Very strange, my MEC seems to be generating some hum, like 60hz
ground-problems stuff. Even when the thing is unplugged, I still get the
hum. The only time it goes away is when I unplug the audio cables running
from the monitor outs to the mix board. I hate to say it, but the cables
are unbalanced instrument cables. Unplugged from the MEC, but still hooked
into the board there is no hum, plugged back into the MEC -hum. Does this
make sense -even when the power cord from the MEC is unplugged? The only
thing I can think is to get some balanced cables, but if the cables
(unplugged from the MEC) create no hum, will balanced cables solve the
problem? I'm stumped --unless its some energy from the galactic core,
washing over my home town and somehow tuned to the frequency of the MEC -now
that would make at least SOME sense :-)
Thanks for any feedback,
MR
