Balanced and Unbalanced outputs

Hello all,

I have a Krell HTS 7.1 pre/pro. Right now all my preouts are connected using balanced outputs (XLRs). I just bought a Definitive Tech 3000 center speaker that has single ended input (for its built-in powered sub). It recommends that I connect the center out on my pre/pro to the input of the Defitive Tech 3000 for best result. My question is can I use both the XLR (connect to the amp) and singled ended outputs (connect to the DT 3000) at the same time? Will this damage anything to my Krell 7.1? Or am I better off by using single ended output with a Y-splitter to connect to the power amp and the Definitive C/L/R 3000 at the same time? Again, this is only for the center channel.
Thanks a million,
Should not hurt a thing on either side. Keep your XLR cables and connect your center channel with the rca cables and enjoy.
