Would running a DI box help signal hum for a MBFM or MBSID?

My MBFM is a little noisy and am wondering if a DI box would help get rid of some of the buzz. I read a post somewhere here where someone fixed a hum problem on their FM with different resistors and capacitors. I'd rather not open up my midibox and am looking into a mixer that uses stereo xlr inputs for the line level channels (not normal I know)

So I am wondering instead of buying more 1/4" to xlr cables or adapters, would a DI make more sense in the long run? Or should I just desolder the xlr jacks on the mixer and put TRS jacks in instead?

What is the impendence of the MBFM? I built it using the standard equipment list off Smash's site.

Right now I have my MBFM going directly into a cheap behringer 1/4" line in but want to take a crack at using good eq while recording.

What kind of noise do you get? 50/60Hz hum or digital noise or?

In short: No, a DI box won't remove the noise that is already in the signal. Fix that.
