The art of public speaking will lead you to find it is pretty common to
have multiple wireless microphones going during the same public
speaking engagement. The AV crew running around that sets everything up
usually makes sure that they are all on different frequencies so that
no cross over occurs. You should still double check the MIC anyway. BUT
WHAT ABOUT MICE? OK, OK, AV people running around are not rodents, but
if your Mic does not work, you might say "Rats!" Same way with your
When speaking in Thailand last week I ran into a situation that has
never happened to me or the other seasoned presenter before. We each
had a Logitech Trackman RF Mouse. RF stands for "Radio Frequency" which
means that the wireless mouse doesn't have to be in line of sight with
the receiver like an infra red mouse would. It also means that I
couldn't keep my mouse from moving the cursor on his computer (the
other guy was on right after me with no break).
We tried every trick we could think of with no luck We finally decided
to shut my whole system down quickly after I was finished and boot his
up as fast as we could while he made some opening comments to the
crowd. The art of public speaking involves working with other
speakers, and working with audio-visual technicians.
With more and more wireless technology being used during presentations
you must thoroughly check out all systems and consider presenters who
are on both before and after you. This is yet another part of the art
of public speaking which is a reason to be there early and find out
what is going on during other programs.
Had we not noticed this ahead of time he would have had a really shaky
beginning to his program . .. if the program were switched . . . it
could have been me! Like a Boy Scout, "Be Prepared" with frequencies
and other speakers is part of the art of public speaking.
