MIC PLACEMENT ISSUES
For the tie-clip mic (Radio Shack #33-3013), I have found it best to place it right under your lower lip. This gives
you maximum sensitivity and loudness. Experimentation will give the best results. If you are getting too many
breath sounds, you can also use a mic windscreen to combat this. If you use the boom mic (#33-3012), the headset is
more comfortable and can be worn under your helmet. The boom mic also has a unidirectional mic, which will help
reduce feedback. The tie-clip mic has an omnidirectional mic, which gives better voice pickup but increases
potential feedback. Typical electret mics are omidirectional, so consult the above list for feedback mitigation.
MOUNTING THE UNIT
If you are using the voice amp with a standard set of trooper armor, you can put the board anywhere you see fit. Try
and keep the unit away from water, sweat, or condensation, as these are not good for any set of electronics!! You
can fit everything in your helmet, chest plate, etc.
I would also recommend that you encase the board in heat shrink wrap, a project box, or other enclosure –
particularly if you mount it in your helmet. Sweat, water, condensation can make the board behave oddly and short
out components.
Also note if you are mounting speakers in your helmet, this is a feedback nightmare. You may end up having too
little volume with this setup. Moving the speaker outside the helmet will give you a better chance at high volume
and lower feedback howling.
The below pic shows one such location that is concealable but still provides a good amount of volume.
PROTECTING THE UNIT
If you are mounting the unit inside your helmet,
you want to make sure you do not get it wet
. That includes
condensation, sweat, etc. These things can short out the board and render it inoperable. A good way to protect the
board is to use epoxy, hot glue, or even heat shrink wrap. If you boards gets wet or stops operating, turn it off and let
