General Description
The Telex Stratus 50-D is a medium-weight, active noise-reduction headset with
boom-mounted microphone. It provides up to 20+dB patented digital tonal noise
reduction of engine and blade noise, up to 15+dB of analog broadband noise
reduction, and 29+dB of passive noise reduction. At 90Hz the accumulative total is
50+dB of noise reduction.
Design Features (See Figure 1)
Fit and Comfort
The Stratus 50-D incorporates unique features that allow the user to custom fit the
headset for comfortable operation. Among the features is a headband design that
distributes ear cushion pressure evenly over the entire ear with no pressure points. A
detented slide adjustment on the headband allows the earcup to be easily raised or
lowered for proper fit. Contributing to the comfort fit is a yoke design that allow the
earcup to pivot in two (2) planes assuring proper performance to the head.
To adjust earcup pressure, a patented Comfort Cam is rotated to one of three tension
settings. The last component in the fit and comfort is the 1” cushion made from heat
sensitive slow recovery foam which will conform to your head to provide a perfect
seal while spreading the weight over a large area eliminating pressure points.
Boom Microphone
The Stratus 50-D utilizes either an amplified electret noise-canceling microphone to
eliminate unwanted cabin noise from entering the communication system. To assure
proper operation the microphone must be positioned perpendicular to the mouth close
to the lips, slightly off center to the mouth. To facilitate pilot/copilot wearing, the
boom rotates up to allow the boom to be work on the left or right side. To minimize
windscreen loss, retaining hooks are designed into the microphone housing to
securely hold the windscreen in place.
Cordage and Plugs
The Stratus 50-D uses shielded cables to protect against RFI (Radio Frequency
Interference) and EMF (Electro Magnetic Frequency). Strain relief is added to the
cords and plugs to provide protection from wear and tear resulting from normal
usage. The headset includes separate receiver and microphone plugs. The receiver
plug is set up for stereo usage, but a switch on the cordage controls stereo/mono
operation.
