Looks to be a Fender. I recognize the 5 yr warranty card hanging on the front of it. Can't tell which model though.
EDIT: Looks like it's possibly a G-DEC model.
There are some real beasts in that photo. Great pic
For this setup, the Xitones were guitar signal monitors so every player could hear every other player's Axe-Fx or G-DEC. In an earlier session, we used them with a Matrix amp for backline. In a different photo, you'll see someone (not me) set them up upside down.
Each player had his own guitar signal playing through a system directly behind him. In Dweezil's case the backline was stereo.
Some of the Axe-Fx IIs were in QSC KW112s, and some were in the Matrix GT800 and NL12 cabs.
There are three MFCs set up. James Santiago also had his pedalboard plugged in to the front of the Axe-Fx.
Some of the Axe-Fx units were split to allow two players mono into two playback systems.
We created MANY different multi-player setups on the fly like this.

Was the G-DEC just used to supply backing tracks?
No, the G-DEC is the "house amp" of this event. There are pairs of them (or more) in every building so students and teachers can practice/jam. As I mentioned above, the players here are going through Axe-Fx IIs into 4 QSC KW112s (Dweezil, James, Chris), or Matrix (Derryl and Tom). When Dweezil decided he wanted 7 people on stage at once for the summit, it became first-come-first-serve for Axe-Fx channels with G-DEC filling in the blanks.
