The reviews on Musicians Friend give some suggestions on how to work around the hum. One suggestion was that the phantom power on the pre conflicted with the phantom power on the main mixer. Another suggested putting something in between the pre-amp and the mixer (like FX unit or similar). Another suggested using condensor mikes only. People complaining about the lack of a ground loop is pretty consistent, though.

Hi folks,
This is related to recording, and my recordings are made on linux, so,
it is tangential to all of these lists. :-)
I own an ART tube pac, which is a preamp compressor combo unit.
It is the first generation of this unit I believe. I've just started
using this unit.
Anyway, I'm hearing a low level hum, sortof like a grounding hum.
Does anyone else use the ART line of pres? Has anyone had trouble with them?
The unit uses 2 tubes and I'm sure they aren't high quality tubes.
Could a lower quality tube cause a low level ground hum?
The unit has a grounded plug, and I can't seem to get rid of the hum
by unplugging other components, but when I mute the unit through my
sound card, the hum is decreased. The hum is audible in silences on
my tracks, so I know it's not just my playback system.
Now, before you go on about how the ART pre is cheap and crappy. I
know it's a budget pre, that's why I can afford it. I'm only looking
for constructive ideas, or similar experience.
Thanks so much!
Rusty
