You should be able to use the Fast Track Pro at 24-bit 48KHz for 4 inputs (two XLR and two S/PDIF channels) and two outputs concurrently. You would not need to drop to 16-bit operation unless you needed four outputs at the same time.

The M-Audio manual seems to gloss over the need to synchronise to the S/PDIF incoming clock, but I assume they have done their job and that function is automatic.

hm.. I'm sorry I'm a bit of a newbie with all this. What does synchronize to an incoming S/PDIF clock mean. Will this setup not work? I read the bit about the 4 inputs at 24 bit if I only have 2 outputs. I seem to have missed that before.

Thanks!!

It should work OK.

When two devices communicate digitally, the receiving device has to have a way of locking its speed to the transmitting device so that data is not lost somewhere in the void between them. In some communication schemes, there is a connection for data and another for the clock (the timekeeping signal). In S/PDIF, there is only one connection that carries both the data and enough information for the receiver to reconstruct a clock. However, the receiver usually has to be told to do this rather than to use its own internal clock. On a quick look, there didn't seem to be anywhere in the M-Audio literature a way of instructing the receiver to take its clock from the S/PDIF data stream as well as just enabling the S/PDIF data input. However, M-Audio has a pretty good reputation, so I would be surprised if this didn't happen automatically.

sweet..

well I'll buy one and give it a go and if it works then I'll buy another one.. else it will go on ebay..

Thank so very much..
