You are correct on both counts, although there are provisions to add 
preamp modules to the inputs. And they are not cheap. And what Jim Lux 
is saying is that there is some time offset between the two DSP 
receivers. We can pretty take what Jim says to the bank -- his day gig 
is (was?) as part of the teams that put us on Mars and other cool 
places. Jim and I are both contributors to the ARRL Handbook.
