Stereo Mono Switch
This switch is located on the Y-cord (Figure 4). Set the switch to stereo
for aircraft with a stereo intercom system. Set the switch to mono for
monaural intercom systems or for direct connection to the aircraft radio.
Cellphone/Audio Interface
The Echelon 25XT includes a unique amplified interface allowing for the
connection of a cellular telephone and an audio input simultaneously. This
configuration allows the user to set up before take-off and eliminates the
need to re-configure cords and equipment when operating the aircraft.
The other unique feature of this interface is the ability to obtain power
from the aircraft’s possessive communications system. This feature
results in increased battery life for the ANR system while maintaining the
benefits of an amplified interface. By amplifying the inputs, the Echelon
25XT allows the user to adjust volume level at the headset contributing to
the ability to not need re-configuring while in flight.
The Telex Echelon 25XT cell phone/audio interface has been designed to
function with the widest array of cellular telephones and portable audio
devices. There are cell phones and audio devices on the market not
designed to industry physical and electrical standards. These devices are
not guaranteed to function properly with the Echelon 25XT headset.
