One issue though, I'm getting a nasty zipper
noise in one monitor
connected to the edirol ua-25 whenever any keyboard, trackpad, disk or
video activity happens. If I unplug from the power supply and run on
battery the noise goes away. Everything (laptop and 2 active monitors)
are on the same power strip. ua-25 and remote25 are usb powered. I
recall someone else reporting something similar recently.
Is there anything I can try to do to get rid of the noise when plugged
into power?
I doubt it - it sounds like your laptop vendor used cheap noisy
capacitors.
If you use high-end power strips with over-voltage protection like
from APX or other vendors then possibly putting them on separate power
strips might work.
