Nawwww............just a little slow on the keys tonight. Cough syrup laced
with phernegan and codiene tends to make me a bit sluggish and out of
phase....but it's definitely taking the edge off this flu, which has evolved
into walking pneumonia and a serious sinus infection.
In a nutshell.........don't daisy chain MECs from a house clock. Use
individual clock outs to the individual clock ins of the MEC
I terminate my MEC inputs........don't know if it's totally necessary, but I
do it and it seems to have added stability.
Leave your house clock set to 44.1 (if that is what you're using)
and set you default .ppj to 48k. Don't argue or wonder why. Just do it. The
system should sync reliably if you do this and it will definitely be
unreliable if you don't.
The 442 may add *instability* to a situation like this because it will
initialize at boot up of the computer whereas the MECs initialize when you
start Paris. I only had luck with a 442 on my multicard system if the 442
was attached to card A. Still, it could have been for other reasons, so it
wouldn't hurt to give it a try if you need it. There is no reason though
that you should have to have it if it's not necessary.

Sorry......this should have been the MEC *outputs*

Well, shitster, Deej. Hope you get to feeling better. If you have any
codeine left over....oh, never mind....
It's a no-go. Set default project to 48, same basic problems.
I'll have to order the BNC terminator caps. Athens is too po-dunky to carry
such things.
Couple questions:
1. What's the maximum length for SPDIF cables in my scenario?
2. Would adding a 4th MEC set things up in a more stable sceanario?
I guess worst-case scenario is running the two Kurzweil boxes via analog. I
wish to god they had just put BNC connectors on them. I don't understand why
the whole system will work perfectly one time out of ten....

Also, my cable supply house sells 1% and 5% terminator caps, whatever that
means.
Which one, or does it matter?

A terminator is a resistor.. the 1% / 5% deal is the tolerance to the value.
So basically, a 68 Ohm resistance could be 1% or 5% off either direction
from that value. Go for the 1% IMO.
