We are currently using the USB MXL microphone with Large Meetings for Rooms. The quality is good but you hear all noises in the room instead of just the presenter. I 'm searching for a compatible wireless microphone/s that could be easily moved depending on where the presenter is.
There are quite a few microphones that you could use, just depends upon your current setup.
This article may help guide you on choosing something that'll work best with RC Rooms. Otherwise, you could reach out to your Account Manager who may be able to help get some more answers for you :)
