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
