How do I wire unbalanced outputs to balanced inputs?

Thanks @Sokel - that makes sense. I have already got the Wiim Ultra and want to use it. Like you said, the fact that it will not drive the amp module to its full capacity might be a good thing. Plus, I have a lot of headroom so it should not be a problem. Does such a difference translate to -6dB?

That's from the datasheet:

View attachment 408383

So,about 3.5V rms

Oh ok, so I suppose it's not bad at all. I can fabricate my own RCA male to XLR male cables.
