Voice echo issue on zoom webinar

I'm having an echo issue with 2 way communication for zoom webinars. I have live participants in a building atrium and people dialing in. When someone in the atrium talks on a microphone, the people dialed in hear the person echo. But if a remote person talks, their voice sounds fine coming through the speakers in the atrium. 

 

Here is my setup. I've also attached a layout of the setup

1. Allen & Heath QU-16 sound board

          a. Handheld microphones are connected (XLR)

          b. MacMini is connected (XLR to 3.5mm)

2. Roland VR50HD AV Mixer

          a. XLR connected from QU-16 sound board to Audio In

          b. MacBook Pro running Webinar Live stream USB to USB Streaming USB3.0/2.0 to USB

                     I. Microphone is unmuted (so remote people can hear presenter in atrium)

                     II. VR50HD is selected for the camera

    My first recommendation is that you should only have one microphone active in the atrium at a time. Next, check the placement of your speaker to ensure there is little or no opportunity for  it’s sound to be picked up by any microphones. 

    Question: which machines are logged into Zoom?

    Hello Ray, Thank you for the information, this has helped. I had 1 or 2 laptops and the MacMini. I removed 1 MacBook Pro and still had the other issue. But what I did is remove 1 MacBook Pro and plugged a 3.5mm to XLR from the sound board into the MacBook Pro hosting the webinar. This seems to have resolved the echo.

     

    Thank you.
