I get to say "so what" because you are ignoring the
situation.
Nope.
Effective teachers/lectureres go INTO the
audience. The use of a FBD allows much higher SPL levels.
Obviously, you have very limited experience with feedback. The usual rule of
thumb is that feedback destroyers are only effective if you let them hunt
for feedback modes, and then lock them down because if left in automatic
mode, they start hunting down and destroying parts of the signals you want
to amplify. Trouble is, feedback frequencies change pretty dramatically when
the mic moves around.
Botttom line, your roving lecturers will tend to destroy the usability of a
feedback destroyer.
Teachers shouldn't be limited by technology,
but empowered by it.
Agreed, but irrelevant to any discussion of the limits
enforced by the laws of phyiscs.
There are tools available to "push" the limits, like
compressors and FBD's.
Comressors tend to exasperate any signficant amount of feedback that you
have. I already pointed out one of the inherent limitations of feedback
destroyers.
Limiting contact with the audience
is not empowering or effective.
In my book, not loud enough, or feedback are pretty
severe limits on contact with the audience.
So? The proper and appropriate use of good eqing and a
FBD pushes back those limits so that the volume can be
sufficient in most cases and still allow the teacher to
enter the audience to interact with them.
I don't need to argue with you, I just need to let you have your way and
live with the predictable results.
Do you need some elementary education in the use of
compressors and FBD's?
Not hardly. It appears that your elementary education in their use will be
forthcoming. ;-)
