Jack sockets provide an alternative method for connecting audio accessories to the AIU Mk1.

The jack sockets are an alternative format for the AAI2 connector.

One Jack socket designated ‗MIC‘ supports:

 Microphone audio.

 Accessory ID.

The other Jack socket designated ‗PTT‘ supports:

 PTT.

 Accessory key 5 only.

It should be noted that in the AIU Mk1 the Jack sockets share the AAI2 audio

AAI2 connector at the same time.
