phantom power applies to all mike ins??

[zardoz]

I just got my new Behringer MX2004A mixer and am anxious to start recording onto my hard drive via the Terratec 8 channel multi-tracking card I have, along with Cubase 5. I read on a thread that when PHANTOM POWER is switched on that it applies to all mike inputs on the mixer board. Does this adversely effect or damage any mikes that are plugged in that don´t require phantom? Does that mean that if I want to use my two nice condenser mikes that I can´t plug in an SM57, at the same time, for instance?
Basically, I plan to record "live" a session using 8 mikes. The two lead vocals will be using the condensers. The other voices and guitars will be using some cardoid sennheisers that the theatre where we´re recording has. Possible? Dangerous?

no, applying phantom power won't affect your dynamic mics...

but always be extra careful when using phantom power... better don't plug in or out mics when it's on.

also, I think I saw this in my mixer manual, don't plug in instrument jacks when applying phantom power....

Right,plug all your gear in and then turn on the phantom power.

Really? The Behringer puts power on the high Z inputs? That would be a problem.

What happens if you DO plug in a mike while phantom is on? Do you fry out the diaphragm or something? A condenser mike (a Marshall) I have appears to distort at low volume...perhaps for having plugged in while phantom was on? The mike also seems to cut in and out...or is it the new mixer I just got already beginning to act up? Or a bad AC connection to the boards power supply interfwerring with a steady 48V of phantom (a possibility given where I live)? I think the mike cable is OK...at least there aren´t intermittant cuts while manipulating the cable and it´s connectors.

It could be something else in the chain.

In PA applications I haven't had any problems mixing line and loZ inputs with phantom power except for the popping you get when you plug or unplug while phantom power is on. Since that can be damaging to speakers and audiences it's best to turn off the phantom power before switching things around.

zardoz - probably nothing.

it's a better safe than sorry thing.
