Volunteering at Sydney Mardi Gras

I volunteered last Saturday for Sydney Mardi Gras and my role was helping coordinate the media team on the parade route. After Fridays session on condenser and dynamic microphones I was curious as to what microphones the media were using for interviews. I politely asked one of the camera men while they were setting up and he was able to tell me they were dynamic wireless microphones. I did not want to distract him further however in hindsight I wish I asked for the model and make as well.
