Hi
You are looking for something 'common' as it adds up when listening to
more stuff on Solo.
It could be supply noise (check with an oscilloscope) or a module which
is seriously noisy or even talkback or slate tone circuitry that has
access to aux busses although may be nominally 'switched off'.
Double check all possible outputs and look for any 'common' circuitry
(the 'block diagram' should get you close). Ultimately, pull modules or
'break up' the mix bussing if it is available on plugs.

Hello, I think this is the way to post here.
I have a 15 year old 40 channel Elan I bought new. It's been very
reliable. It was in a fire 7 years ago. I got it back in commission
after a couple of idle years of storage and cleaning/repairing. It was
recommissioned and has done pretty well, everything works except some
partially working l.e.d. meters.
Lately the master section has a small ripply soundwhen cranked all
the way up without channels turned on. Small annoyance, but
irritating. However when you solo the auxes you get a really intense
version of hiss noise ripply trash, sounds like a combination of
computer interference meets bad caps/junk. As I said it's appeared of
the last few months. Soloing A,B,1,2,3,4, just adds to the crap
incrementally. When using the track busses to pro tools, it's fine ,
goes to pro tools good and quietly.
I recently tested and or replaced all the resistors in the power
supply and recapped the power supply. I also disconnected the Elcos
for everthing except the monitor one to the amps to make sure it
wasn't from another piece of gear.
I still have the trashy sound in auxes. Any suggestions? Any logical
procedure to locate the source of my noise?
thanks , doug
