Hybrid Mic Setup

Do you do professional audio or audio related things as part of your career?

If not, discuss AEC,  and mix minus with someone who knows about this sort of topic.

Open mics, mixing levels, PA systems and hybrid will be a challenge for audio feedback.

Does the room have a DSP?

Good luck.

Connect to Projector and room audio.
Turn off screen mirroring.
The presenter should ideally be the one hosting the Zoom Meeting and sharing the presentation materials. ...
Arrange displays so that Presenter/Zoom view is on the computer screen and the view of the participants is on the Projector screen
