Predistortion Outputs?

I'm curious what the two Predistortion Outputs on the back of the PG-XL are for?  Perhaps something to do with a future Adaptive Predistortion feature?  Is there a link to the PG-XL manual available yet?

They are an attenuated tap for RF feedback needed for adaptative pre-distortion.
The PGXL manual is still in draft form.  It should be made publicly available in the near future.

Tim, is the purpose of the adaptative pre-distortion feature to provide less distorted  transmit audio?

It isn't just for audio as it operates on the transmitted RF.
