Default Re: C25 ethernet noise?

On several cases in which noise has been detected when ethernet activity
(faders, VUmeters, etc) the solution has been to double check grounds on every
connector. This includes the amplifier audio cables, and speaker cables. If this
connection is not balanced, then the "-" has to be grounded.

On other cases, when the power amplifiers and the Control 24 are plugged into
different power outlets, this will result in a constant hum or buzz.
Disconnecting the ground pin at one end of the audio cable feeding each power
amp should break the loop.

Similarly, if you are connecting a syntheziser or a guitar on the "DI" input
with a mono cable, make sure you are using an unbalanced mono cable. If you use
a balanced stereo plug or "TRS" then the "-" pin will float and will pick up
noise.

Hope this helps you solve instalation problems. If problems persist find your
local shaman for the "Mother Earth Dance"
