Hello !
I ve just purchased an RME HDSPe AES card and  an ADI-8 DS mkiii converter .
I never had worked with AES connections so I have a couple of  questions ..

1.I can have up to 4 stereo  inputs and 4 stereo outputs with a single  25 pin cable between the interface and the converter ,is that correct?
2.Can I use the inputs /outputs as MONO channels inside total mix and also inside Cubase?
I mean, Cubase is going to recognize 4X stereo I/O or 8 X mono ?
For example, if I want to use 6 mono outputs for  5.1 monitor speakers and not 3 stereo ones ,
or if I want to record a guitar through a DI  then I have to use only one mono input of the converter ,not a stereo one ..
3.If I want to use a word clock (BNC) cable for clocking, and not clocking via AES, is it better to set the card as a master or  maybe the converter ? Do I need two BNC 75Ohm cables  for that case ? Or just one ?

Sorry if my questions are stupid but I m new in this

Thank you very much and Merry Christmas
