DESCRIPTION
The Tactical PTT/VOX Interface Module with Ear
Microphone consists of two parts, the Push-To-Talk
(PTT) / Voice Operated Transmission (VOX)
Interface Module and the Bone Conduction Ear
Microphone.
The PTT / VOX Interface Module is equipped with
high performance VOX interface and a large PTT
button. The guarded ring around the PTT button
secures the PTT button from any accidental actuate
and can be removed when situations require.
The superior VOX interface is enhanced by high
speed Digital Signal Processor (DSP) and detects
only signal matching to human voices. The VOX
circuit will be set off and recognized steady and
trouble-free VOX transmission even under intense
noise.
The module ensures transmission without clipping
the initial part of the speech by temporarily storing
the voice in memory and release it in tune with the
radio’s ready to transmit state. The built-in digital
audio amplifier helps to increase the radio’s volume
with a lower audio output. The module operates on
electrical power supplied from the radio.
The Bone Conduction Ear Microphone is equipped
with a high performance bone conduction
microphone and receiver built into the ear piece.
Unlike the conventional boom microphone, the bone
conduction microphone picks up your voice directly
from the ear canal, so ambient noise is minimized to
its lowest level.
