Using the S/Pdif on a Delta 66 card.
...is it possible for me to use the S/Pdif as two more inputs...if so how?...
I use Cubase SX, PC and have the Delta 66/OMNI card setup.
I have considered using the extra SPDIF inputs to increase my total from 4 inputs to 6 inputs.
Here is what I understand is necessary to do this. You need some type of Preamp with an A/D converter on it. A few options would be,
the ART DPS DI/O Preamp System
http://www.zzounds.com/a--2676837/item--ARTDPS for $259.95. Another would be a Behringer Pre w A/D conversion. A couple of other suggestions, would be if you alread own a device that a preamp and some type of digital outs. For example, a Sony Minidisc with coaxel outs or a DAT recorder with the same digital outs. One last option I thought of, is if you have a keyboard like
a K2000. You could also use its digital outs and input into your card. I have done that with my music and it works great. The Delta card "locks" to the timecode of the K2000 digital signal @48khz - 16bit.
Either way, you will need some type of device connected digitally to the coaxel inputs. So, even if you get a Mackie mixer (unless it is a DB8 - digital board) then you will still need to convert the analogue signal to digital.
I hope this helps.
