SM7B/CloudlifterZ/MVi Ground Issue??

Just hooked this rig up.

SM7B/CloudlifterZ/MVi/Laptop

Terrible ground buzz. If I put my finger anywhere on the MVi the buzz gets quieter but still crackles a bit.

XLRs are brand new. Entire rig is brand new right out of the box. I've tried each XLR 7B/MVi and no buzz.

Help.
Thanks

(I also snagged some ATH-M50x per recommendation and they seem to be too quiet did I get the wrong headphones?)

The headphones are fine

It sounds like the mvi is either a piece of crap or broken

The buzz only happens when the cloudlifter is plugged in so I'm thinking that's the issue. I'm waiting on a call back from them.

You do have the phantom power switched in?
The cloudfilter needs 48V phantom power
Is the MVi connected with USB (Phantom Power: USB: +48 VDC, iOS: +12 VDC)?

If I unplug things from the mic going back the buzz stays until I unplug the couldlifter.

In other words... If I unplug the mix I still have ground buzz. Once I unplug the Cloudlifter it goes away. Bad Cloudlifter? Or is cable still possible?

- Any difference if you run the laptop on battery alone or using the laptop power supply plugged in?
- The Cloudlifter shouldn't cause a problem, but could put noise out if the phantom power isn't well filtered that powers it.
- I don't see a real 'gain' control on the MVi thingy that I looked up. The mic 'gain' appears to be controlled within software. If you change the gain in the software does the headphone level change?

Or phantom power to low.
