Going Live - what might i need to add to my setup live perf.

Eddie, everything you said is correct. However most direct boxes actually serve 3 purposes. First, they convert unbalanced to balanced. Second, they offer transformer isolation and a ground lift. Third, they act as a split.

As far as I can tell, the poster doesnt need the split or the unbalanced to balanced conversion.
There will be times, though, when he will still need the transformer islolation to keep a clean signal.

I recommend keeping these items in your toolbox for live performing.
For each stereo output:
2 trs to xlrm
2 trs to xlrf
2 standard mic cables /xlrm to xlrf (in pairs of different lengths if you want)
2 rapco isoblox

This way you are prepaired for short or long runs to trs or xlr with the option of isolation

I agree with the potential need for transformer isolation.
Modecai, this is the bottom line:
If your output is balanced, you do not need/ want a direct box. A transformer isolation, on the other hand, can be handy. A transformer isolation will keep any dc bias that might exist on the house gear from mucking up your sound.

wait...what is a transformer isolation

can I just use a 1/4" to xlr cable to go into the house board?
