A key point about those inputs: only 4 are phantom-powered. The other 2 XLR/TRS combo inputs are not.
specs say
Phantom power +24 V/+48 V (independent ON/OFF for INPUTS 1–4, A and B)
nothing in the quick guide indicates otherwise
BH vid also says 6 phantom
it seems like in line in mode, 1-4 are standard balanced line in, and A and B are basically DIs. But all can be used with condensor mics with phantom
other thoughts:
i HATE devices that have hold switch combined with power. ive accidentally turned off my A10 by unlocking it too far during recording. hopefully it has a well-timed long press on the off switch. A10 is a mere 1 second
not lining up to buy this monstrosity, but for those who can handle the form factor, 6 ch phantom+ the removable XY mics for $400 is quite the bargain. At their current $50/channel price ill hold out for my $100 F2
depending on the cost of the ambisonic unit, it would be cool just for that. ambisonic+ 6 more channels to play with to compare
are zoom capsules any good? they tout 136 dB max SPL for the stock XY
