xlr and rca on same IC cable??

I'm awaiting a new amp for my HT. (EAD pm 1000). My current setup is using XLRs. The ead only has rca. Changing cables on my Sunfire processor is a MAJOR pain due to it's location. Can I just change the connector on the amp side? If so, Any idea which Neutric # corresponds to the inner and outer parts of the rca?

Thanks
