For anyone who owns troublesome mics in the 8000 series, best to wait
until Sennheiser tells us what the problem is.
Definitely there IS a known problem and it is repairable, but whether
it is just contacts or not, I don't know.
Jeremiah, I've tried 3 sets of cables, I get periodic fizzing with
all of them, so not that.
I thought maybe it was humidity but in checking my recordings I see
that I got fizzing on a warm, dry and sunny afternoon.
Also, my first noisy pair of 8020s were professionally cleaned under
warranty, but it did not fix the problem.
Ongoing discussion can be found in gearslutz forum in which I am
participating.
cheers,
Vicki Powys
