This conversion kit has been designed to allow the use of a David Clark H10-76 or H10-76XL low impedance headset in a general aviation aircraft. The David Clark H10-76 conversion kit includes a noise canceling electret microphone (high impedance) to replace the dynamic mic (low impedance) on the H10-76. it also includes an adapter to convert the H10-76's single U-174/U plug to a dual plug system (PJ-068 and PJ-055).
: Unscrew the existing mic on the headset and replace it with the PA-5X mic. This requires a small phillips head screw driver. Then you must connect the PA-75 adapter to the single plug of the headset and they are ready to go. No soldering, no cutting.
