48V Phantom Power??

I have a Behringer PMH3000 which has 8 XLR usable channels. I have 6 of these taken up by regular XLR Mics, and I want to add 2 Condensor Mics that require 48V Phantom Power to run on 7 & 8. If I turn on the 48V on the mixer to supply power to these 2 Condensor Mics, will this effect the other mics? Thanks.

Unless you have a ribbon mic or some antique dynamic mics, it won't be a problem. Modern mics that don't require phantom power are wired to ignore it if its turned on.

i used a yamaha o2r desk at college, which has individual PP switches for each channel and our tutors use to freak out if we left the phantom on by accident while using a dynamic mics. lol use to ask if it was dangerous or damaging to the mics, why do the majority of desks have single phantom switches? they never did answer me.

one of them even reckoned they were electricuted by a microphone while singing live due to this reason. any one ever heard if that happening to anyone? i find it a little hard to believe unless the mic had wiring problems of some kind.

The condenser mic has the same chance of shocking you as a regular dynamic does. It is as you stated usually a case of bad grounding somewhere or faulty wiring in the mic itself.

Keith Relf, guitarist for the Yardbirds, died as a result of improper grounding. It's a real hazard. Always wear shoes when playing outdoors.
