Does the 1124 convert unbalanced inputs to balanced outputs?

Yes. As far as I know, any pro audio component with both balanced and unbalanced inputs and outputs will convert an unbalanced input to a balanced out.

But if level is too low I will need a cleanbox, Samson S-Convert or something like a MIC2200

Nothing is needed for the BFD's input. A converter is needed only if the signal from the receiver isn’t enough to drive an outboard pro audio amp to its maximum output.
