That's a new one. But the manual says 3 so i guess it's not up to date. Anyway, that's good news then...

So one can access all 6 cards via total mix?

Also, i didn't find much info about cabling/syncing cards in the same computer in the manual, i take it i can use the 2 pin connector label sync in/out to sync cards?

I just want to make sure i get this right. My goal is to use the 9652/32 adat as input and listen to the result off all inputs through my 9632 analog out, is this going to work? Or do i need analog out for all soundcard?

Thanks for the speedy reply btw.

As Vincent observed, no internal routing between cards via Totalmix.
Mixer windows for the cards >3 are opened by Ctrl-clicking on the unit buttons.

Are you sure you didn't make a mistake earlier when you said the driver support up to 6 cards? Cause the manual clearly says up to 3 cards. I wouldn't want to make the mistake of buying too many cards...

thanks all for you help.

They have never been supported 'officially', but the option is there. We have industrial customers who have special motherboards and often max out the systems as much as possible. Those guys use up to 6 cards. But their hardware is capable to do so, they use special server boards with lots of bridges and PCI/PCIe slots. These are no standard computers. For the normal user more than 3 cards bears the risk that the interfaces are not fully functional or the system gets overloaded quickly.
