I ran c1000s with a D7 straight into the line imput. Between the mics and the recorder you need to add line tranformers that boost the signal. Hosa makes a couple:
MIT-176 Mic Transformer, XLR Female LO-Z to 1/4" Male HI-Z, "Pigtail"
MIT-435 Mic Transformer, XLR Female LO-Z to 1/4" Male HI-Z
I used some audio technicas Cp8201 Same basic thing though. You'll need a 1/4" female x2 -> Stereo 1/8" cable which isn't the easiest to find, but easy to make. Hope this helps
