I think Soren is probably correct. In A&H world, a stereo linked pair only uses a single fader on the board (which is really nice IMHO). The second channel in the stereo link will “disappear” from the fader layouts when stereo linked and will not reappear unless the channels are unlinked.
There are times where you will find that the preamps for the two stereo links channels are not set the same (or perhaps you need to set them differently for some reason). The good news is that you can still access the preamp controls for the linked pair individually if you go to the routing page and click on the input number at the top. Sometimes you stereo link a pair of inputs, but phantom power wasn’t turned on one channel when it should be, or the phase was flipped on one of the channels, or the gain setting was different, etc. Of course you can also unlink the stereo pair and the preamp controls for both inputs will appear as normal, but it is easier to use this method if you plan to keep the channels in a stereo link but need to change the preamp settings independently for some reason.
