What do you do when you are requested to speak on a topic on which you are seriously passionate, but it is one that is obscure or one that has received little attention from your audience?
You may fear you will run the risk of talking over people's heads, and what good is that? Then, you look to the other extreme and decide you could simplify the topic; however, you do not want to talk down to your audience, creating overly elementary points, and subsequently creating for yourself (and possibly your audience) a boring experience.

Others have something of a fear of a mic, cringing at the sound of their voice being broadcast through speakers and wanting to stay as far away from a mic as possible. When you take to the stage, you should assume you have an important message because ... well ... you do. You've spent time researching it, crafting it, refining it, and you should want everyone to clearly hear you and your message because it's an important one.
For a speaking engagement, so that everyone hears your voice at the same volume no matter where he/she is seated in the room, a mic should be used if one is made available. I recommend you always ask well in advance of your event that one be provided for your use.
You should use a mic not only for the benefit of the audience but also for the purpose of ...
