Can I use GoXLR Mini in conjunction with GoXLR?

In short, no. Because GoXLR processes all of the audio on the physical device, it would require virtual routing to work which creates stability and latency issues.

However, if you are on a 2 PC setup, you can plug GoXLR Mini into 1 and GoXLR into the other, and plug the Line Outs and Line Ins between the two.

You'll be able to control Stream PC programs on the Mini and Game PC programs on the GoXLR. We'll probably have some sort of guide for those who wish to do this in the future.
