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.
