How it works
IASUS Noise Terminator throat mics are different
from conventional headset communication systems.
Standard boom microphone systems are based on
traditional acoustic induction from sound waves
in the air. By contrast, NT 3 microphones pick
up voice signals via vibrations generated by the
user’s larynx through an aluminum transponder
that rests on just off the center of the throat.
This way, our throat mic systems “eliminate”
background noise by simply not picking them up,
making NT 3 ideal for use in noisy environments
and in situations where quiet, covert communication
is necessary.
A lot of throat mics use a double-transponder
design in which each transponder rests on either
side of the throat. This is not ideal, because
most people do not have perfectly symmetrical
necks, which leads to an imbalance of the transmission
wavelengths from each transponder and causes distortion.
IASUS has engineered the NT 3 with a single transponder
that hits the “sweet spot” about 1
to 2 inches from the center of your throat.

How to set it up:
Plug the mic cable into the audio input port of
your device of choice (2-way radio, mobile phone,
Xbox, computer). Insert the contour molded earpiece
so that it sits comfortably and securely in your
ear. To talk, push and hold down the PTT (Push-to-talk)
device, which can be clipped anywhere you find
most convenient. If the sound quality is muffled,
move the transponder further away. You should
keep readjusting the throat strap and testing
the unit until you find the sweet spot. It will
be different for everyone, depending on factors
such as your individual anatomy, voice quality,
and facial hair. Moving the transponder closer
to your voice box at the center of your throat
will boost the volume, but may cause distortion.
Everybody has a sweet spot that balances volume
and clarity; when you find it, fasten the strap
securely at the back.

Audio Hazard:
In particularly noisy environments such as inside
clubs, at concerts, and on top of motorcycles,
pairing the NT 3 system’s earpiece with
an earplug is a MUST. This is because in order
to register sound, the brain processes the dominant
sound level from either the left or right ear.
That means that when using the NT3 in a loud environment,
the volume of the audio source needs to be louder
than the external noise in order for your brain
to “hear,” resulting in potential
loss of hearing in high volume situations.
4.
Compatibilities:
The NT 3 system works with most popular mobile
phone and 2-way radio models.
Better audio sources—such as higher-end
radios—result in better communication. Certain
low-end radios are not up to the performance specifications
of our throat mics. We recommend pairing our headsets
with higher-powered UHF radios.
5.
When using the single earpiece in a noisy environment,
I still cannot hear clearly. How can I fix this?
In particularly noisy environments such as inside
clubs, at concerts, or while under heavy fire,
pairing the NT 3 system’s earpiece with
an earplug is a MUST. This is because in order
to register sound, the brain processes the dominant
sound level from either the left or right ear.
That means that when using the NT3 in a loud environment,
the volume of the audio source needs to be louder
than the external noise in order for your brain
to “hear,” resulting in potential
loss of hearing in high volume situations. Plugging
the open ear prevents this sensory imbalance.

Why doesn't my phone's voice activation function
(VOX) work with the Noise Terminator Throat Mic?
IASUS Noise Terminator Throat Mic systems work
quite well with the voice activation (VOX) functions
of many cellular phones. However, users must first
re-record the voice tag using their throat mic.
The phone's software will not match the user's
voice when using the Noise Terminator with a tag
recorded under normal conditions. Also, remember
to wait for the signal from the phone first before
speaking to activate the voice tag.
7.
The sound quality coming from my transponder isn’t
very good. What’s wrong?
Usually this is simply a matter of finding the
ideal location for the transponder on your throat.
Everybody has a “sweet spot” that
balances volume and clarity, and it is generally
found about 1 to 2 inches from the center of your
throat. However, its location is different for
everyone and depends on factors such as your individual
anatomy, voice quality, and amount of facial hair.
Moving the transponder closer to your voice box
(at the center of your throat) will boost the
volume, but may cause distortion. If the sound
quality is muffled, move the transponder further
away from the center of your throat. You should
keep readjusting the throat strap and testing
the unit until you find the sweet spot.
Another potential cause of poor sound quality
is the device you are using to transmit the signal.
Better audio sources—such as higher-end
radios—result in better communication. We
recommend pairing our headsets with higher-powered
UHF radios. Certain low-end recreational radios
are not up to the performance specifications of
our throat mics and can interfere with their performance.
8.
There is a very loud beep sound when I use the
NT with my FRS radio. How can I get rid of this?
Pressing the CE+ button when you turn on your
FRS will remove this loud sound.
9.
My radio will not charge.
Please make sure that the radio is positioned
correctly on the charger so that all four contacts
are lined up with the charging rails.
10.
My radio continually transmits when I plug in
my headset. What's wrong?
You need to make sure the radio is powered-off
when you plug in the headset. The headset should
function normally after the radio is powered on
again.
11.
My helmet speakers fit too tightly.
Certain brands of helmet and headgear are designed
for a tighter fit and may not accommodate our
speakers. Please determine whether your helmet
can comfortably accommodate the extra 1/2 inch
of helmet speaker on each side before your purchase.

How do I shorten the length of the acoustic coil
using the metal adaptor?
