The headset converter (Bose Lemo) is for use with aviation headsets or helmets fitted with Lemo panel mount plugs and allows the headset or helmet to connect to a lynx radio interface. The converter specifically designed for use with Bose, Lightspeed or Lynx Active Noise Reduction (ANR) headsets and helmets The converter can be configured to work with speaker impedances from 8 to 600 Ohms and dynamic, electret or carbon (Amplified) microphones. Active Noise Reduction (ANR) headsets can be powered from the converter, using the tip of the microphone jack plug, avoiding the need for a battery pack in the headset lead. The converter is backwards compatible with all Lynx intercoms products and maintains all the interface functions including selective PTT operation and microphone muting. The converter is very useful in syndicated aircraft where some users wish to retain the use of their Bose or lightspeed headsets.
