Hello Everyone. I’m trying to locate some help regarding what seems to be a phasing / extreme hollowness when both Mic inputs are live.

I work for a News Network, and use the current version of Vmix for our production. Recently we renovated our studios a few weeks ago and since then have ran into an issue with audio where if we are conducting an in studio interview, one of our Mics will have this really bad hollowness, both mics and channels are totally fine and clean on their own, but when both are live it seems to be the last Re-loaded input is good but the other is bad.

Now I say Phasing, but both mics really aren’t close enough to each other to cause this, both are pointing at their own sound sources and shouldn’t be phasing at all, our other studio (Studio 2) has the news anchor and guest at the same distance from each other as Studio 1 (the issue location).

We use Sennheiser Wireless Lapel Microphones XSW2-ME2-B and plug directly into our production PC’s (recently eliminated the soundboard in the production chain for ease and studio automation).

Any help at all would really be appreciated.
Thank you!

Yes sadly it’s coming through to the recorded video and not just my headphones.

I believe we usually do have the windows audio muted.

We have changed RF’s on the transmitter too just incase it was frequencies causing this.
But even that hasn’t made an effect.

Through USB, mics are plugged into PC and would be captured from the sound card.

Again individually no issues at all.

During an interview turning off the opposite mic instantly makes the bad one go back to normal and clean.
