Guys,
We're installing our audio gear in London and on first power up the
gear is humming like a demon. We were able to test our signal in the
US before ****pping only as far as the amplifiers because they came
hard-wired for 240V, and it was clean up to that point. We are
connected to the building through rack power strips with appropriate
UK plugs. The building is undergoing renovation so anything could be
at work.
It sounds like a typical bad ground condition, so I'm asking for those
with experience in this realm to lend ideas on how to overcome this
situation without lifting grounds, or a suitable testing means that
would say the problem is the building ground itself. We've got
computers involved and don't want to lose ground (earth).
Thanks ever so,
LJ
