The X32 seems to be viewed as separate from everything else Behringer make and immune from "no berry" riders
I had already had an email conversation with Matt (said engineer) and we discussed options, both he and I had X32 and Qu16 at the top of our respective shortlists and he had considered the DL but discounted it because of the lack of multitrack recording.
The tech rider in question had been drafted after a particularly bad gig where the promotors idea of a suitable rig for an award winning UK folk trio in a 350 capacity venue was a Peavy mixer amp and two HiSys 2s (and only two mics...)
The rider actually said "Any mixer with BEHRINGER/MACKIE or any other similar unprofessional equipment is not acceptable. Midas/Yamaha/Soundcraft are most likely able to cover our requirements".
In fact they are all really nice guys and brilliant performers, we sold out the room and everybody had a great night.
