Production Switchers

We just installed an Ultrix Carbonite along with a Touchdrive TD2. I've really been appreciative of the Procamps/Color Correction for our sources. However, we just put in two new cameras and wanted to get them matching. So, I made sure the procamp and color correction for the cameras was off, white balanced both cameras, and displayed them on program through Aux 2. Switching between cameras showed they matched perfectly, but showed up with much less red in the image than our camera monitor. 

So, I kept one projector on Aux 2, and soft patched the camera directly to the other projector. The projector receiving our camera directly showed more red in the image. It feels like there is some sort of color correction or processing being applied to either our Aux bus or MEP/P (like it can in the Acuity), but I do not see any options for that in our Dashboard. 

So, is there a way I can get our Aux Bus to color match our sources? As a video venue, our main campus was wondering why we needed to color correct their shots so much. And I think this is a huge reason.

Make sure you have the correct color space identified in the Reference menu.

The only way to verify that there is some kind of signal path from the switcher causing this would be to send Colour bars through an input .. and then look at that source through the switcher path and then direct an output of the Ultrix.  Put that into a Vector scope and switch on the output between source direct and the Switcher PGM/Aux Output that has that same source direct on it.

Thanks for the reply. Our color space in the reference matches the color space of our inputs: SDR and BT.709. 

If I'm able to get a vector scope from our main campus to do this test, what would we do next if it still shows to have a color mismatch?

It doesn't show up as much in a video or photo as it does to the eye, but the left projector in this image is a straight camera, and the right projector is the same camera on the top image and the camera through an Aux on the bottom image. You can easily see that the camera through the Aux shows up with much less red in it.
