Headset cabling
This impedance adapter connects a headset or flight helmet with low microphone impedance (approx. 5 ohms) to a high-impedance intercom used in civil aviation.The U-174/U plug of the headset or helmet connects to the adapter’s socket. The adapter connects to the intercom via two standard aviation plugs, PJ-055 and PJ-068.The adapter converts the microphone signal to suit the intercom. Headphone volume can be adjusted using the integrated control. No batteries are required.FeaturesLow-to-high microphone impedance conversionFor headsets and flight helmets with a microphone impedance of approx. 5 ohmsHeadset/helmet connection: U-174/U socketIntercom connection: PJ-055 and PJ-068 plugsIntegrated volume controlBattery-free operation
