AES/EBU on multiple 96 interfaces

[Robin Reumers]

Hi,

At the moment I'm using an HD3 system with 3 96 interfaces attached.
I've connected my TC 6000 with 6 in and outputs going to the interfaces (3 x 1 in and 1 out xlr). The only problem is that when going to hardware in pro tools, I can only select AES/EBU output for the first interface but it is greyed out for interface 2 and 3, the inputs remain available though, is there a reason for this, and what would be the way to work around this?

Thanks

Robin
