformers or something?) - or is it something to be worried about?

no, your monitors ahould be as well as a mouse. :)

what are they connected to?

may be a ground loop issue.....
 
I have some new sp8bs. They are dead quiet. Have em hooked up with the unbalanced RCA outputs from my CD recorder. Sounds like an electrical problem to me.
 
Try hooking them up to another source - something self contained like a tape deck or CD player - where the monitors and source are both plugged into the same outlet strip. Let us know if they still hum.

Looks like I may well have a ground loop problem. My guitar amp carries the same hum, though a bit louder - doesn't matter where I plug things in throughout the house.

From my research on the web, looks like my next move is to try and isolate the problem. I'm thinking that I'll shut off all the breakers at our breaker box and start turning things back on one by one until I find the problem.

Anyone else done this?

I have everything in my recording room isolated on one 20A circuit.

I have a bad ground loop problem when I hook my console up to my computer to dump tracks. The only way I was able to isolate it was to lift all of the electrical grounds of the entire computer system.

I know this is not recommended, but I only do it when I'm dumping tracks. Afterward the whole system comes down and I remove the ground lifters.

I uploaded several tracks of music to NWR and all but one has that damn ground loop buzz.
