Isn't 8+4+2 == 14 channels at 96K?

Vs. 8+8+2 == 18 channels at 96K?

You then *maybe* get 2 more outputs using the headphone output if it is 
addressed seprately, but there's no corresponding input, so at 96K it 
looks like 16 out, 14 in with the right converters hooked to ADAT.

My DigiDesign 002 Rack is pretty much a duplicate of the Multiface 
except it doesn't support the ADAT interface at 96K at all, to I only 
get 10 in, 10 out. My headphoens are always a copy of the Master Output.
