split snake and phantom power.

<< < (2/2)

Chris Hindle:
General protocol says console closest to the stage should supply phantom.
With a Transformer split. phantom doesn't pass thru the xfmr, so it must be supplied to the direct split.
Usually the shortest whip. Generally you lift all the grounds but one.
with a non transformer spit, I consider it bad manners to have phantom on both boards at the same time.
If both boards are 48 volts, i wouldn't expect any problems, blocking caps and all that, but phantom can be as low as 12 volts on less than big boy boards.  How will a 12 volt board deal with 48 volt blocking?
I dunno.

We are playing a new venue that doesn't have one so I purchased an EWI split snake that is just a basic split, no transformers. The house board is an M32. From my understanding only one board should have the phantom on. I assuming it would make more sense for it to be our SQ5.

Since your band is using IEMs, are you also using all of your own microphones?  If so, then yes, the most logical way to proceed is to supply the phantom power from your SQ5, otherwise you will not be able to rehearse!  That assumes that you will incorporate the split snake into your IEM rig.  This is how it works for nearly all of the bands that come through our venue with a fully self-contained IEM rig.

I don't want to damage anything and just wondering if this is still an issue with modern consoles. Also if anyone has any other advice on using a splitter I am all ears. Thanks

As others have said, without a transformer split either or both consoles can supply phantom and with most modern gear it wont really hurt anything if both do although that is generally frowned upon. Most people supply phantom from the console with the shortest cable length to the mics, usually the monitor console. If you are using your own mics, Id supply phantom from your SQ5 so the house doesn't have to worry about it.
I did want to give a shout out for the EWI snake! I love their gear and the folks at AudioPile!
