i suspect the problem is not an issue with the mic system itself, rather
the
use.
if mic sensitivity is adjusted to minimum and you still get overload
further
reduction can be obtained by adding layers if windscreen foam and/or
moving
the mic further from the sound source.
sometimes the mic element itself goes bad or gets noisy. a new lav
element
restores the system to perfect operation.
if this is the case a Countryman brand mic element is one of the best.
thay
are not cheap but will cost less then replacing your system.
in the case of a whisperer... just let him whisper and don't push up the
gain. he is doing it for dramatic effect. he wants people to listen in
breathless anticipation. pu****ng the gain merely enhances background
noise
and increases the probability of feedback.
IMO adding an AGC or gated AGC will be very problematic in terms of
feedback
control with a lav system.
even using a compressor will require careful setting and equalization.
with presentations like this usually a handheld mic is used and the
speaker
starts out with the mic somewhere around his or her navel so the poor
sound
guy has to struggle to pick anything up. then as the presentation builds
the
speaker moves the mic closer in until finally they are practically
screaming
into it.
in cases like this having a comp/limiter in the mic path or on the system
as
a whole would be a wise idea to prevent the pa system from clipping and
possible speaker damage.
the EW 122 has a dynamic range of about 110 dB see specs at
http://www.sennheiser.com/
the -30 dB setting might be used if the mic is clipped to a loud
instrument
(i.e. trumpet)
the 120 dB max sound pressure level is respectible.
