Anyone Using a Behringer dcx2496 with Innersounds

Hello: We are getting a modded Behringer dcx2496 Ultra from Sanders Sound Systems. Our system consists of the Innersound Eros with its dedicated X-Over Amp for the bass and a Threshold S/500 for the panels. I thought the Behringer was for multichannel setups. What does it do for a two-channel, two speaker setup? Is it worth putting another component into the chain?
