Default Re: Carbon is not -18dBFS like normal HD? Also, how to use S/PDIF?

The latency numbers with Carbon are less than half what HDX shows - very impressive!

I have some questions that I can't find answers to (or are curious oversights):

1. How can I use S/PDIF with Carbon? I can't see a way and that would be a real bummer of an omission - possibly deal breaker
2. How can it be expanded beyond the 24 I/O (I usually use 28 ins, but 30 when the band has a keyboardist)
3. The specs make it appear that Carbon is -20dBFS rather than -18dBFS like normal Digi/Avid IOs - is that right?
4. Does it possibly have SRC available on the ADAT I/O like 192s?
5. How long before preamp recall will be enabled like PRE and MTRX?

Thanks!
Hello.
1. We're planning to implement Optical S/PDIF support on the ADAT ports, but I can't say when that will be available.
2. Like BScout said, you can't at this time. Max is currently 25 inputs x 34 outputs.
3. Carbon has +24 dBu max input/output level which translates to -20 dBfs of headroom with a +4 dBu signal. HD I/O has less headroom than Carbon as it has a max input/output level of +22 dBu.
4. No SRC
5. Can't provide a time estimate, but it's a very high priority feature.
