Support 32x32 @96khz and 64x64 @48khz to DVS
Not sure if it will support 64x64 @96khz on Focusrite PciE Dante Card
Do I need the SQ Dante card to record directly to a computer with Dante Virtual Sound Card? Or can I use the network ethernet plugged to the computer?
yes you need the SQ Dante card. The build in network card is just for remote control and MIDI over TCP/IP.
It seems the limiting factor would be the DVS.
