Hi Folks,
I ordered the EventBright power supply from Amazon.
On the web it shows a three-prong, grounded plug.
(And if you scroll across, a two-prong as well.)
It came with a two prong, un-grounded plug, and the body of the unit is two-wire, so no ground.
The Mackie power supply is grounded.
For mic cables I prefer the shortest ground path.
I'm returning this adapter, and getting one that is grounded.
This looks like a good choice:

Or this one, with a common IEC AC connector:

Thanks and good health, Weogo
Ever plug a grounded AC cable into a miswired outlet? You'll be glad you had a 2 wired plug. It's isolated from all the noise you will find on building ground lines. As long as it's approved by UL or other agencies you're fine. I would keep it. Lots of high end HiFi gears went that way for lower noise.
