Oh, I see. The manual diagram for the current model has them in different places.

I moved my right speaker connectors temporarily over to the EP500 high level inputs, and I am hearing some bass, now. So that's a relief. Most likely, the line-level input is just broken -- it feels a little loose. So I guess I'll order a male XLR to male RCA cable (I hope that's right).

Thanks for the help.
