I dare say the reason you're not getting a response is that your questions are quite basic, and perhaps the expectation of someone who can afford a dCS rig is that they're smart enough to read the manual :)
DCS elgar+ as word clock/DAC for PC
I've found a few high-end PCI cards with AES/EBU outs AND a BNC word clock input. Question is, can I run my Elgar+ in mastermode to utilize its word clock, what's the best way to accomplish that, and what's the best resolution I can expect to squeeze out of a MAC or a PC?
