Yo Ratorius of Rat:
You are asking questions that I cannot answer. But, if you contact the Yamaha site and post a techie, they will give you an "exact" answer.
I made contact with Yam about a couple of things I wanted to know and got a very prompt response via E-mail.
Since you seem more in touch with more than I touch, I suggest you contact Yamaha for answers because not too many on this site are using the 2816/4416 at the moment; however, it will grow.
Happy New Year Rat
