Ken,

Could be. I forget. Someone will confirm, if so.
I just wanted to point out that in terms of fidelity, there is no difference between XLR (balanced) and RCA (unbalanced) connections.

Oddly, my large "Handbbook for Sound Engineers" doesn't address the question, likely because RCA connectors are never used in pro audio and sound-reinforcement applications.
