Right, I found one. It also has three styles of connector (XLR/TRS/RCA) so
cabling will be easier. They are available from a local store too which is
another plus.

I will order the boxes (I think 6 lines worth will cover anything possible
with the mixer we have). I was going to put in a network cable anyway (if
we use it right now or not) but could aslo put in optic line(s). Are they
subject to degradation with time if not in use? It is not a long run at
less than 100ft (this includes running it up above the ceiling and dodging
open rooms etc. The dx from stage to mix is less than 50ft.)
