Topic: Where to start configuring UCX and JRiver?

Setting up my new project and looking for advice on moving forward. I have all the hardware finally and a new windows based computer to work with. The goal is to use the RME UCX to feed 3 different amps. One for the horns on the speakers, another for the bass bins and the last amp for the sub. I will use Jriver and audiolense for DSP and have Jriver output 5 channels to the UCX. Also I have to get the Earthworks Mic setup on the UCX for measurements. I am dreading this because I have zero experience. Any tips on getting started would be appreciated. I know I will have configuration issues but it should work. I have the UCX manual and the Jriver wiki. Wish me luck.
