Dynacord Mixing Table - CMS 1600 Recording studio

Good evening !
So I’m writing this because I really need help.
I bought a CMS 1600-3 recently, and I want to use it to record voice and instruments.
The problem is, I don’t know how to setup the mixing table with Cubase.
I installed all the drivers, the sound is detected when I use my mic, but I want to hear myself, like do monitoring, I don’t know how to do it… There are multiple channels on the mixing table (Aux 1,2 - Mono1,2 - Master ). Which one should I use ?

Thanks !
