Well, assuming you’re staying out of the top meter LEDs on the 96 on your least-compressed and most dynamic tracks that need all the oomph they can get, and probably better not intentionally going into the LED below it and leaving that for accidents (actually not a whole lot of LEDs over 0dBVu to work with on it, it looks like), I’d be curious if you ever run out of channel gain. It’s possible the Xone 96 knobs do increasingly more boost towards the end of their rightward rotation… a more linear curve, if you will.
When you have only one channel up, you’re running with that fader all the way up and no crossfader dip affecting it, correct?
If you do ever run out of channel gain/trim knob boost doing the above advice, you might need to find a new maximum peak on the Xone 96 metering to work within than what you’ve previously used… like only going up to +3dBVu on your most dynamic tracks, or even just up to zero.
I would also not be surprised if there was some way to increase the available gain in the 96 innards somewhere, like some jumpers or something… A&H has a history of that sort of thing.
