Touching un-terminated and un-connected high-impedance audio input leads will often pick up mains hum. this is perfectly normal.
If it's still picking up hum when plugged into equipment, then you have indeed got a problem. Usually it's a ground loop problem or even poor screening.
A power conditioner is always a good idea anyway, it stops spikes and brown-outs, but won't necessarily stop hum pick-up.
kind of obvious thing of advise here: are your audio cables 90 degress to or parallel with power supply? preamps can pick up ground noise if your wires aren't "neat"
anyways, consumers won't notice this or care when you mix down. we audio engineers fret a little too much lol
is it pci card bleedover noise? noisy preamps? would a humx or he2 by ebtech help? or do those only help on the way out to monitor speakers? i think relying on noise reduction plugins is bad bad because it likely hurts the sound quality on some level....
what about the power conditioner?power conditioners have EMI/RFI filters...know whether the $300 ones have better filters than the $20 power strip/surge protectors that say they have emi/rgi filters too?
did the power conditioner work....have you heard of the 3 to 2 prong ground lift thing (warning that is supposed to be quite dangerous relectricity wise and not recommended, but it involves that 99 cent adapter things you can get at walmart) . you seem to have proved its not some hum being introduced on the way to the monitor speakers, but something introduced on the way in to your
The Furman won't really help matters that much, as it's probably more an issue of grounding within your home. I have this problem with my setup as well, so I'll hopefully get a dedicated line AND some rf/ir filtering device once I get the money saved up. To complicate matters, it could be your computer causing that noise, as it's PCI based and sometimes you'll hear interference as a result of that. Hopefully you've figured out your issues. :)
Mine does the same thing, but not to the same degree as yours. When my mic is plugged in it does not do it. I get no audible noise other than a little hiss at full gain with the mic unplugged. I also get noise when I roll the pots but it goes away right away. I,m pretty sure it's a 60 hz problem, I have a dedicated line to my studio maybe why mine is not as bad. Good luck man.
I had the Emu 1820 and Now I have the Emu 1616M. First of all thats normal with preamps for that price range.Thats the battle trying to record the hottest signal with out overloading and picking up ground noise.I do have the monster power pro 3500 and yes it will improve your audio quality. Alot of floor noise is from your bad power. Every house has bad power cause you got several appliances on the same power.Protect your gear and get a power conditioner and invest in a good preamp.

Looks like your using adobe audition.. Use the noise reduction plugin to get rid of the noise when your mixing down

Great review. As "eighttracks" said, get a nice preamp and a "power conditioner".
OR.. ;)
Try izotope, awsome app for removing noises. Izotope can learn your audiotracks noise and remove it. Pretty cool ;)
