Thread Starter |  ada8000 serious 50 Hz hum ... hi, Got a 2nd hand ADA8000 (bad idea to have it 2nd hand you may say) I got serious 50hz hum on it ... changed my IEC plug power it from other place in the room (to prevent earth loops). even with the gain at mini I get -57 dbfs of noise on channel 6 (16 on the RME mixer) !!! note that the other channel are not even also ... Any tricks to get rid of that, appart from door step ? Cheers Gilles |

 | I have seen this with those units... Does it go away after the unit has warmed up? (about 20 minutes or so) |

| uninterrupted power supply. it conditions the power and regulates voltage and is a backup. |

| Lives for gear  | like a ford, they write the problem on the front sorry, but that *could* be the problem. These units are well known for being a great bang for the buck deal, but never have a I heard of one being described as quiet. I think you might want to look into external pres/power conditioner/x hum. |

| I had one of those units for a couple years and it did the same thing... I never could figure it out... it just got worse but for me it started on one channel and leaked its way into all the channels eventually. I still have it sitting on a shelf, if anybody has an answer about what it is... feel free to chime in! |
