Hi guys,
I have extremely annoying static noise coming out of the MatrixBrute Ouputs (L+R) when the USB is connected. I can actually "hear" the computer. For example when I drag a window on the display, I can hear static. If I minimize a window, I hear the static, when doublclicking an application, I can hear static (As if I hear the computer's HD working).
I actually had this with the MiniBrute as well so I think this is some sort of grounding issue that I can't seem to locate. anyone else experienced this?
My setup:
MacBook Pro 2011
RME FireFace 400
MatrixBrute outputs connected to the RME FireFace 400 Inputs, USB connected directly to the Macbook pro.
I tried to exclude the issue:
Disconnecting the power chord from the MBP, made the noise even stronger!
Replacing the USB cable - did not change anything.
Replacing the computer: I also have an older PC with the RME drivers installed. I then tried to set everything up using that PC computer, there was much less noise, but still the noise was noticeable.
Eventually my workaround is to connect the MB via MIDI on the RME FIreFace, and use the USB only for making firmware updates etc...
I would love to use the USB instead of MIDI but I can't locate the problematic noise...
Any advise would be appreciated.
Thanks,
Tomer.
