GENERAL DESCRIPTION
The Telex Echelon 100 is a medium-weight noise-reduction headset with amplified,
noise-canceling, electret microphone.
DESIGN FEATURES
(See Figure 1
)
Comfortable foam-filled headband pad and ear cushions. The headband pad
evenly distributes the headset weight, with no pressure points, for maximum
wearer comfort. The ear cushions combine comfort and light weight with excellent
acoustic seal. An outer urethane layer ensures long life. Gel-filled ear cushions
are also available for this headset for users who prefer this type. All cushions are
field-replaceable.
Boom Microphone:
The boom arm features a sealed ball-and-socket joint and
flexible boom for precise microphone placement on any head size. The boom
rotates overhead for microphone placement on either side of the head. The
microphone cartridge features a noise-canceling electret element. The cartridge
snaps on and off for easy replacement. The microphone amplifier is in the
microphone cartridge. It operates on current supplied by the aircraft radio via the
microphone jack. The amplifier output level is adjustable through an opening in
the earcup.
Cordage:
The microphone cordage is protected inside the boom arm. Shielded
wire throughout the headset protects against RFI and EMI. Strain-reliefs on all
cords provide maximum durability.
