Noisy Mackie 1604 in mobile home

[musical1too]

This is the first time I've run into this. I play gigs using my Mackie
1604 VLZ and my sound system is quiet and performs as one would
expect. But I moved to a mobile home and now the board is noisy and
hums when set up in the mobile home. I'm trying swapping cables and
using ground lifts, and have had an electrician out to look at things
but nothing seems to help. Does anyone else have experience getting
clean sound while living in a mobile home? Thanks for any insights.

Is other equipment, not connected to the Mackie, also noisy?

Have you checked that the power (Safety) ground is good and the mobile
home wiring is sound and correctly polarised at *all* the sockets you use?

Given those, the way to get stuff quiet is exactly the same as in a
building. By making sure the rules are followed and the ground
connection is good, I've had good sound in a motorhome before now
without using special tricks.

It's possible that something got damaged in the move. But it could also
be that your mobile home doesn't have as good a ground system as other
places where you have set up. There may also be nearby sources of EMI
that are causing your problems.

While it might not be the ultimate solution, you might see if you can
arrange
for the loan of one of those balanced power systems to see if that gets
rid of your noises. It's rather a broad stroke, but can help you to
narrow down
the possibilities if it works.

What is plugged into the Mackie?

Do you get the noise if you disconnect everything and just have headphones
plugged into it?

Does it happen all the time or just at certain times of day?

"Noise" and "hum" are generally thought of as two different things.
Are you hearing BOTH "noise" (like hiss, popcorn, etc.) AND
"hum" (50 or 60Hz from the power mains)?

But what does it sound like with NO cables at all? (Only your
headphones listening to the mixer)? You didn't mention what the
mixer is connected TO, so we are working in the dark here.

What does "look at things" mean? Does that mean that the electrician
checked all the outlets for proper wiring (hot, neutral and ground)?

There shouldn't be anything fundamentally different about operating
equipment in a mobile home assuming that the mains power wiring
is connected properly.

So what IS different about this location? Are you at the far end of a
power feed serving rather more people than it really should? Are
industrial premises sharing the feed? Are you under power lines (or
is this a high-class mobile home location? :-).

But first answer my question about other gear. This is a Mackie 1604
after all. Great little boxes until the ribbon cables give up.
perhaps that's starting.

How about very near a radio or tv transmitter?
