A Hum

 Coolness: 93140 | sO,
Since my most recent move, i now seem to be sending a hum to my amp through my mixer... after all of the general trouble shooting tests and cord replacements I could think of, i have isolated the source.... my computer? I'm using gold rca to feed for an input and output from my internal audiophile 2496 (m-audio) straight from my puter to my mixer and I'm getting a hum from both feeds.... I can only assume that its a grounding issue, but i was under the impression that all desktops are grounded?? Could it mean maybe that my soundcard is loose? Any one here have any ideas?? uFOT-hum sound is a terrible thing |

 Coolness: 685630 | I think it could have to do with them not being grounded at the same source; have your amp plugged into the same wall outlet as the computer.. |

| Coolness: 93140 | just tried that, it didnt make a difference :(
I checked a lot of forums thus far, no ones seems to think that its a computer grounding issue, some people suggest that the internal card may be loose, some said to try adding a rubber bushing to the screw connecting the card? UFot-wat tha fak, i hate hum |

 Coolness: 91430 | Might seem silly but try to hook up a long grounded extension cord to one of you kitchen outlet. Kitchens are always grounded. |

| Coolness: 93140 | i dunno, its just so puzzling... all I can imagine it that maybe the power my puter is on is faulty? Thereby sending excess current or run of, which is in turn then picked up and sent by the rca from my internal sound card? I will try replacing the power bar first.
Ufot-damn hum, go away! |

 Coolness: 153045 | i think its the grounding in your place, get a power bar with an "grounding meter light" you will see if the plugs are really grounded, sometimes if your are in old blocks, the electricity is so shitty that the plugs arent even grounded!
... (like my place, right now) (booohooo) |

 Coolness: 106155 | Sounds like a ground loop.
Plug everything to the same power bar and lift the ground with one of those cheap canadian tire ground lifts. ...should solve your problem. |

| Coolness: 153045 | yeah, something like that.
id suggest to get a good powerbar, with light indicators, not a "dollarama" one, there are one made for computers, that what i got and never had any problems |

| Coolness: 93140 | Thanks a lot guys, I appreciate the help... after hours of deliberation, testing, cord replacements... I even switched my sound card to a different slot, finally, I plugged my amp (sans power bar) and my puter in the same socket and the hum vanished... To me it is definitely because the plugs are not properly grounded, so frustrating, either way, as long as the hum is gone for now, thats all that matters...
The place I moved into is a grey stone building (heritage), so behind the shitty plaster and concrete, I can only imagine the snake nests... though all the plugs are modern and the place is newly renovated, I have a feeling the electrical work was bunk at best... anywy else ever wonder why plugs get installed upsidown?? Ufot-hum dee dum gone! |
