The Sonosax mini R82 is very small and portable.

This is about as small as you can get - I had one for a week (long story) - It's about the same size as a Sony PCM-M1 - has 4 analog inputs and 8 digital, can record 10 tracks and has timecode
2 tracks are unbalanced on mini-jack no pre amp, the other 2 channels can be fed balanced or unbalanced, and can provide 48V phantom, 48V/5V parallel, etc and are on 2 7 pin binders (although you can wire everything through one of the binders).
I was going to make pig tail with some circuitry that would allow a direct connect to a KCY (you get 48V high out of the gate, just needed to figure out how to go from 5V to 6.1V or 48V down to 6.1V for the fet voltage) but I had to give the unit back before it could be realized.
It's a pretty sick little recorder - but at $5K what would you expect.
