Frank, I did'nt realise that the audio wire card was a PCI!
That's OK, Phil. As long as we're all on the same page now.
So there we have it, mk2 traveller it is!
I did a little reading on this last night and from what I can tell, 2 major advantages of the mk3 over the mk2 are: more digital audio I/O (2 sets of ADAT connections) for a total of 28 in/30 out and MTC support...which may be important for Dean's criteria.
Peter: are your Travellers mk2 or mk3's? If mk2's, are there any MTC issues you've noticed?
