*lots of complaints about unwanted hum and noise with the MN busboards.

isn't this a PAST issue ??
with the first shared system

i thought this was fixed ?
i spoke with tony , when he was in Montreal last summer
and he seemed aware of the problem with older busboards
i think it has more to due with running the power supply to close to i't limit

i have picked up a used SS
it was one of the first generations and it was unusable for live use (hum and noise)

the shared system was redesigned since then
the one i tried at MOOG AUDIO with ROSIE was very quiet in the headphones and on the PA

you should contact MAKE NOISE directly and ask TONY about the issue.
