Mic pack for an audience of 8.
If even one of them is Deaf/deaf/hard of hearing and uses a T loop then yes
If you want the video to be usable then yes
If you want to produce an easy transcript then yes
If you are pushing the video/audio to another room for the other attendees, then yes.
I don't see any reinforcement speakers, so I think we can assume that the mic is there for good pickup for other systems - rather than to assist with his vocal projection
