We just updated the Apple Remote control documentation to reflect the addition of Adjustable Impedance (input) and Pre-Calibration. You can find it here:
http://www.tortugaaudio.com/documentation/#document-5We still need to add separate documentation sections explaining both of these new functions in more detail. That comes next.
Also, as a side note it's becoming clear that we've likely outgrown the Apple Remote and that it's time to revisit a new/custom Tortuga Audio remote.
Cheers,
Morten
