Playing with the idea of setting up a surround sound system using UFX III. However, got a question that must be sorted out first.

Say, I have a Baby Face FS feeding 5.1/2 channels into the UFXIII

The UFXIII is controlled by PC1, Babyface FS controlled by PC2.

When both are on, UFX should be able to take the signal from PC2 and send them to Line outs without any issue.
but what happen if PC1 is off? The UFX is separately powered, so it should stay on, However, can it still receive signal from the BabyFace and process it to Lineout without switching to a different operational mode?

I know it will work as a standalone mixer if I set it to it. just wondering if it can continue to process signals without changing any settings after PC1 is off.

thanks
