2408 mk3 noise

Post by sergiosacoto »

Hi!
I’m writing from Ecuador-South America. Mi name is Sergio Sacoto and I have a 2408mk3 with 424e, it has been the main audio interface of my production studio since 2006 and I have never experienced any kind of trouble since recently.
A month ago I noticed a strong hum electric noise coming thru the summing entrance of my Dangerous Music D Box (this is the 2408 analog out 1 to 8 )
I tried al kinds of things to get rid of the noise but I couldn’t find the source of it, finally I connected another audio interface and the noise was gone, is definitely coming from the 2408 mk3.
Do you have any suggestion on what the noise could be? Could it has something to do with the PCI card? I have a 2 x2.4 Quad Core Mac Pro running Mac OS X 10.9.5
Thanks in advice
