OBS Studio: Color Range / Color Space

When streaming our shows, we connect our Edirol V8 mixer to a capture card and we use OBS to stream. OBS has “Color Range: Default / Partial / Full” options both for the capture card (see pic) and for the output (pic).

How would you set these settings?

Also, would you set Color Space to 601 or 709 and why?

(empirical tests didn’t show any differences; answers on OBS-specific forums vary and usually people there have very different setups and needs than us)
