Hi Jim, Matt, Barak,
The Elite is different from the Series boards in that the
motherboard is only the width of the master section - 4 modules. The
channel modules buss thru 4 x 16 way .100 ribbon cables and 8 x 3 way .
156 Molex headers to the patchbay, fader and meter. So pulling modules
is a bit more complicated. However it is not hard to disconnect one or
both sides of the desk in one go by pulling the .100 headers from the
bottom of the motherboard.
Fitting the master modules in the motherboard is a pain and has
been the topic of another recent thread.
Barak, have you done anything with the master
modules? Another thing you could try is to remove the FX return and
Aux master modules (desk will run without them) so you can see how the
stereo master module is fitting in the motherboard. There may be some
Molex pins bent, missing or not making proper contact. Try pushing up
on the motherboard and see if the hum changes or goes away. Also check
to see if the ground strap is bolted to the bottom of the mother board.
Best
Ike

ike, matt hi,
the hum is 50hz(actually 49.7hz).
i pressed all solo's on the ch. it still kept quite.
Audio works on the whole console(mix,busses, direct out, aux)
i didn't check if hum is present on aux section , will do first
thing at morning.
talked with mike and he says there is no other way but recapping the
console inc. master section and then checking if the problem still
appears.
of course that will be the way but its another 4000$ ex labor...
what do you think?

Hi
You still haven't said if it is 50Hz or 100. (60 or 120). That
would tell us if it is a faulty power supply or something to do
with the wiring.
The solo bus has a lot less 'gain' than the others unless you
operate all the solos at once.

hi ike,
i have checked if the hum was caused due to external induction...
not. i moved the console 50m away, got the same problem.
i also checked and it seems that the hum is present on mix bus and
on the group out busses but is not present on the solo bus??
so this means there is current running on the chassis. i wrote a
help request to mike s. and i hope i'll solve it asap.
i have a wooden cover i tried covering with metal, still no effect.

Hi Barak,
Is the bottom cover wood or metal? If it's wood, it will make no
difference, if metal, it may help to mount it.
