If anyone has experience with this system, the question is whether the Behringer DCX2496 file from Audio Artistry is programmed with xovers for subwoofers in addition to the xovers required for the line array.
I think you'd be better off having this thread moved to the multi way part of the forum. The full range forum is meant for full range drivers, some of them with helper woofer or tweeter. The multi way is home to the speakers with crossovers like a CBT.
Don't know this but that DCX unit is able to do just about anything involving 2 in 6 out, and includes a sum send. Cant see how you could not do what you need. I always tell everyone to use the AES digital input as a spdif in with a simple adapter, no need for transformer at all.
