How hard is it to use the lx 20 or the black face adats with an xt20. What kinds of problems will I have to deal with as far as editing and linking the machines?
The only problem isn't much of a problem. You'll have to record at 16 bits on the 20 bit deck. You can play black face adat tapes in a 20 bit machine but obviously you can't play 20 bit tapes in a 16 bit adat. As said above, the two machines will chase and lock just fine.
