hey gang,
i've read a lot of conflicting threads about how turning phantom power on and off at different points in the setup process can damage mics--both dynamic and condenser. i can't find a thread that's dedicated to the subject, so i thought i'd start one.
my process is to connect all mics with the power off the mixing board, then turn on the mixing board, then the phantom power, then the power amp stage if i'm using a PA. this way there aren't any audible pops. not sure if this is a bad idea, but i don't see how it could harm anything.
supplementally i wanted to present a problem and see if anyone could help me diagnose it: i have a sennheiser e865 which seems to be malfunctioning--occasionally the high end seems to fade in and out, and when it's faded out it sometimes snaps back in with a soft plosive. it sounds like a wide low-pass filter is on. i've tried different channels on the mixer and they all work the same. the only other mic i have to play with is an sm58, and it sounds like that all the time, so it's hard to tell--it could maybe be the mixer.
i always follow the power setup i described above, but sometimes when other band members set up they've turned on the mixer with phantom power on already and turned it all off at once. can this kind of thing damage a condenser? would it have this kind of effect?
to sum up: what's the best way to set up a live rig with phantom power, and what are the potential hazards of setting it up incorrectly?
thanks!
