No worries here...it has both, RCA's and XLR's, but ONLY USE 1 AT A TIME !!!!!!!!!!!!
And yes, the XLR's are jumped from the RCA's, but fully functional...depending on the preamp, the worst case scenario is about a 3 dB drop...bottom line, the XLR's are fine...however, me personally, I really, really, really don't like balanced. I love the richness and tone colors of under-over tones of single ended...all about goosebumps....
