Patchbay, one end, Bantam TT, to XLR male, to 1/4" female adapter, 1/4" male adapters on RCA to 1/8" mini plug > M10. Perhaps too many adapters but the only cable I found was TT to XLR. I'll admit I know nothing about what comes out of the patchbay but it was suggested by my friend that the patchbay will/may be used to get what signals we need, and it is very convenient to the area where we currently set our decks for patching out.
ok sounds lie you are reinventing the wheel...way too much work (I think) for this. Sooooooo......lets go back to square one. What do you want to record from the SBD?
1.)two channels?
2.) "SBD" feed?
a.)SBD option A: what is being sent to the the house(most common type of SBD feed)
b.)SBD option B: O custom mix done by SBD operator mixed just for you( Least common type of feed and requires extra work for sbd guy)
3.) mics run through sbd preamps and sent to your recording deck?(not common but can be done, requires a little work for sbd guy)
4.) Multitrack feed? IE: something like an alesis HD-24 that allows 24 seperate mono tracks of recording( maybe a Tascam DR-680 with 8 tracks)
Bottom line what are you looking to get from the set up you are discussing. In 20 years of recording I have never needed a patchbay until I wanted to do multitrack recording and even then it was not necessary just a convience item for me. Let us knowwhat you are trying to accomplish and then we can make some recomendation for you to check out..
