INTRODUCTION
The Lynx Micro System has been specifically developed for use in
the high-noise environment of open-cockpit aviation where noise
attenuation and microphone noise cancellation are primary concerns.
The Lynx Micro System Radio Interface Unit is purposely designed
for use with Lynx Micro System Headsets and airband radio
transceivers, to provide pilots with all the facilities necessary for high
quality radio telephony.
The Interface Unit
The interface is manufactured utilising the latest techniques in
microcircuit design, and surface-mount component technology, to
produce an exceptionally compact unit (fig 1).
Developed specifically for use in close proximity to engine ignition
systems, the interface electronics are designed to be virtually immune
to electrical interference. All electronic component parts of the unit,
including the leads and connectors, are screened to prevent noise
from electromagnetic radiation. In addition to passive shielding, the
processor includes dedicated electronics to actively filter and remove
interference from the audio signals passing through the unit.
The unit uses very little electrical current, especially during stand-
by, and has no noticeable effect on headset battery life when used
with a Micro System Headset.
Radio Configuration
The Radio Interface is intended for direct connection to a hand-
portable radio and can be supplied to work with all common types of
radio transceiver.
