Topic: short answer will my UA-5 phantom KILL a Sure PG48?

[run_run_run]

I need phantom on the "other" front channel and don't want to wire via the back RCA if I don't need 2?

[run_run_run]

still curious

BUT I made it work

XLR ~> shitty ART pre ~> ghetto cable ~> RCA back on the UA-5

You should be just fine with phantom on that mic

[run_run_run]

Last night we did this for the "demo"

FUCK IT WE'LL DO IT LIVE!!! (you know the source of that "" lol) We had a whole 1/2 gallon of a Dark IPA at 7.5 more beers etc.

2 channel 16 bit (field style with battery power), Card ADK mic'n the acoustic and used the Omni ADK cap for "room / vocals".

And....
How did it come out brah?

[run_run_run]

yeah it works fine with +48

I have seen this more than once...  The sound guy has everything all set up for a show, mostly SM57's and 58's, etc, and someone says "I need phantom power on this DI" and the sound guy hits the 1 button that turns on phantom power for all the XLR channels of the board.  There is no magic smoke, the DI now works, and life is good.

I think that most of the mics that are "working man's on stage mics" can probably take it.  Shure/Sennheiser/Audix/etc builds a huge part of their reputation on reliability.  If you could hit one wrong button and fry the mics, that would be a huge blow to their reputation for reliability.  They aren't going to let that happen.  Now, if you find some vintage mic that was made before phantom power was invented, I wouldn't try it.

Joe's right.  I didn't want to throw the big generalization out there but with the qualifier he added it should give a rule of thumb guidline.   Then there is the other myth that my phantom power will "blow up" the soundboard.  Ain't gonna happen, unless it is an even bigger POS than a Beringer or was made before 1960.   And the other statement that I used my TRS because I didn't want phantom on that cable....TRS can carry a phantom signal perfectly.

  And the other statement that I used my TRS because I didn't want phantom on that cable....TRS can carry a phantom signal perfectly.

I think it was me that said that in the DR680 thread. Of course a three conductor cable can carry phantom..it has three conductors....it's the R4 that I mentioned that sends phantom on the XLR but not the TRS portion of the same combo jack.

And I'm still going to make absolutely sure I never send phantom to the outputs of someone's console no matter what anyone says. Almost all modern devices have circuitry protection to avoid juice flowing the wrong direction. But what happens if you blow a fuse and the show comes grinding to a halt? That's not going to be me.

On topic....I've never run across a dynamic mic that could not tolerate phantom power.....however do not try it with a ribbon. You might get the smoke.

[kirk97132]

I'd find it extremely odd that the TRS didn't carry the phantom power also.  I did a real quick look at the manual it doesn't say one way or the other.  Have you ever tried to run phantom n the trs? just call me curios.   ON another note, look for a PM I still didn't get a reply  about the bag so it looks like it's yours

yeah think about it all the low end boards have channel 1-6/8ish PHANTOM ON. The levels change on this mic when you turn on phantom

Phantom power's actually designed so it doesn't affect dynamic mics, so should be 'invisible' to them (both signal wires have 48V going down them, so the difference seen by the mic is 0V).

Old style T-power (only really on broadcast kit now), on the other hand will toast dynamic mics as the voltage would be across the coil, causing it to heat up

So they saw the issue coming and that's why they get away with having all X channels have phantom on.
