Help configure roon to dac 8 pro

Hi everyone,

I use Roon on Windows 11 paired with the DAC 8 Pro.

My intention is to connect it to a pair of 3-way speakers that have the woofers amplified with a dedicated power amp and the mid-highs with another dedicated power amp.

In addition to this, I also have two subs.

I thought of connecting a total of 6 channels to the DAC: woofer amp, mid-high amp, and two amplified subs.

can’t configure Roon correctly to manage this setup. Can you help me?

I’ve read other posts but the mixing part isn’t explained.

Currently connected:

xlr1 left woofer
xlr2 right woofer
xlr3 left mid-high
xlr4 right mid-high
xlr5 left sub
xlr6 right sub

Thanks a lot
