Great video! I am curious, however, how the total "quality" of the 18-stories of singers was realized? For example, were there microphones, amplifiers, sound mixers, etc. on each floor?
[Editor's Comment: You are indeed a meticulous observer. We need talented people in our churches to help us see what many are unable to see. Your questions are good ones. I wish I knew the answer. Sound, electronic, and sound mixers are above my pay scale. I would like to encourage you to do some research and find out the answer to your questions. Then, report back to us your findings and let us learn what you will know.
Thanks for writing. You made my day.]
