Phantom Power

Postby karpelproductions » Fri Nov 02, 2007 1:04 am

I have a sony wireless microphone transmitter meant for ENG use with an 1/8" output. I converted this 1/8" output to XLR and it is going to a sound board in my studio. can i run phantom power out of my board even though the transmitter is unbalanced?

Welcome to the forums!

The answer is short (after a bit of quick research): No! Do NOT connect unbalanced devices to a phantom power source.

More info here: Mackie PDF "Balanced Lines, Phantom Powering, Grounding, and Other Arcane Mysteries (top of page 4)
and Musician's Friend - Tech Tip - The Gigging iPod/Laptop Musician and the Phantom Menace:

The long answer: Yes, but you'll need to find a way to remove phantom power or run through a good balun DI.
