Eventually me and owner have discovered what the intermittant noise problem
is with his large mixer. I could never find the reported noise problem on
the bench. Eventually the owner twigged that the problem only occured at 2
venues and not the others. Both have full dimmable stage lighting, but not
audio modulated or sequenced , and what he was reporting as excessive
background hiss static was mains-bourne spike noise from the triacs.
What sort of retro-fit mains filtering for his mixer.?
Internal or external in-line Y/delta + small choke unit, plug-in pulse/surge
protector, or one of the large choke/transformer? types that hi-fi bods use
in the mains feed..
